Troy Smith Posted April 15, 2015 Share Posted April 15, 2015 First, a request, please only post a response if you have a question not covered here, or any corrections or additional information. Use the 'like this' button if it's of use but you have nothing to add to save thread clutter. Thank you. Various threads about Hurricanes have come up. The most confusing area for the modeller, and an important part of any model is the propeller, as it a very obvious focus point for a model. Now, in general the Hurricane is a simple aircraft for the modeller, the only other complex area are the early Mk I's, which had a series of changes and modifications introduced over a relatively short time. As a result, the British built Mk I Hurricane (see Canadian built section below) can have possibly one of five, maybe six, types of propeller and spinner, fitted in this order Watts 2 blade DH Spitfire Type DH Hurricane Type Spitfire Rotol Hurricane Rotol EDIT - Note the details below on the Hurricane Rotol spinners, the ES/9 and CM/1. As you need a good photo to tell the two apart, it is difficult to state what types was fitted to late Mk.I's, but both types are seen fitted to Mk.II's and Mk.IV's, and as Mk.I's did get retrofitted with the Hurricane Rotol unit, I expect both can be seen on Mk.I's There are not many photos of Mk.I's with the Hurricane Rotol unit as a factory fit, and I have not studied what units were fitted since the identification details were supplied. here's a great pre war colour shot of a Watts prop, which also shows well the inboard position of the landing lights on the fabric wing Hurricane mk.I by Etienne du Plessis, on Flickr This thread deals with some of the very early plane detail changes - http://www.britmodeller.com/forums/index.php?/topic/234950986-early-hurricane-mki-details-and-a-challenge-or-two/ This drawing is from a Peter Cooke articles called "Hurricane Veracity" showing the other 4 spinner shapes. [this misses there are two types of Hurricane Rotol] In this handy shot N - Spitfire Rotol R - Hurricane DH U - Hurricane Rotol [as these are Mk.I's, probably a CM/1] The exact reasons are to do with the quest for performance, and an area's operational requirements. The Watts 2 blade is a fixed pitch prop, which is average compromise for blade angle. The initial De Havilland unit was a 2 pitch propeller, with fine and coarse settings, though a modification kit to turn it into a constant speed unit was soon developed and fitted at unit level. The De Havilland unit initially fitted to the Hurricane was intended for the Spitfire, which has a slightly larger nose ring, so the spinner base is wide for Hurricanes nose. I surmise that these units were available, and as they made a big difference to performance were fitted and retrofitted to Hurricanes as they were available. De Havilland then developed a spinner specifically for the Hurricane, which was then fitted. From what information I have and discussion here this happened in early 1940 during the N**** serial aircraft, which was the 2nd Hawker production batch. One other point is the DH unit had metal blades. these two shots from the Ducimus Hurricane Camo and Markings guide, N2358 has the Spitfire DH unit, N2479 has the Hurricane DH unit. As can be seen the Spitfire DH is wider and blunter, and overhangs the nose ring, the Hurricane DH is more pointed and is correct diameter. It's hard to tell, but I think N2358 has a fabric wing, while N2479 has a metal wing. The position on the landing lights is a wing bay inboard on the fabric wing compared to the metal wing. (N2358 shows the diorama possibilities of the Airfix Albion refueller too ) The Rotol Spitfire type spinner seems to have been introduced onto the Gloster built third batch of Hurricane in February/ March 1940. Graham Boak in a thread on Luftwaffe Experten Message Board (LEMB) still up but no longer active, suggested they appear from the P27** serial range onwards., which would be P2535 - P2584 (50), P2614 - P2653 (40), P2672 - P2701 (30) from http://www.k5083.mistral.co.uk/APS.HTM which says after P2682. what is of not clear is the introduction of the Hurricane Rotol (the 'bullet' spinner seen on the Mk.II) being used on Gloster built Mk.I's The earliest example I know of is V6825, TM-F of 504 Sq, I think it was fitted with a CM/1 unit. V6825 5 MU 29 September 1940, 504 Sqn 1 October 1940, India 13 August 1943, SOC 11 December 1944. see here for more discussion... https://www.britmodeller.com/forums/index.php?/topic/235078582-hurricane-rotol-spinners-the-cm1-vs-es9-quest The Rotol unit has blades made out of Jablo, a compressed wood composite, and was lighter than the DH unit. From what I can gather this gave the best performance to the Hurricane, and the became the preferred unit during the Battle of Britain. Again, as developed for the Spitfire it is too large for the Hurricane nose ring. see also http://www.a2asimulations.com/forum/viewtopic.php?f=10&t=12029 This has a lot more technical information, but also some dates, note there are many links to quotes and documents here http://www.wwiiaircraftperformance.org/hurricane/hurricane-I.html Links to information regarding two-speed vs Constant speed propellers http://www.network54.com/Forum/149674/message/1429177650/CS+vs+two+position+props... The 'bullet' Rotol unit was the Hurricane specific unit, and is unit seen on all Mk II and IV's, but also on some late Hurricane I's, and was also retrofitted, an example is P2617, the Hendon Hurricane which has this fitted from it's time in Training Command. 510 510 sq in France, May 1940, shows blade shape very well. The 'bullet' Rotol unit was fitted with two types of blade, and from looking at photos, the Spitfire Rotol had a slightly different blade compared to the initial Hurricane Rotol type. this is captioned as being a 1 Sq RCAF aircraft, looks to be BoB era, note the rounded tips compared to the angled in photo above Edit - posted on Hyperscale http://www.network54.com/Forum/149674/thread/1429144547/2/Airfix+1-48+scale+Hurricane+Mk.I+Review Quote Props for the Mk.I are as follows: Watts Type Z38, 11 ft. 3 in. DH Hamilton two-position, 11 ft. Rotol RMS7 variable pitch, 10 ft. 9 in. Some late production Gloster-built Mk.Is have the Rotol props same as the Mk.IIs. Rotol R.S.5/2 with Schwarz blades, 11 ft. 3 in. Rotol R.S.5/3 with Jablo blades, 11 ft, 3 in. EDIT 2/5/15 Graham Boak has mentioned that there are possibly two types of 'bullet' Rotol. EDIT Confirmed in 2019. See below of ES/9 and CM/1 Quote The point that there maybe 2 Rotol Hurricane spinners is fascinating. I noticed that the spinner on KW924 does look longer than on KZ320. Another things to ponder on when going through photos! VE day Edit... on the Key Forum, https://www.key.aero/forum/historic-aviation/3867571-hurricane-nose-profiles-not-always-quite-the-same?page=1#comment-2003783 this was posted. @Anneorac is also a member here. Quote Moving on to the Hurricane II we have the bullet shaped ES/9 spinner and the slightly longer CM/1. The difference in shape between the two is very subtle with the ES/9 having a constantly increasing curve from the back plate to the nose while the CM/1 has a flatter curve from backing plate to just in front of the blades and then a slightly steeper curve from that point. The easiest way of telling the difference is but looking at the way spinners attach to the back plate. The ES/9 is attached by six locking studs on the spinner so if you can see two small holes on the spinner between the blades, you are looking at an ES/9. Just be aware if you are looking at a close-up, DH spinners attach in a similar way. The CM/1 spinner is locked by a single slot located on the backing plate so if you can’t see any holes on the spinner you may be looking at a CM/1. If you are lucky and the prop has stopped in the correct place you may even be able to see the slot in the backing plate. so, from the above, I found this while looking for something else This is the CM/1 The CM/1 spinner is locked by a single slot located on the backing plate so if you can’t see any holes on the spinner you may be looking at a CM/1. If you are lucky and the prop has stopped in the correct place you may even be able to see the slot in the backing plate. The ES/9 is attached by six locking studs on the spinner so if you can see two small holes on the spinner between the blades, you are looking at an ES/9. Just be aware if you are looking at a close-up, DH spinners attach in a similar way. both from http://ava.org.ru/iap/78m.htm From photos, the ES/9 seems to the far more common unit fitted. Note, but there does not seem to be a pattern on what spinner was fitted, both are seen on all through II and IV production, now I know what too look for, I keep spotting CM/1 units. see here https://www.britmodeller.com/forums/index.php?/topic/235078582-hurricane-rotol-spinners-the-cm1-vs-es9-quest This patchy survey shows that the CM/1 was the type fitted most at first, but that is from the few photos where the spinner type and serial is visible. I don't think I have ever seen a photo of a MK II or Mk IV with anything but bullet Rotol of either type, but there are two blade types. this ,( a 151 wing Hurricane in Russia BTW) which is the earlier type This is the later (i think) type of blade fitted to the bullet Rotol, note the lack of the bottom 'corners' on leading edge Note from this angle it is hard to assign what spinner is fitted. The Mk V Hurricane, of which two prototypes were made, was fitted with a 4 blade unit, the same as fitted to a Spitfire IX. The DH Hurricane unit was the preferred fit for Tropical Mk I's, perhaps the metal blade being considered more durable than the Rotol unit, and on the Sea Hurricane I, where the extra weight helped counterbalance the weight of the arrestor hook. Tropical Mk I Sea Hurricane IB, also fitted with a oil ring behind spinner to deflect oil leaks from prop. the lack of the rectangular access panel and difference in tones between metal and fabric covered areas is also of note. Land operated Navy Hurricanes, and CAM ship Hurricanes vary, and Mk II Sea Hurricanes have the bullet Rotol. Canadian Built Hurricanes. 2022 Update Thanks to @Carl V /Carl Vincent for providing information and photographs to update this part of the story, as well as @airjiml2/ Jim Bates for information. In short in 1941 there were many Canadian built Hurricane Mk.I without engines or propellers. There were Fairey Battle trainers with Merlin III engines. It was decided that the fighter were more important than bomber trainers, and the order went out to take these Merlin III engines with their propellers, and to cut down the prop blades, and fit these to Hurricanes. These have become know as "Battle Hurricanes" these images show these props fitted left, with the later Hamilton Standard unit fitted right for comparison The propeller on the right, the Hamilton Standard, became the standard unit fitted to Hurricanes used in Canada. but the subsequent X, XI, XII and XIIA were fitted with a Hamilton Standard unit, usually without a spinner, though some had specific Canadian spinner fitted. But, exported Canadian Hurricanes had their Packard merlin engines removed, and British Rolls Royce engines then fitted, and so were refitted with the Hurricane Rotol, and become a Hurricane IIB. Some Canadain built aircraft were rewinged with C wings, and a few were converted into either hooked or Sea Hurricanes, again, some retained B wings (see the famous images from Operation Torch) or with rewinged with C wings. This is worth a thread on it own, which needs writing and linking in. Even more confusingly are the Sea Hurricane I or X, retained in Canada for shore duties, which had the DH Hurricane unit. or in the case of Sea Hurricane conversion, a DH unit. Quote The RCAF also received Sea Hurricanes. Yes, the RCAF got some Sea Hurricanes complete with hooks. They were built by CC&F for the FAA but were diverted to Canada. They were in the BW835 to BW884 serial range. The RCAF Sea Hurricanes were basically a Hurricane Mark I with a hook, a DH spinner with a cut down Battle prop, and an eight gun wing. Early in service they carried the Fleet Air Arm scheme of Extra Dark Sea Grey/Dark Slate Grey over Sky. (A common misconception here is that they didn't have hooks. I can't confirm if they all had hooks or some did and some didn't but this one sure did.) This one is BW850 BV-T of 126 (F) Squ. RCAF Finally, there are the Canadian built Hurricanes. I am indebted to this blog posting for some details on this. see http://ascalecanadian.blogspot.co.uk/2007/10/rcaf-hawker-hurricanes-part-1.html the Canadian built Mk I's were fitted with the DH unit [type? - check] I'll work on doing some kit spinner and propeller comparisons later. 34 Link to comment Share on other sites More sharing options...
Troy Smith Posted April 15, 2015 Author Share Posted April 15, 2015 I don't 'do' 1/72nd, so don't have a selection of kits to reference, but in 1/72nd the Hurricane is poorly served, and most of the kits have serious shape errors. In 1/144th there are only the old Revell kit, which is very inaccurate, and the Sweet kit, which looks to be very good, but is a MK I only. In 1/32nd the choice is the PCM Mk I, which seems to be had to get, or a lot work upgrading the Revell kit. Hint, get the PCM kit. In 1/24th, their is the Airfix kit, which is a Mk I, and suffers from having a too deep nose to fit the to scale Merling, and thus has a too big spinner, both in diameter and length. I've been working on a fix on an old one, but the blades are well shaped for the angle tip Rotol blade. Trumpeter do several 1/24th kits, a Mk I, IIC, IIC trop and IID. I have the IIC trop, and overall it's very good, but the spinner is misshaped, being a bit too tubular. I don't have the Mk I too comment. I 'do' 1/48th, This will take some typing, so I'll edit more in later There are Monogram - 60's moulding, closest to a IIA. prop and spinner is OK Airfix - Mk I, has the Spitfire type DH and Rotol props, both well shaped, though the Rotol has too large a diameter of blades according to Iain Wyllie. This I need to double check. Hobbycraft - a IIC, based on the Airfix, has the best shaped bullet Rotol of all the Mk II kits though! Hasegawa - issued in many boxings, see here http://modelingmadness.com/splfeat/kr/has48b.htm 3 types of prop, DH Hurricane, Rotol Spitfire and Rotol Hurricane bullet. also 3 prop blade sprues, sprue W - 3 parts, De Havilland 10’9” propeller and spinner Sprue D - 1 part, Rotol later metal propeller Sprue X - 1 part, Jablo 11’9” propeller Note, the 'later metal' D Sprue is the earlier type Rotol fitted to the Mk II, and the sprue X is the later type mk II IIRC. I can't check just at this mo. Classic Airframes - Fabric wing Mk I, has quite a few issues, and is based on the Hase kit. Has a Watts 2 blade, a Spitfire Rotol and Hurricane bullet Rotol (which I have never seen on a fabric wing Hurricane) Pegasus - based on Hasegawa, it's a BoB Mk I with Spitfire Rotol. Ark - based mostly on Airfix, but with detail parts based on Hasegawa, crude moulding, and tricky to build without a lot of work. Does have 3 props, DH Spitfire, Rotol Spitfire, remarks per Old Airfix, and Rotol Hurricane bullet, which is the 3rd best shaped bullet. Italeri - have done a Mk I, with a DH Spitfire? and Spitfire Rotol, I put ? as Italaleri made the nose ring too big, and then made spinners to fit. The Rotol one is maybe salvageble, the DH one is hideous. A Sea Hurricane I, with only the mishaped DH IIC, with a really misshaped spinner, to broad at the base, then going into a weird nipple like tip. Vile. more on the 'joys' of the Italeri kit here http://www.britmodeller.com/forums/index.php?/topic/234935596-sea-hurricane-148-italeri/#entry1390213 New Airfix, not got one yet, but looks good. I will edit in more later, like the comparison photos I need to take.... 12 Link to comment Share on other sites More sharing options...
tonyot Posted April 15, 2015 Share Posted April 15, 2015 Sea Hurricane Mk.Ia `Hurricat' Note; I have noticed that many `in service' MSFU `Hurricat' Sea Hurricane Mk.Ia`s were refitted with the bullet spinner Rotol, presumably because this gave a much better climb rate which was much needed in the Hurricat role. I have also seen a blunt Rotol unit on another MSFU Hurricat, but I would think that this was quite rare? Cheers Tony Link to comment Share on other sites More sharing options...
airjiml2 Posted April 16, 2015 Share Posted April 16, 2015 Troy, You have paraphrased my article incorrectly. I'm working on an article that should be published later this year with more details, but basically: CCF Hurricanes built on RAF contracts were fitted with RAF equipment in the UK. CCF only had a few engines and props to flight test the Hurricanes before delivery. RCAF Hurricane XII and XIIa were fitted with Hamilton Standard props. The XIIs were RCAF serials 5376 to 5775. XIIa were rebuilt Sea Hurricanes and what I referenced as Hurricane Xs. There is no such thing as a RCAF Hurricane XI. Not sure where "common knowledge" about these aircraft came from. They all appear to be British contract aircraft. What I called Hurricane Xs in that article...which may or may not be in error; RCAF records called them Hurricane Mk. Is or just Hurricanes...were fitted with Battle props (and engines). These aircraft were RCAF serials 1351 to 1380. Survivors of this batch were rebuilt as Hurricane XIIa. The Sea Hurricanes operated by the RCAF were diverted from British contracts and fitted with British equipment. All photos I've seen show DH pointy spinners. In the article I said they were fitted with Battle props, but they may have just been standard DH props. These aircraft were BW835 to BW884. Survivors of this batch were rebuilt as Hurricane XIIa. "Free issue" Hurricanes XIIs may have been fitted with RCAF equipment but the engines and props would have been removed when delivered to the RAF. Hope this helps, Jim 1 Link to comment Share on other sites More sharing options...
Troy Smith Posted April 16, 2015 Author Share Posted April 16, 2015 (edited) Hi Jim I don't a great deal about the Canadian Hurricanes, which I why I used the basics from your blog, I was mostly trying to sort out the finer details of the British made props, and added your Canadian information I could find to make reader aware of the different propeller fitted, but it was more of a footnote in an attempt at completeness. So, thank you for adding some useful corrections and information. I look forward to your updated article and please inform us when you publish it, will this be on your Scale Canadian blog? For anyone who has not checked the link, there is a great photo of a Mk XII with rocket rails! I should have added that as many warbirds are from Canadian built airframes, the Canadian spinner is not an uncommon sight., for example one of the 3 Hurricanes in the Battle Of Britain film is Canadian and fitted with this type of spinner. here's a shot from the film, with a very helpful shot of this Canadian spinner, usefully contrasted with the Rotol 'bullet' (an ES/9 I think) But, AFAIK, this spinner is not available in any kit or aftermarket, though Ultracast do the spinnerless version http://ultracast.ca/products/48/148/default.htm Edited August 16, 2020 by Troy Smith pic replaced 8 Link to comment Share on other sites More sharing options...

It'd not bad, better than the Revell by far, but nowhere near as good as the Sweet kit. I would build one if I didn't have a cupboard full of Sweets. It suffers from having non Frise ailerons: the chord is excessive on the upper wing surface. Edited April 16, 2015 by Work In Progress 1 Link to comment Share on other sites More sharing options...
Graham Boak Posted April 16, 2015 Share Posted April 16, 2015 (edited) That's an interesting point from Tony. It is said (where it is noted at all) that the Sea Hurricane had the DH prop because it was heavier, to balance the arrester gear. However, the Sea Hurricane Mk.Ia as used on the catapult ships (whether CAM ships or RN) didn't have the arrester gear, so would be free to use whatever prop was available or the "donor" Hurricane came with. It really should be said that it was the Sea Hurricane Mk.Ib which had to have the DH prop. A good summary Troy, I was particularly interested in seeing the Canadian spinner highlighted.

tonyeh Posted April 16, 2015 Share Posted April 16, 2015 Anyone know why there was so much farting about with spinners on the Hurricane? Or is that a stupid question? 1 Link to comment Share on other sites More sharing options...
Graham Boak Posted April 16, 2015 Share Posted April 16, 2015 The simple answer is that there were a number of different propellers on Hurricanes, so a number of different spinners were inevitable. There were two different Rotol spinners because the initial design was designed around the diameter of the Spitfire's nose. If you look closely at the photos of the first experimental Hurricane with the Rotol, you'll see that it had a modified nose shape to meet the Rotol spinner cleanly. This was not adopted for production, so when it was decided that the Hurricane should have priority in the fitting of constant speed props, the step down appeared behind the spinner with, I suspect, the oil leaks that led to the fitting of the oil spill ring on the nose. By late 1941 the production of the proper Hurricane spinner was in hand and this appeared on service aircraft. I've no idea why there was a specifically local Canadian spinner, but this may have something to do with how the Hamilton propeller hub differed from the DeH one. Other aircraft types also had different spinners during their development - the Spitfire had more than the Hurricane, thanks to the fit of the Griffon. 1 Link to comment Share on other sites More sharing options...

tonyot Posted April 16, 2015 Share Posted April 16, 2015 No he means Hasegawa 1/72nd scale which is a dead ringer for the Connie spinner. The Hurricane restored in Malta also had a Connie spinner fitted although when I was there last this had been removed so hopefully they have a more accurate looking one fitted by now? Still a great restoration nevertheless. Cheers Tony Link to comment Share on other sites More sharing options...

Troy Smith Posted April 17, 2015 Author Share Posted April 17, 2015 Cheers Troy for this. So are there any guidelines for when the oil deflector ring behind the spinner was fitted? Jonners Good question Jon Andy L posted this here http://www.britmodeller.com/forums/index.php?/topic/234963507-all-the-hurricane-questions-you-want-to-ask-here/page-3#entry1687630 In answer to the oil ring question - photo taken of a 615 Squadron Hurricane, late October 1940 at Northolt But, apart from that, refer to photos, I presume this is the earliest one Andy could find, and is also a great shot of the spinner shape. EDIT - the oil ring was needed as the constant speed units leaked oil, which blew back onto the windscreen. an example of the oil leak is shown here, visible on spinner, and top of cowling. Plane is 85 Sq, VY-K, supposed to be 'Sammy' Allard's, taken at Castle Camps, July 1940. Part of a series of Life photos, often reproduced, also of note is the non standard paint demarcation, indicating an in field repaint of 'sky' and the very chipped paint on wings, seen on a few Hurricanes in 1940. Note also the distinctive oil stains on the UC doors. 1 Link to comment Share on other sites More sharing options...

Partly yes, and partly because the RAF did not supply spinners for RCAF contract aircraft. So the RCAF adapted and used a local design.

Graham Boak Posted April 17, 2015 Share Posted April 17, 2015 That doesn't explain why they didn't simply use an established design.

One reason may be contractual difficulties: DH not having the rights to sell Hamilton-linked things in Canada As I said above, it was partly because the neither the DH nor Rotol spinner would fit over the Hamilton Standard hub. Also, I can find no evidence of any Hurricane spinners with CCF other than the DH design and a Hamilton Standard hub sure isn't fitting in that spinner! The more interesting question, is why they felt the need for a spinner? So many RCAF Hurris operated without them, so why were some fitted? I had a few theories, but none of them are born out in practice. Jim Edited April 17, 2015 by airjiml2 1 Link to comment Share on other sites More sharing options...

I would have been quite happy identifying that as a DH prop - maybe it is, I'll have to go looking into books on the Battle. As far as I understand the dome was largely decorative, or at least protective. The question I raised was whether this would be a different large dome with the Hydromatic version.
