Jamie @ Sovereign Hobbies Posted October 6, 2019 Author Share Posted October 6, 2019 I have drilled out one of the Flightpath air to air refuelling pods to feed a wire through to the helicopter. Unfortunately though, this was the first time I tried the wings together. I already bought the new corrected Alison engine nacelles as seen earlier in the thread. This is how they compare to the kit's engines which, (and I'm not particularly clued up on C-130s so correct me if I go awry here) were based on a C-130A which used dinky little engines: Unfortunately there's a drastic shape in their cross sections as well as length which I hadn't understood before This means that the Flightpath engines fit perfectly where they touch the kit's wings For what it's worth, Flightpath's engines do appear to be correct: ...but that doesn't change the fact that they're going to be an absolute pain in the proverbial to use and not just once but four times. Mr Parkins, if reading, then it may be an idea to upgrade the conversion to include the fairings into the top wing halves here and then all the buyer has to do is cut out between the panel lines on each. That will probably have to be my approach here, of a fashion. 6 Link to comment Share on other sites More sharing options...
Jamie @ Sovereign Hobbies Posted October 6, 2019 Author Share Posted October 6, 2019 Eight plasticard fillets were cut out to pack the nacelle sides attached to the lower halves of the wings: ...which were in turn glued to the insides. Meanwhile, I made up some Milliput which is not my preferred filler for general use but it is suitable for packing out the fairings on the upper halves. 10 Link to comment Share on other sites More sharing options...

With the wings out of game whilst the Milliput cures, I resumed work on the chopper. As the S-61 family all (with exceptions) have a boat hull I made a hard balsa wedge This was intended to serve as a mounting block. The top was faced with plasticard ...and the floor drilled as can be seen. I soldered the positive cable to an M3 nut and glued this to the top of the mounting block. An M3 screw had its head ground down until it was a good press fit into the carbon fibre tube to get a good electrical connection the it was secured in the threaded section with some CA wicked in. And thus, I have a helicopter on a stick. Also, my modelling table has been taken over by children, and I'm hungry so this is enough for now. I don't think I have any more excuses for not cracking on and finishing the HH-3E Jolly Green Giant now. 10 Link to comment Share on other sites More sharing options...
Richard E Posted October 6, 2019 Share Posted October 6, 2019 Good to see this project coming together again Jamie. Because you probably haven't got enough to do, is there any way you could take a recording of the radio chatter between the tanker and receiver from the web and then build a simple "press to play" speaker to the base ? 3 Link to comment Share on other sites More sharing options...

Hi Richard, I'm afraid I have no idea how to do that - but I try to be a tolerant, inclusive sort so I've no objections if you want to do the voices and radio squelch noises for me and we can just pretend it's a feature of the model Here's how much needs to come off the engine nacelles where they fair in to the wings. 5 1 Link to comment Share on other sites More sharing options...
Jamie @ Sovereign Hobbies Posted October 7, 2019 Author Share Posted October 7, 2019 I won't claim this is the best way or even a good way to begin, but I intend to chisel more or less parallel to the thrust line as far back as I can get. To aid this, I have used a razor saw parallel with the leading edge of the wing in plan-view to saw down to the marked lines, when viewed from in front. Application of chisel shall therefore cut away the excess material leaving what should hopefully clean up to be a smooth transition of the new engine nacelles. That then should (he says, ha ha) leave only the reprofiling of the fairings up over the leading edges to address. Getting the basic cross section of the nacelles correct first seems like the priority for now though. It's very difficult to shape a fairing when one doesn't have the thing it's fairing in to which may sound obvious, but having seen some rather odd shapes created (both by myself and many others) over the years in the r/c modelling world where building from raw materials is much more common, it is my preferred sequence now. 5 Link to comment Share on other sites More sharing options...
Jamie @ Sovereign Hobbies Posted October 7, 2019 Author Share Posted October 7, 2019 I used a sharp, flat chisel and my most delicate sledgehammer to knock chunks off as described above: Next the wing was chiselled more and sanding to bring the remaining excess down to match the aerofoil section: It's getting there but, the contours aren't right - the nacelle bulges outwards from the resin into the wing, so more fine removal of plastic and tactical use of Infini Model hard sanding sticks or softback sanding sticks have got it there or there abouts. I'll leave this one now and get the other 3 to a similar state. To break up the monotony of doing the same task over and over, I'm going to try to finish this Zvezda Mil Mi-8MT "Hip" which Stew bought for me at Scottish National Scale Model Show: 9 Link to comment Share on other sites More sharing options...
Jamie @ Sovereign Hobbies Posted October 7, 2019 Author Share Posted October 7, 2019 I braved the wind and cold to drill out the 3 remaining resin engine nacelles Whilst in there, I raided my old R/C stash which hasn't been touched since I moved house in spring 2014 when I was taking home almost 3 times as much money and found some brass tube in larger sizes than my Albion Alloy stuff, and also pilfered a drogue from a Revell issue of Matchbox's old HP Victor kit. 7 Link to comment Share on other sites More sharing options...
Jamie @ Sovereign Hobbies Posted October 7, 2019 Author Share Posted October 7, 2019 I'm quite liking this unemployed thing, at least on a very short-term basis. A 1/8th inch diameter brass tube was a pretty good match for the Whirlybird kit refuelling probe. For the telescopic section, I had a brass rod that a) fits the tube well and b) looks ok so those two were cut to length. A second piece of the outer tube was cut approximately 3mm long and a length of cable soldered to the outside. I cut the drogue short, drilled it and reamed it out to fit the collar nicely, then carefully glued it in. I now have a electro-conductive refuelling hose. The brass tubes needed dressed up with little plastic collars and a better forward mounting bracket, so I cut bits of plasticard, drilled and reamed them out to fit the tube then filed and sanded down to suit. Ish. A power drill chuck may have been employed to preserve my inherent laziness. Once that was done, but prior to gluing the plastic bits in place, I fed the helicopter's cable through a hole in the side of the fuselage then soldered it inside the tube. The kit's resin aft end was retained, hollowed out, and glued on to the brass tube. I trust it's fairly obvious at this point, but here's how the refuelling drogue fits on. This should allow me to unplug the Herc from the Jolly Green and unscrew both models from their support rods. He says... 9 Link to comment Share on other sites More sharing options...
Stew Dapple Posted October 7, 2019 Share Posted October 7, 2019 Hell's dangly bits, you're making the most of your time off, aren't you? I thought fairing in those nacelles was about a week's work in itself Okay, you've still got three to go but you've got your proof of concept... Looking impressive, crack on mate Cheers, Stew 1 Link to comment Share on other sites More sharing options...

I've done two actually And with the probe stuck to the helicopter, and the drogue hose fed through the refuelling pod (it had two holes drilled to meet each other - the cable needed some careful manipulation to feed it through), we can sort of imagine how this should pan out... 9 Link to comment Share on other sites More sharing options...

Some mightily impressive cutting / chopping / scribing / filling & gluing going on. That Mil 8 looks tasty! Thank you! Getting the cuts and chops in the right place and the right depth is a trick I haven't fully mastered yet! I finished the Mi-8 today, but most of the morning was dedicated to the pre-start meeting with our builder, quantity surveyor and architect. We hope to have people on site from the 22nd of this month which will be nice, considering the fire was on 4th January. I am ready to join the fuselage halves of the HH-3E now. I used hot glue to secure the cables inside. Before closing up, I wanted to fix that shape difference. Does the reader recall this picture? I fixed this using a hair drier. The mating surfaces needed to be re-levelled after the starboard side "roof" was bent down a little lower, but now it's a fairly good fit. I find a hair drier always works a charm when needing to adjust the shape of resin pieces. I, umm, think I'm ready to glue it together. I should check the electrics function correctly one last time before I do or you'll hear me screaming from around the globe if not. 7 Link to comment Share on other sites More sharing options...
Jamie @ Sovereign Hobbies Posted October 8, 2019 Author Share Posted October 8, 2019 After a brief panic following a failure to work, I moved what seems like half a tonne of temporarily stored boxed-up possessions to discover some fresh D-cell batteries. The tired AAs in my daughters' electronics playset appear to be fairly flat. We're back in business, but I think there is some appreciable voltage drop across all this cabling so I *may* have to up the power supply voltage with another cell to compensate once the C-130 is all wired up too. Latest motivational video clip here (the blades were painted this morning) https://www.facebook.com/jamie.duff.75/videos/10157599320921489/ This is a proverbial milestone. The helicopter fuselage halves have been joined. Ta dah! 6 Link to comment Share on other sites More sharing options...

Jamie @ Sovereign Hobbies Posted October 9, 2019 Author Share Posted October 9, 2019 Last night I started on the ramp which needed a bit of fettling. That's in now. The plastic side skirt of my old car (14 year old 122,000 mile Jag X-Type) was hanging off a bit. I had to weld a patch on the back of the sill a few years ago and didn't buy new clips, but more recently one of the front ones that was intact broke so it was looking a bit shonky and I wanted it secure before snow removed it completely one day, so I bought new clips (9 quid for a full set for both sides was OK). I went to reattach it the other day and when pushing the broken off remains of previous plastic clips out of the wholes, the sill around it moved and made a crunchy sound. Lovely. Hence, today I mostly have had to prioritise doing this because the MOT is due next month and I'm off work this week so it's only fitting that I use my time off lying on a garage floor. I decided to just do most of the remaining sill. Which was tacked thus: ... properly welded up, painted in aluminium-zinc primer then undersealed. I am just about to go back outside to drill new holes to reattach the plastic skirt like I meant to do in the first place. But first, here's what I found with the HH-3E's windscreen! It's beautifully cast in clear resin and nice and transparent. It's as good as most injection moulded plastic canopies I've seen. But alas, it was a bit taller than the fuselage. I lowered the sills by the amount shown by the pencil line and the highest points now more or less match, however a more challenging issue presented itself: Oh dear. Now, had I been more intelligent I'd have checked this before closing up the fuselage with a fragile cockpit and electronic components inside, so wet sanding is right out the window here. The S-61 family does have a fairly significant cross section change in the forward fuselage, but in real life it all happens within the length of the engines and the fuselage from the front of the air intakes (or maybe just a smidgeon forward) to the canopy is a constant cross section irrespective of whether it's a short nose S-61 like the Sea King, or a long nose S-61 like the L,M,N or R (CH-3 or HH-3E or F) models here. The long nose S-61s are lengthened with a plug the same cross section as the aft extremity of the cockpit glazing. For my model now, at this stage, that's just too hard I'm afraid so I have compromised and this will feature a cross section change to blend in the glazings. Sorry folks. I shall try my best to hide that by finishing this helicopter as a somewhat used dead-flat-matt finish so that reflections don't give the game away easily. I used Infini Model's epoxy putty and a little bit of water to kinda scuplt out the shape it needs to be. This will probably need further work to get a smooth finish but the epoxy putty should get me most of the way there. 8 Link to comment Share on other sites More sharing options...

Jamie @ Sovereign Hobbies Posted October 9, 2019 Author Share Posted October 9, 2019 Who's a silly boy? I was careless and have gouged out a bigger chunk than I meant to. This will need careful build up of filler which I'd hoped to avoid! 2 1 Link to comment Share on other sites More sharing options...
