perdu Posted May 7, 2015 Share Posted May 7, 2015 Kev if you go to your pic at the top of post #22 the curved piece at the base is really a straight vertical which has a small trim panel all up its trailing edge that is actually a flat piece that cuts the airflow as a tee section I first noticed that some time ago and it did feature in a build I remember, almost certainly in here I dont think it will take much looking to research it, I'll have a look tomorrow Link to comment Share on other sites More sharing options...

perdu Posted May 8, 2015 Share Posted May 8, 2015 (edited) Kev I'm sorry but I have virtually no decent shots of the VC10 but if you follow one of the links on the tags for this build to Radleigh's visit to Brize you can see on a couple of the very atmospheric shots some of what I mean http://www.britmodeller.com/forums/index.php?/topic/234975329-vc10s-and-tristars-raf-brize-norton-2-belfast-shots/ There is a close up from behind of the lower rudder upstand and you can make out the flat trim spoiler across the trailing edge just about And just had a quick scan round with Googly and found this: The rudder 'looks' like a curved thing but is actually three straight lines And each individual trailing edge has a flat piece across it, making a sort of tee shaped edge Where you'd think it was a sharp finished edge but it isn't Sorry if this is useless info, the Ten is kinda special and I so enjoy seeing one built Edited May 8, 2015 by perdu Link to comment Share on other sites More sharing options...

perdu Posted May 8, 2015 Share Posted May 8, 2015 Some nice shots on the facebook page for XR808 which is being taken (eventually) to RAFM Cosford too Kev There's a good shot of the tapered fin leading edge I noticed http://www.facebook.com/XR808 Link to comment Share on other sites More sharing options...
xffw45343tg Posted May 8, 2015 Share Posted May 8, 2015 ... And each individual trailing edge has a flat piece across it, making a sort of tee shaped edge Where you'd think it was a sharp finished edge but it isn't Great picture; I'd never noticed the "coke bottle" profile of the tailcone. I guess that flat piece on the trailing edge of the rudder works a bit like a Gurney flap? Kirk Link to comment Share on other sites More sharing options...

Kept the airflow organized and stopped the rudder from inducing random yaw under certain conditions. Cheaper than redisigning the whole rudder. Keeping sharp trailing edges turned out to be not worth the effort as a tiny flaw would ruin the airflow. Take a look at a Dash-8 trailing edge on the flap. Literaly looks like an I-beam! 2 Link to comment Share on other sites More sharing options...

Cheers Radleigh, if you have photos on the top part of the engines and the top of the T tail, all my info will be based on the Brooklands VC10 as there are some noticeable differences. 1 Link to comment Share on other sites More sharing options...

perdu Posted May 8, 2015 Share Posted May 8, 2015 Yes Kev that's the dooberry The flat spoiler is part of it but I really meant to note the straight edged 'curves' on the rudder Isn't that a great photo... Link to comment Share on other sites More sharing options...

At the risk of drifting off topic, it continually surprises me when getting up close and personal with real aircraft how "dirty" they appear to be aerodynamically. The 152s and 172s I did my PPL in have quite deliberate 'corrugations' on the control surfaces designed to induce all sorts of clever turbulent flows to improve their performance close to the stall etc. My favourite bit is the bent bit of metal on the base of the rudder to counteract propeller wash. Not the polished smooth sleek machines I imagined. So, big sticky-outy strips on the trailing edge of the rudder come as no great surprise even in the 2nd fastest passenger airliner...

kev67 Posted May 10, 2015 Author Share Posted May 10, 2015 Just got back from Brooklands, had a great day their, took loads of photos of the VC10, looked at the tail and realised what Perdu was talking about. Chatted to the staff, one was the flight engineer on BOAC VC10's, got plenty of information including the length of the fuselage for the Standard civil version VC10, which if anyone is interested is 133' 8", (1/72 scale is 566.42mm) looking at the AIrways kit is actually spot on as the Airways kit is a little longer but as the kit is for the military version it has the APU on the tail, which the Brooklands one has not. This I believe you mean Perdu 1 Link to comment Share on other sites More sharing options...
perdu Posted May 10, 2015 Share Posted May 10, 2015 The important question is whether you would have picked up on the 'straight not curved' rudder shape if I hadn't opened my big gob Kev I love how you tackle these awkward jobs Disappointed that I missed Brooklands Classic Cars Meeting this New Year's Day, it's an event I try not to miss even though it a long run down from Brum, in my Midget Usually get some nice aircraft photos down there Link to comment Share on other sites More sharing options...

kev67 Posted May 10, 2015 Author Share Posted May 10, 2015 The other thing I will have to do is alter the boom on the tail,and give it more curvature as the kit is to straight, I'd imagine it would be similar on the top view, so if anyone can help 1 Link to comment Share on other sites More sharing options...
kev67 Posted May 27, 2015 Author Share Posted May 27, 2015 Small update, I have completed the tail section, sprayed some Tamiya primer on, so I can check for areas that need re-doing, micromesh the primer down and scribe the panel lines on. Next I can start on the engines 12 Link to comment Share on other sites More sharing options...

kev67 Posted June 13, 2015 Author Share Posted June 13, 2015 Small update, I have begun to build the engines, I have decided to use the Anigrand VC10 engine fronts which I will take a resin copy off, and glue this to the vacform engine, the Anigrand seemed to have the engine blades in the wrong place, so these have been removed before I take a resin copy. I have added some of the vents and various holes that are evident on the VC10 engines, the small vents will be made by cutting out square sections where the vents will be located, filled with milliput then a impression of the vent will be pushed into the milliput and allowed to dry I have yet to decide how to tackle the grills at the rear of the engines, I had plans to draw these in Rhino and have them printed out 4 Link to comment Share on other sites More sharing options...
kev67 Posted July 13, 2015 Author Share Posted July 13, 2015 Time for a update, if anyone thought I had given up on this, not yet anyway. I have finished detailing the interior using reference photos from Brooklands, I was told that the front galley is the original when it flew in BUA colours and was not altered. This section only needed detailing as the rest will not be seen and its not worth adding passenger seats as the windows are to small anyway. The only other thing now is to make the 5 cockpit seats, and then I will be ready for priming and then final painting You may notice that I have cut the front part of the fuselage away, not really necessary to be honest, but I thought it might be easy for me when assembling the cockpit interior, I have added some internal details here as well, most of this will be hidden when its all closed up. The other end with plastic inserts From my previous post I mentioned I was casting the front of the engine intakes that I took a mould from the Anigrand kit, this shows complete and attached to the fans that i had 3D printed The other thing I was able to do, was to print the wheels on the 3D printer, all the dimensions for these were obtained from the Brooklands VC10 10 Link to comment Share on other sites More sharing options...

kev67 Posted July 30, 2015 Author Share Posted July 30, 2015 Small update, I have attached the nose of the VC10 onto the main fuselage and added strengthening struts from old sprue to give it some support, I will have to work out how much weight it will need to stop it from being a tail sitter. Once the interior is painted I can then close the 2 halves up, the windows will be cut out at a later date, it's just proving to me how big this aircraft is Tail section temporarily fitted 12 Link to comment Share on other sites More sharing options...
