Cliff Bastow Posted November 27, 2023 Share Posted November 27, 2023 I purchased this JU52 today and would like to know what make it is, Any ideas please? I thought it maybe VQ but having downloaded the manual I now dont think it is as the VQ one has a large hatch on the top and this one has a solid fuselage top.

Robin Colbourne Posted November 27, 2023 Share Posted November 27, 2023 (edited) Cliff, can you give us some clues please? The wingspan, construction, power (IC/Electric/Brushed/Brushless) plus some shots of the internals and undercarriage will all help the sleuths on here. This VMAR one looks a possibility. If you go to the link and click on the arrow to the right of the righthand picture, you can see more shots of the model in the military colour scheme. I suspect the EADS colour scheme was chosen as it is German and military but without the fin swastika that wartime colour schemes would have had.

leccyflyer Posted November 27, 2023 Share Posted November 27, 2023 (edited) As Robin said it's the VMAR Tante Ju. This is mine - a lovely flier on just a modest 3s1p 2200mah pack. Edited November 27, 2023 by leccyflyer 2 Quote Link to comment Share on other sites More sharing options...
Cliff Bastow Posted November 27, 2023 Author Share Posted November 27, 2023 That certainly looks like it and the colour scheme is the same, but if it is someone has modified the ailerons to a more usual style! In that case Leccyflier what is the correct CG please and also are the outer motors correct as they have a distinct outwards thrust line? The wingspan is about 1.6m Quote Link to comment Share on other sites More sharing options...
leccyflyer Posted November 27, 2023 Share Posted November 27, 2023 The CG on mine is as per the manual, but that's out in the workshop, so I'll check tomorrow. The engine thrust lines do indeed look a bit alarming, but that is how they are made and the model handles beautifully. The blue anodised clevises and ply offset hinges are exactly as on my flaps, but as you said it looks as though someone has rehinged the ailerons, so that they are not cranked below the wing. I can scan the manual if you like. Quote Link to comment Share on other sites More sharing options...

That is correct. It helps with the engine out condition on the full size. The Short Sunderland is another multi engine aircraft upon which this is very noticeable.

Robin Colbourne Posted November 28, 2023 Share Posted November 28, 2023 The outward thrustlines are just about perceptible in this picture too: Quote Link to comment Share on other sites More sharing options...
Andy Stephenson Posted November 28, 2023 Share Posted November 28, 2023 Are the outward thrust lines to counteract the loss of power from the engine on the other side? It looks like it might have some effect. Quote Link to comment Share on other sites More sharing options...

It looks like it might have some effect. Andy, the loss of thrust and the drag from an engine which is now acting solely as an airbrake. It is one of the reasons that aircraft need such large fins and rudders, as the rudder must create enough yaw into towards the good engine to maintain straight and level flight. In turn, holding on that rudder creates drag, which requires more thrust and more rudder. At least the Junkers Ju-52 could go to max power on the centreline engine and just enough to maintain height on the remaining one. The Gloster Meteor, and to a lesser extent the English Electric Canberra, were notorious for requiring so much rudder when flying on one engine that many pilots simply didn't have sufficient strength to hold the aircraft straight.

leccyflyer Posted November 28, 2023 Share Posted November 28, 2023 As requested the CG as per the manual is from 90mm to 95mm back from the leading edge measured at the leading edge of the wing at the wing root. Control throws are as shown on the image below. If you like I can include the whole 16 page manual, but it will need to be put into a PDF really. Just let me know.
