Hidden Aileron Controls
I am building a 1/5 Scale Auster J1 Autocrat from a DB Models kit and have the following dilemma:
I wish to conceal all the Aileron and Flap controls, i.e. no external control horns. Everything must go inside the wing. I thought of Torque tubes running through the wing to the root, but in this aircraft, the root in the cabin area is totally exposed. In other words, no servos in the cabin area. I also intend to do a fully detailed cabin so Servos' there will be totally unacceptable. I am sure that this has been done many times before and I would like to get a few hints, suggestions, links to diagrams or modelers that have done this. Any help would be appreciated.
Thanks,
ir3

Hidden servos for Waco Bi-plane
Hello Bill:
Will that work for a Waco YMF-3 1/6 scale Bi-plane ?. The plans show just one servo for the four ailerons, but I think that will cause some slop, so I decided to install two servos for four ailerons (one servo for each wing). I hate to see the servos exposed in the bottom wings. Any advice appreciated. I have'nt started building, this is going to be a winter project, could be longer, not much in a hurry.
Thanks
Garthwood

I see no reason why it wouldn't work in your WACo, provided only that you pick servos that are both strong enough and thin enough to be fully enclosed. Then you can use scale links from the lower ailerons to the upper.
And servos in the lower wings will help the balance, and the wiring will be easy to conceal.
The one thing I will still do, though, is install doors for access.
Modern servos are very reliable, but the minute I have them fully enclosed some nasty little problem rears its head and I'm cutting into the wing. Having the door, making access trivial, I never have a problem. Murphy knows all.

PS: I also would not build that plane with only one aileron servo. wr.

Hidden Aileron servos
Hi Bill
Thanks for your reply. I will think about it. I was definitely going to have two servos installed. I'm surprised that Pica did'nt show the two servos option on their plans.
Regards
Garthwood

Garthwood:
Most of the Pica kits are old designs, when they were done few people would consider the great added expense of two aileron servos.
New designs almost all use double servos on the ailerons, the exceptions are mostly trainers and planes that are built as lightly as possible.
If Pica updates their planes I'm sure one of the first changes will be dual aileron servos.
