I purchased a used Midwest AT-6 airframe with Robart retracts a few years ago and I’m finely getting around to working on it. This will be my first warbird, first gas engine and first retract plane. It’s also the largest plane I have ever had, so a lot of first in this one. I will not be doing the maiden flight on this one.
I will be installing a G-26 magneto engine the previous owner used a G-23. The radio equipment will be all new 2.4 GHz with 6v battery. I’m also installing a new fuel system. My plan is to get the plane in the air this year and see how it fly’s. If it fly’s well and I like it I’m going to strip it and redo it with some kind of covering and latex paint. I’ll also use a new canopy and cowl.
The previous owner installed a single flap on the outside of the center section of the wing. I’m not going to use this because other people are not having a problem flying this plane without flaps as long as the CG is correct. I fly at a very nice grass field with a long runway (
www.farviewflyers.net) so landing should not be a problem. The plane as it sets now without radio equipment or fuel system weighs 14lbs so I’m thinking flying weigh should be around 17lbs.
My first question is related to servos. I did not see a recommendation in the manual for servo torque for each control surface. I will be using two servos for the elevator one for each side. I normal use Hitec or Spektrum servos. So what size servos should I use for each Rudder, elevator and ailerons?
I’m going to replace the old golden rod linkage with new solid metal. Should I use 2-56 or 4-40?
Any suggestions or advice with this overhaul will be appreciated.
