I am almost finished my super aeromaster, will post pictures when done. I installed a servo in each wing, fit no problem. I plug each servo into the receiver separately, allows me to use flaprons. I also made my with ailerons on the top wing and increased the size of rudder and elevator. I have installed a 91FX sideways, waiting for my Bisson Pitts muffler to arrive. I hope it will be good 3d airplane Only thing left is to mount the top wing it seems to have far too much negative incidence, did you have any problems in that area?
