Made a dolly out of a "U" shape piece of 4mm ply and foam blocks, foam supports at front and rear ( about where the vertical stabs are) the plane at rest sits at about a 10 degree angle
Used small control horns sticking up from foam blocks into large "Sullivan" exit guides in the wing close to the leading edge at the wing root, after 3 tries got it to fly. think i will need a third in the nose to stop the plane from wandering of the dolly, that accounts for two failed attempts.
Directional control of the dolly was done with a spare receiver on rudder Chanel,and a steerable nose wheel using independent power, I had some spare large diameter wheels laying round and the plane pushes the dolly easily to liftoff speed.
Overall it's a work in progress but shows promise, must confess to being surprised with the flight performance of the Skyfun, slows right down for landing and show a good turn of speed, though wants to climb as speed increases, think that has to do with the angle of the motor thrust line or CoG. I did take advice from someones post and made balsa elevons with pin hinges, btw using PVA is not recommended as it takes forever to dry ( something to do with the lack of air ?) I wound up using the toothpick method ( balsa pins so i could sand them flush ) and covered the gap while covering the wing.
