The only tip I have is to connect the two wing pieces for each side in the plan, easier to cut put two pieces rather than 4 and glue them together and scale the wings up 115 or so percent width wise. Also what is up with the wierd kfm step on the wing, why not a normal one?I imagined it would be difficult at that scale because some of the parts proprtional to the thickness of the foam (3/16 in) would be scaled down. However, you still managed to put it together at 45% which is pretty impressive. I am glad it works! I imagine the full scale version should be easy to put together but I am not sure if I can make it right now since I am in an area where I can’t buy foam.
