I have built my simple cub as a 3 channel to start out. Does anyone have recommendations regarding landing gear wire for this? I have tried the 4mm stuff for the storch and that was a little big to handle and I don't think it is needed for the smaller plane like this simple cub. This is my third plane cutting out from the pattern onto my own foam board and I still find myself going through on the edges where you peel the foam away to cover the exposed foam on the edges. Any suggestions on how to prevent this or is this something that will just get better with time?
