Tail skid
Did you try the robart gear on your cub. I just fit it on mine. You said you had to give it down elevater to get it to recover from a spin, do you have the cg correct, that sounds like it maybe tail heavy. What engine and covering did you use. I am powering mine with a os46 fx with pitts and a 12-5 prop. I decided to go away from four cycles for this model. I am covering mine with solartex. The plane is framed up except for the wing panel which I will start this week. I have had many cub kits and this is far the best.
