A friend just bought the hanger9 quarters scale j3 cub. I will be the one putting her together. I was wondering if anyone has built one of these and can tell me what gas motor they used. The kit recommends a Zenoha 20 but is this the best combo for this plane? I am interested in the fit under the cowl and the effect on cg when using a dle 20 or the Zenoha like the manual recommends.

If you add more power,more pitch ,and more prop length , will the same airframe become more twitchy and sensitive to fly?

How about some suggestions for flying glasses if you already wear prescription glasses?
