Cub: high lift wing, slow/stable plane… its not really meant to have a lot of power. I'm going to be devil's advocate and say the 10GX is probably fine for scale cub like flight. If you want to hover go with the DLE20… though I think thats silly, our 1/4 scale cub had a 4 stroke 1.20 in it and that was overpowered… .60 size cub with a 20 would be…. well…..it would be fun, but not very cub-like.
