RE: which cub??
Fact is.... both kits are mostly lots of sticks. They are both quality kits that will produce a good looking semi-scale Cub that flies great in a scale manner. The BUSA is a bit less expensive. Both offer plenty of opportunity for minor modifications to add as much/little scale features it requires to please you. Look at both and decide which stock features you like the most and how much additional work each will require to achieve whatever scale features you want most. I have the 1/4 BUSA Cub built mostly per plans with STITS lite covering, tapes, fake stitching and paints with a G23 up front. Not exactly scale... but it looks pretty good from 10' as well as in the air! Good luck!
NONY.... that is one fine looking Cub with floats!
