RE: Hobbico Sukhoi SU-31 ARF
I agree with the above, the landing gear needs a little extra attention, don't hold back with the epoxy. The plane flys well, just make sure that you are balanced slightly ahead of the recommended pt for the first flights, then move the CG back. I fly mine with an OS .61 fx and a 14x4w prop and get good performance, it is not 3-D. The covering leaves a little to bit behind,poor guality.
