I also have the Great Planes ARF and think it's great. I just spent the morning fixing it. My fault not theirs.
Be aware that you have to let this thing get up it a reasonable air speed on the grond before take off. DON'T let it try to fly on the angle of incidence because it won't for more than a few feet before it tip stalls.
I have a Saito 90Ts twin it it and everybody at the field stops what they're doing and sort of watches with their mouths open.
