RE: UM Corsair problem
ok so i got mine out today and got to looking at it.. it has the same motor as the sokhoi.. so i put the replacement prop that i had for my sokhoi on the corsair.. MADE A GOOD IMPROVMENT ON POWER!!!!!!! still no power house but definatly made it worth flying.. i did notice it prefers no wind and full throttle is a must for the whole flight for fun so flights are short. the champ has the same prop as the sokhoi if you got one of them laying around. give it a try you wont be sorry!!!!!
