my little Twister 400 sport is having some problems currently, it spins, i have adjusted the trim and gyro settings and cant counter the spin, as i start to counter the spin it starts to spin in the opposite direction. it has only had 1 crash and after that it was flying perfectly. a few flights later it developed this problem, the tail motor works fine and i have switched the tail rotor over to a brand new on thinking that might be broken somhow, any surgestions??
