Ok, after flying a couple of times in a gym thats 50ft tall and over 300ft in width, im still having problems getting away from the walls lol. Im ok at flying the cp, but for some reason, the heli wants to spin left (nose left), i have trimmed the back rotor all it will go to correct this, but it still yaws left and its making it very difficult to fly, Is it suppose to do this, or is there any other trim or fix for this, thanks, !!!!?????!!!!oh, and is there a good site with better booms and fins for the cp?????
