i just went to my lhs to get a main gear, but they've ran out of eflight 9t. so they gave me a e-sky 8t. i'm very well aware that the 9t will give higher headspeed, which is good for me since i'm doing mild 3d. but i think the 8t will give me more power as in torque, which should help as well since my headspeed decays very much when coming out of manurvers. i do have a 9t from my original motor, should i pull the 8t off and put the 9t on? or should i leave it with 8t?
