i changed the motor and it improved alittle if any. when i jab the throttle, the motor will usually stall. but now, when i just increase it gently, it'll still go. i don't have my tx with me here, i'll post my settings later. however, i really wish this tx has the delay function just like a 9c. right now, all the modes have to have about the same hovering stick position, or else it'll jump/pull itself toward the ground. and i still dont get what the lo. is on the revo setting? the lo and teh high has to be the same sign... that's all i know. i dont have another batt, wish i did though. can't afford it.
