best way to keep the MM from starting to swing and eventually crash is to be as gentle as possible on the sticks. the quicker you try to make it move, the quicker it'll get out of shape. when i go to forward flight, i push up on the stick just about as slowly as i can untill i'm at full throttle, i'm also controlling the yaw at the same time as thats when it really can get hairy.

RC18, i'd be willing to bet you could return the rotors and save yourself the 10 bucks. these things seem almost indestructable, they're just so small. as for the motor, it could very well be going bad, coreless motors can vary a lot from one to another so one could be great and the next could barely work. i also found out that the motors in the MM are customs, stronger magnets, longer lasting brushes, ect. its kind of a bummer cause thats what they did with the bigger BRs and their N20 motors. they would burn out and replacements wernt always cheap and you could only use that one kind. i havent heard anything in the way of replacement parts either. they should last a while, but it might take some hunting to find a replacement.

if you do oil the motor, use as little oil as possible, just a tiny drop on the shaft where it goes through the brass bushing. too much and it could get inside the motor and do some damage. i use liquid graphite for all my lubing, its non conductive and it doesnt hurt any type of plastic or metals, works pretty good too.
