Ok just came back from my LHS and when I told the guy what it was doing he imediatly said new motor. He said he replaces brushed motors every month...Wow
It was too late to fly when I got home so I'll try tomarrow. The new motor has a 10t pinion on it but my old has a 9T. Does this matter? How will it affect motor wair and performance?
For DD I just used my old (stock) mount. Much stronger than the others. All you have to do is cut out the flat part and there you go a new DD mount.
Thanks,
Justin
i hear the main motors are supposed to be good for ~25hrs of use. not sure if you got that much, but once a month sounds good. a 10T pinion is meant for symmetrical blades, 9T is for flat bottoms. 10T with flat bottoms will overheat and have short flight times, 9T with symmetricals will have inadequate rpm/lift.
justin is also right about the dd mount (brain fart). the stock tail works best, you just have to install it as a pusher instead (prop on rhs pushing on the motor instead of pulling it). instead of grinding the mount to fit, all i did was slot the screw holes a little with an x-acto knife to get it to fit.
