humveecrusher,
Here's the trick that I use to set my gear mesh. Cut a strip of paper about 1/4" wide by a few inches long. Loosen up the motor screws, place the strip between the gears and turn the main gear to thread it between the main and the pinion. Now push the pinion against the main and tighten down the screws.
I got that trick from the Protech Shogun manual, but I've seen people recommend it on the forums. Gives you a nice backlash. If your gear mesh is to tight you'll fry motors.
Thanks rbiasi. I do this on my other rc's but wasn't sure if this is a normal sound right out of the box. It does seem that the mesh might be to tight, thus the whining sound as the rotor comes to a stop. I'll check it. Right now I can't get it off of the ground with my 8.4 V NiMH. I'm not sure if it is because my battery is shot, if the gear mesh is to tight, or both. I have read that the NiMH will get it up 5 feet or so but I can't even get it off of the ground at this point.
