There's quite a bit of slop, from the factory, between the pinion and tail gear. The teeth are close, but not touching. Is this about right, or do I need to snug it up? Is there a proper way to set the clearance?
Thanks, Mike
PS- You guys have been a big help, with my set-up. I appreciate it.

Allow a bit of free-play, proper term will be backlash between the 2 gears you're trying to mesh. too little and u'll be loosing efficiency and increasing wear, too much and u'll risk stripping/skipping. after a few trial and errors, u will get the hang of it.

I'm not sure which part of the helis u're refering to, but if it's the motor pinion to tail input gear, then you can adjust by loosening the 4 screws that clamp the boom on and shifting the boom back or forth to set the meshing. tighten up on the 4 scres when u're done

One common method of adjucting gear back-lash is to place a piece of paper between the gears and then adjust so no freeplay.
Once the paper is removed you have a nice back-lash.

Thanks guys. Yes it's the motor pinion to tail shaft gear that I'm referring to. I've used the paper technique on a couple of my nitro helis, and I wasn't sure if the same technique applied to the Shogun. Now that I know, I'll give it a try.
