Just put together a stock Zoom 400. Everything set up as per the manual. First flight some funny grinding noises after a minute or so.
On inspection both small gears at each end of the tail drive have shed their teeth. It just looks like they have been ground away. Not happy!

Did you get the gear spacing right? I damaged one of mine in the process of fitting a brushless motor, but once I spaced the gears correctly it runs perfectly, its not the quietest of geartrains but seems to work well enough.

Good luck in finding replacement gears.

Got new gears from Mat Watkin (cheers Mat) through Revolution Helicopters in Altrincham who have been very helpful. Set up and away we go with no further problems. Flies great, watch out for the protech gyro its shown the wrong way up in the manual, well mine was. Flown about five batteries worth and all was going great until I started doing piro`s in the lounge now I need a set of main blades. OOps!

I munched my tail gears when setting up the heli also. Stupid me, I had the brake on the speed control active. --- Stick to low, CRUNCH! -- Once I got that straightened out, I haven't had any problems.

Good luck getting it sorted out. Sounds like maybe your gears didn't quite have the right lash set.

If you are using a motor with a 2mm dirve shaft you could use 2 of the pinions off the humming bird, aerohawk, and most of the micro helis. all of the stock 370 motors on these helis use a 10 tooth 48p 2mm pinion. Hope this helps.
