Wow, My first tank - a Panzer III has arrived. Looks good, feels hefty in the hands.

Upon opening up, I noticed that quality not as high as I expected:
+ Left idler wheel is misaligned
+ L front suspension bracket was not fully inserted into holes on the hull
+ Remote controll looks very cheap, battery compartment is tooo tight - I use varta low-discharge NiMh 2100 mAh and they barely fit even though they're not very fat, 2 cells were damaged when I tried to push them in place. The battery cover could not close entirely.

Antenna of my Panzer III is at the back (I saw some photos of othe panzer III and they seem to have the antenna at the side?)

Some questions:
- When I turn on the tank with no load and the RC at the lowest speed, the two motors run at the reverse direction. So how do I break in the gearbox? As the FAQ says run forward 1 hour, backward 1 hour, then forward 1 hour again. How do I get it run forward?
- The teeth of the gear on motor axle (both sides) do not perfectly align with the first gear, does that matter? if it does how do I adjust them?
