I agree with "pim". The gun stabilizer can be omitted as the response time is too slow and it fails to achieve the desired effect. Perhaps other options like that posted in a previous thread ("Laregler" pitch controller from Germany) may be more realistic. Also, the stock tracks are very good and need not be upgraded. And yes, the hull-top machine gun completes the tank. The idler adjustment may be a sensible upgrade but I'm not sure about the suspension arms. I've got two of these 2A6's and both operate on stock suspensions with no problems so far.

Enjoy the build.
