    Wow, nearly all the features I was looking for in one pretty compact package! I definitely like it!
    But, am I wrong, or main drive motors aren't synchronized? I care about this, because the only reason i see in subtractor is that it allows to run straight.
    Also I want to try using steering servo, built-in into RC receiver, to control steering motor via external PF switch. Maybe, I'll need to gear down servo output ~2:1 to provide enough torque.

    I think it needs some rubber track inserts! I will be trying something like this when my inserts arrive.
