RE: ESKY LAMA 4 THREAD
Hi Bill, Yes, the roll test will tell you if the shafts are turning true, rolling them on a flat surface such as glass (it's what I use). The "A" and "B" gears I'm referring to are the large plastic gears that are attached to the shafts. The gears you see on the motors are referred to as "pinions." Let me know how the roll test turns out.
Mike.
