I got one of these and it's just been bad. One of the motors won't spin (left rear), and another spins sometimes. I've re-calibrated it multiple times but no improvement. Also, one of the rubber feet fell off, and looking at the bottom of the pod, it looks like the reason it came off is that the plastic in that area cracked.
I've emailed the seller (BG) and they first said that they think the motor is bad (duh
!!) but I told them that I probably need a new body also to fix the foot.
These CG-022s seem to have gotten good reviews, but like I said, the one I got has been a major disappointment!
