Well guys..

I wish I could give you a definitive answer at this point.. but I can't. JR has been looking at the problem and hasn't found anything yet. Things are still being looked at though so I can't speculate on what might be happening. I DO know that BVM has suggested people go to the 9411 instead.

The 3421 that burned up on Harley's Bobcat was looked at recently by JR and JR Japan asked to see the servo to further analyze the problem.

Personally, I think the 3421 is a fine servo, but might not be up to handling the demands of a gyro on high gain. I'm still hoping JR can find the cause of the burn out.
