Doug,

The exact same airframe. Vernon's is the only one that has had the problems. I had 2 kits and 2 sets of servos when his first set of 3421's failed (one at a time over Superman weekend) we swapped them out with servos I had for MY bobcat that was not built yet. But.... the setups are identical in both of our airplanes.

His plane has about 50-60 flights on the second set of servos.

The servos were all purchased at the same time.
