Thanks guys. At this point, I'm wondering how many of the glitches I've suffered have been caused by this.

I just need those becs to come in.

As for the 7XL on 4S, I can't even imagine (being new to the world of brushless buggies). Quite frankly, I'm starting to wonder whether the 3S with a 16T pinion might not be just right for the track. As it is now, it isn't super fast, but it gets to top speed in like 1.5 seconds. I'm still curious about how it's going to run on 4S. I'll have to see, because the smallest pinion that I can put on my setup is a 12T. Anything smaller and the can is hitting the rear support. I suppose a Feigo C model, or Neu is out of the question. Maybe I can ultimately get the new with the smooth can (although I read someplace that the screw hole locations are different on the smooth cans).

Thanks again.
