Never felt that at all. Hey, we all tend to push products beyond their limits and I'm one of the worst offenders.
I just did some searching on that 2204 motor that your using. 138 watts on a 6x3 prop! That means your hauling that little bird around with well over 250 watts per pound!
I've over powered some planes before but never even close to that point. I wouldn't make any sudden control surface inputs at full speed without expecting it to fold the wing and/or rip off tail feathers. It should be a rocket in straight and level flight though. Again, I can't wait for the (uneventful) full throttle video. It should be quite thrilling.
