It would appear that there is no "room" in PWM signal size for the stabilization corrections when pilot is commanding full throttle.

As ESCs are calibrated for 1000-2000us PWM range, and pilot is commanding about 1970-2000us throttle (which is 100% duty cycle), there is no space left for the flight corrections from the flight software, which will result in UAV flying "uncontrollably" without pilot flight adjustments and without build in stabilization routines.

This could result in a very nasty injury or hardware/property damage while pushing UAV to its speed limits.

Needs to be looked into and fixed ASAP

throttle correction on commands removed

throttle limitation to avoid loss of control (see issue cTn-dev#3 from cTn-dev), seems to work this time (has cost some propellers)
