What Ive noticed so far.

Power wise its perfect. Hovers just under half throttle and the harriers are somewhere around a third or less.

Problems
This thing flown hard is pretty agressive. I hi-throws from hi-speed level flight you can pull into a hover and it will literaly stop right there and sit on its tail. Doing so tore a TP1320 pack loose. The velcro was fine but it pulled the covering off and tore it where it was mounted. That was a close one

If you do harrier landings the gear is kinda week. Touching the tail and chopping power is pretty hard on it. Doing so on pavement didnt seem to be a big deal. The grass just tends to grab it i think. Blipping the throttle just a tiny hair will put it into the air. Im taking the gear off hand launching is cake 1/3 throttle and 45* up and it will float away
