In the last couple of months I have utterly destroyed two Bixlers. Needless to say I need some advice.
The last crash went like this. The auto mode was set up to fly a trip around the ball park at an altitue of 60 meters (approx. 200ft). When I put the plane in auto mode on the ground the prop went spinning and she took of in a head wind. Then the plane climbed to an altitude of maybe 5 meters (approx. 16 ft) and headed for waypoint 1. The altitude remaind way too low and the turns where way to wide. About 300 meters (approx. 1000ft) wide! Given the low altitude and the wide wide turns the plane eventually found a tree and exploded into pieces. Luckily I was able to recover most of the expensive parts.
My two main questions are:
I really hope you people can help me because I have destroyed two Bixlers and would rather not have this happen a third time in a row.
Thanks in advance.
One additional remark: the Arduplane seemed to respond sluggish to keeop the plane level. When I had the plane in my hand before flight I noticed the sluggish movement of the servos like the Ardupilot was giving just a little bit of input.
Thank you for your help. I have bought a new Bix3 and will try this.

I have to ask, have you done test flights in FBW-A and Loiter? At what angle does the plane climb in FBW-A with at 80% throttle and holding full up pitch? Are all your control surfaces moving the right amount? What amount of elevator up/down is recommended?
Have you also done an autotune?
In your log the pitch lags behind and below the desired pitch, towards the end requesting 15-17° and getting 4-6°.
