hi all,

yesterday i was flying my quadcopter in fpv when suddently crashed just going straight foward... like a plane on landing.

i was flying in alt-hold mode at about 9/10 meters, the firmware is 3.0.1 modified for hott telemetry, no problem before...

components:

tarot 650

motors 4822 390kv with 17" c/f (all props balanced with du-bro prop balancer)

APM2.5 with antivibration mount (the one 3dprinted)

fpv setup with minim-osd

battery 4s 6000

3691134152?profile=original

i have some vibrations, but when i switch in althold mode they increase mostrously... i can't understand

damaged the landing gear and 2 props...

from log i can understand that throttle out goes rapidly from 450/500 to 100 (minimum) but i dont know why...

i didnt have this problem before, no sync issue... i cant trust this machine if i don't find the problem...

did i do something wrong? could be a pilot error?

hope someone can help me understood what is happened

thankyou

cescu
