I just got back from flying.
I have a
T REX 600.
I equipped it with a Pixhawk 4 mini a few weeks ago.
Since then, I’ve been around 10 flights with this TREX / Pixhawk. Problem-free.
For tuning, I put ATC_ANG_YAW_P on channel 6 so that I can set it.
After I finished setting I turned off channel 6. That was the only change in the parameters that I made before this last flight.
Today I wanted to fly again:
I increased the rotor speed.
The rotor speed was reached.
I slowly increased the grades from minus to positive. When I was about zero degrees, the helicopter jumped about a meter into the air and was immediately pushed back to the ground with full force. Everything happened in a fraction of a second.
Then I switched off the engine to be on the safe side.
The only damage that can be seen is that it has turned the tail rotor a little around its axis on the tail boom. all servos seem to be working normally.
I really doubt whether I can trust the FCs.
Here are the parameters and the log file.
I only saw that the RCIN shows input values that I have not entered myself. How can that be?
I’m very frustrated because I’ve bought and installed two FCs in the past few weeks.
Both are not working properly or I am making mistakes.
And our flying saw blades can also be dangerous when they react so unpredictably.
I hope you can help me.
