Thanks - will change my flight planning procedure and try again
The rudder movement might be that it went from CRUISE to VTOL
without a command (or a none standard command) and switching to QLOITER
over another CRUISE command ( very quickly) did not register properly.
I’m not sure what amp draw you are setting. My setup is very close to a V2 so here is a graph from my recent flight using a light camera payload up front (no mapping camera underneath).
During the “Hover” period, the plane was ascending. For FBWA, the ground speed was 20m/s.
Ok, I see now. On my setup, which is not an official V2, I am using a calibrated Mauch Power Module and that information comes with it to be entered into the BATT_AMP_PERVLT parameter via Mission Planner. In my case, BATT_AMP_PERVLT is set to 64.73156, BATT_VOLT_MULT is 10.00387, and BATT_CAPACITY to 10000.
The only V2 model I have params for is Gordon’s and it reads BATT_AMP_PERVLT is 48…which may just be a default setting.
Sorry It did not load on my post. Here is the Logs,
Nimbus had a broken wing and tail fin, which are repairable. It now works already. But I think there is an issue somewere when we test it on the ground.
The first thing I see is that the flight controller thinks it was commanded to CRUISE mode and then back to QLOITER at your 30 meter height. I have seen this issue make my Convergence VTOL crash as well. In my case, I accidentally changed flight modes incorrectly on the 6-position knob but APM Plane didn’t recover properly using v3.9.8 firmware.
Below, the blue is altitude, green and red are Roll and NavRoll respectively.
It was only 30secs during take off before the incident happens. My pilot was telling there was no input on. Nimbus maybe just around 100 mtrs away from the LZ.
It seems weird that it transition to cruise mode. The 2 Fmode on the switch should be FBWA.
50 long range flight for the nimbus was great already.
We were able to hover the NIMBUS V2. S1= Mavlink Telem has different approach on connection.It uses higher baudrate. System Motors Idle once arms. D16 Rc have the spring on the Throt. Expect it always in mid position. The funny thing is the RC was in MODE 1. It can be easily fixed if your a mode 2 flyer by going to Mapping Channel menu.
Motor power seems satisfying. Tricopter Tune was very stable in windy condition. Will try to maiden it in Fixedwing this coming weekend. Will let you know on the updates.
Thanks to Rolf’s (@Rolf ) suggestion, my SDP33 AS Sensor arrived today. I’ll be away on vacation this week but will install it and test it out on my Nimbus next week.
