I am not having much luck in getting my quad to fly maybe it is because I am a very inexperienced RC pilot. I must have I have done something wrong somewhere.
I am using a X525 V3 frame with the APM2 and was hoping that I could at least get to a controlled hover stage. I believe that I have constructed the Quad correctly but after arming it and with the gentlest amount of throttle it either wants to flip over – left side flips over to the right or when I have managed to get the quad off the ground it accelerates very quickly and shoots up into the air and then flips over and crashes. Yes I have broken a lot of props.
I cannot seem to get the Quad to slowly take off or even to hop it just seems to want to rapidly accelerate.
Here is some information on my configuration and my set up.
I have calibrated the ESCs manually and then automatically and have confirmed that they all are rotating in the correct direction
M1: Front Right spins CCW
M2: Left Rear spins CCW
M3: Front Left spins CW (pusher prop)
M4: Rear Right spins CW (pusher prop)
I believe that I have followed the instruction manual correctly including levelling the Quad and ensured that it is configured as X configuration, all appears to be working correctly within the Mission Planner.
I have adjusted the PIDs as per the guide Guide for flying a Quadcopter in Stabilize mode and for initial PID...
Angular Rate Control P = 0.8000
Stabilise Control P = 4.500
Yaw Angle Rate Control P= 0.150
Yaw Stabilisation Control P= 7.000
I would grateful for any assistance as this is driving me insane
Have you doubled checked that your board is placed right? The front side should be at the front side off the Quad.
Yes I have the board in the front top of the Quad, its overhangs the centre by about 5cm, I can move it back to almost centre of the Quad.
The last time i had this behaviour my board front was at the back of the quad. So the corrections off the software just made it worse. This sounds just like that. But if you are sure thats ok, then i cant help you any further.
Thanks Martin, Just in case I have moved the board to the centre of the Quad.
I had the same exact problem, than I realized that the board was not 'looking' forward.
Have a look at the arrows painted on the board: the 'roll' arrow should point forward.
Dean, you probably have, but lets double-check:
1. Have you manually calibrated all the ESC's individually?
2. Have both stage 1 and stage 2 HAND tests passed ok?
Yes I have manually calibrated all ESC's individually and then after that I calibrated them all automatically just to be sure, as per the manual.
Thanks for the suggestion, I am getting desperate.
And the results of the 2 hand tests?
Hello. Can you please confirm your Angular Rate Control P = 0.800 ?! If that's correct, you have it way too high. For your configuration maybe you want to try something like 0.120. The default value is 0.180 so if you have it at 0.800... that's about 4 times more than default. Confirm, correct if that's the case and try again.
What you describe happened to me maybe 3 times, I think it had to do with some corrupted data or parameters in memory. What I did was go into terminal mode, -> setup -> erase -> reset ! After this I re uploaded the firmware, done all the calibration procedure, radio calibration, level etc again, tuned the parameters and everything was ok.
Yes I have the Angular Rate Control P = 0.800
I will adjust this to 0.120 and follow your instructions, unfortunately this will have to wait until tomorrow before I will get a chance to test it.
Two more broken props latter ... I not having much luck,
I have erased and then reset, uploaded the 2.6 quad firmware and went through the whole process once again. I checked the programming of the ESCs using a Turnigy programming card and then calibrated them as per the Arducopter manual.
The motors arm ok but once again the quad just flips right over but this time left to right, it didn't get off the ground more than a foot before it was upside down with damaged props.
