Hi QQ. I flew my QQ190 for the first time in about a year the other day. Just been sitting on the shelf. When I arm my motors and select my usual flight mode (airmode/antigravity/horizon) and go to take off, the motors start to accelerate as normal, but then keep accelerating despite my throttle position. eg: if I aim to hover, it will start to hover then very rapidly keep accelerating skywards – the only solution is to drop my throttle to 0 or disarm the motors. I literally need to let it fall to the ground. This happens in all modes (acro, etc.). Prior to this, it flew like an F-16 on rails. I have recalibrated the ESC’s a dozen times, calibrated the accelerometer and re checked all other settings (PID’s etc). In desperation, I updated to the latest Betaflight Calibri_Race 3.5.0, tuned it (without issue) to fly as previous, hoping the upgrade might somehow solve the problem, not so – issue remains. I don’t think it’s the ESC’s as they calibrate fully and successfully on all motors, the motors are pretty much just slaves – could it be the FC signal to the ESC’s?? What confuses me, is that no changes or events happened to it between successful flying and this problem – just time on the shelf. Can I replace the FC in the powercube – could that be the issue. I’m assuming they are still sold and will just slot in place in the powercube – would rather not, but I can’t think what else could be causing this. Any advice much appreciated. Cheers. Jeremy
Hi Anthony. It’s been so long since I’ve been regularly using my QQ190, I’d forgotten how completely the re-set button actually “re-sets” (groan). Will need to go back in to calibration, try and find 5865- Band A channel 1 on my goggles and go through the RC cal procedure before I can make a call on whether or not that’s fixed it. Wish I’d noted my original band/channel as it performed so well around here. Never mind. Based on your comments, I feel it might just do it. I will report back for the record. Cheers.
