Quote from: ched on Sunday,September 01, 2019, 18:47:39 I assume you have calibrated the gyros etc?
Quote from: ched on Sunday,September 01, 2019, 18:47:39 Is fc soft mounted? Vibrations could be causing twitches.
Quote from: ched on Sunday,September 01, 2019, 18:47:39 Ensure all motors seem smooth when rotated, change props?
Quote from: ched on Sunday,September 01, 2019, 18:47:39 Any chance of BB logs?
Quote from: ched on Sunday,September 01, 2019, 18:47:39 Are you running airmode?
Quote from: ched on Sunday,September 01, 2019, 18:47:39 Is the idle set too high, too low?
Quote from: ched on Sunday,September 01, 2019, 18:47:39 All bolts tight, check all connections (esc, motors etc).Does the FC show drift in BetaFlight on the bench?
Quote from: ched on Sunday,September 01, 2019, 20:17:43 Reason I mentioned props was vibration. Random twitches could be some sort of throttle induced vibration.If it's not drifting on the bench then it seems like it's an issue with vibrations. In Angle / Horizon mode Accelerometer and gyro sensors are used but only gyro sensors are used in rate mode.So if it's not having issues in rate mode then it could be the accelerometer?
Quote from: ched on Sunday,September 01, 2019, 22:42:39 OK so sounds like it could be gyro noise, that's all I can think of at moment.I assume no cables jammed under FC or stack bypassing the vibration rubbers?One weird thing I had a couple of years ago was one of the potentiometers was wearing out and used to give out iffy signals when it felt like it. This gave some very weird flight characteristics Maybe recalibrate tx and rx.I assume all esc are running same FW as you said you had a replacement? Not just same FW but same settings although I doubt that would effect things. Clutching at straws.Which version of BF are you running as some had issues with version 4 and the D term being too high by default?Change loops to 4K 4K, turn on dynamic filtering. Maybe change the D term low pass filter maybe up or down 10 units?
Quote from: AmiSMB on Tuesday,September 03, 2019, 14:58:44 I have taken a look at the spec of the Tyro109 and the problem will be the sensor used which is the ICM20602 and it is notorious for being very picky on how it is mounted. I remember that I mounted an FC, Matek F405-AIO, with this sensor on on one of my KC250 frames and on the maiden it freaked out. I ended up putting it on these damper mounts. This video shows the issue very well
Quote from: ched on Tuesday,September 10, 2019, 16:02:51 Looks like it's flying well. Well done for sorting it.That was a close shave early in first video!!!!
Quote from: ched on Wednesday,September 11, 2019, 13:29:26 Sugar.I am surprised the esc took out the fc. I thought the tyro109 had the power straight to the esc. I could understand it if there was a short on the esc if power went through the fc and it could pull too much current and blow a track. Are you 100% that the fc is dead? I assume it's powered from esc? Could you unplug the esc from fc and try usb to see if fc is ok?
Quote from: dp106 on Wednesday,September 11, 2019, 13:34:54 Yeah I plugged it in to usb on the computer. LED did not come on and the board started heating up very quickly. I think I must have shorted something on the ESC and it sent too much through to the FC
