I believe this is a FW introduced issue, also a lot of the P4's has got the very same symptoms.
My P4P also did this after upgrading to 1.5.600 but only at a certain RPM during in-decrease of motor speed like you do in the video, at some point the whole aircraft looked like was it made of jelly. The only difference i see, is that on mine it was like it was present on the diagonal of the white/silver props (rear left to front right) as far i could see yours was worst over the black ones, one thing to test is to change the props in steps and see if anything changes, i doubt it.
Ive got the same issue you've mentioned with instability at hover and also when landing. On start up of motor, the motors go through the momentary wind up for a split second and my P4P seems to want to rock slightly on its landing gear. when I take off and hover above ground it bobs around and drifts and is just unstable. In flight it's fine as far as I can tell. On landing, no matter how gently I land, when I try to turn the motors off with the stick down, the motors seem to wind up for a split second and I get the slight lift and have had a couple of tip overs. Its all been happening like this since the FW update and It's doing my head in! Have calibrated IMU on flat surface in different locations to make sure there is no interference, downgraded FW, updated again, done update to latest firmware with every single battery installed..... It's frustrating and Im concerned Im going to damage my P4P if it keeps drifting and doing the jelly wobble when it hovers and the tipping over the way it does on landing. |
