I have my WKM Gains on a pot on my Futaba T14SG TX.
0 - 200% on the pot with 100% at the centre.
All been fine and Dandy.
I recently added Telemetry to my HerkulesIII and swapped out the WKM IMU V1 with a V2 at the same time (as i had the soldering iron out) and on the following test flights i see oscillation in the hover, it is quite gentle but an oscillation for sure.
This pronounced without the camera and gimbal payload.
So i am thinking that the FC is over correcting at the point where the sweet spot used to be on the pot at around the 150% mark.
Horizontal and vertical performance is stable and fine but when back in the hover it is good for around 30-45 Seconds then gets the wobbles, i can dial it out and now find the sweet spot seems to be at around 80% on the dial.
Nothing has changed in the TX settings as far as i can see and i am mainly flying in ATTI mode, although it also happens in GPS. I have not changed the WKM firmware at all and can't see why the HerkulessIII telemetry will have had this effect although it did require me to re program all of the motor locations, so i might be accusing a completely innocent component.
So my question is:
is the V2 IMU more sensitive than the V1 causing the FC to over correct.
I could just go with the new gain position but i would like to understand why this has changed.
Has anybody else seen increased sensitivity going from V1 to V2
many thanks...........
