I have a new ZMR250 FPV quad. I got it all built with these components:
4 - Sunnysky 2207-2100kv motors
4 - Afro 20amp esc's flashed with blheli
Acro Naze32
Spektrum satellite rx
6x4 HQ Bullnose props (also have some regular 6x4 HQ props)
Bluetooth module (not yet installed)
Mobius Actioncam
5.8ghz ImmersionRC vtx with VAS Dura-Spec 5.8ghz LHCP antenna
VAS 3 turn helical 5.8ghz LHCP antenna on the vrx
ImmersionRC UNO vrx
Fatshark Dominators
After setting up the Naze32 and calibrating the esc's, I went into the backyard for the first test hover. The ZMR250 sprung off the ground into a very nice hover, requiring very little stick input to hover in place. It's very stable and I was very happy to have this thing hover so easily. Then I tried a vertical punchout...hmmm, not so happy now. The quad yaws clockwise in a punchout and then stops yawing when I come back off the throttle. I get the quad back to a "tail in" orientation and try to punchout again.....it yaws clockwise again. Hmmm, set it down and unplug it.
I began thinking that "perhaps" the esc's didn't actually fully calibrate...kind of a "shot in the dark" but it's a thought. I go back to my computer, remove the props (safety first), and I get back into Cleanflight (latest stable version) and I calibrate the esc's again. Put the props back on and head back outside. Back into a nice stable hover, just as i saw before, and then try a punch out.....it yaws clockwise. Very odd!
Would any of you quad guys know how to resolve this unwanted yaw action on punchouts?
