I have modified my Torrent with new motors and camera. It flies good most of the time. Left the PID settings as they were. Not a lot of oscillation or jitter, takes sharp turns and is pretty smooth. However, when doing a split-s, just as I am rolling to the upside down point, the quad suddenly makes a big movement back towards the start of the roll (maybe 30 degrees). It's a big enough jerk that I often lose orientation and crash. Seems to do straight out rolls just fine. Could that much correction be caused by high I-gain? Ideas? I-gain at Roll=57 and pitch=58. Thanks.
