Took my TBS Disco clone out to the cricket ground right next to Sher-e-Punjab dhaba at Attur - about 15 kms from Hosakote toll gate for a maiden video flight. Camera used - GIT2P. Shot at 720p 120 fps & uploaded at 720P 60 fps.



Here are the details of the quad -

Frame - TBS Disco clone
FC - APM 2.6 with external GPS & Compass
Motors - EMax 980 kv
Props - Gemfan 1045
Lipo - 3S 5200 mAh
Gimbal - Banggood gimbal running SimpleBGC v 2.2b2

In circle mode, at one particular point in the arc, the quad shakes, corrects and sweeps the next 10 degrees or so faster that the rest of the circle. What could be the problem? Thanks in advance
