[QUOTE="Dronason, post: 10403, member: 553"] At first, the compass seems to work nice when in flight at some altitude. [ATTACH=full]1015[/ATTACH] for flight at some altitude [ATTACH]1014[/ATTACH] When you were in Sport mode (before the crash), you first were full elevator forward, speed increased up to 9 m/s. You started to release the elevator and at same time put rudder to maximum. So at same time it was braking it had to rotate it reached a pitch angle of 65° and roll angle of 73°. [ATTACH=full]1017[/ATTACH] The Right Back motor get's to its maximum and was not able to give more. [ATTACH=full]1018[/ATTACH] [ATTACH=full]1016[/ATTACH] So I would say that IMO that you discover where are the flight limit in sport mode. There is an indicator (where there is the compas) that show the % of power used by the Spark. You probably reached 100% with your brake and rotate moves and the Spark flight controller was no more able to keep it under control resulting in a ground crash. At a point it was upside down and the motors stopped. Maybe there will be a better flight analyst than me that could check it too but from the flight record, there was no issue with the battery, GPS, RC or the compass. It seems that the Spark is not pilot proof in Sport mode against very aggressive flight move. We need volunteer to test it :) [/QUOTE]
