[QUOTE="Ted Schoenfelder, post: 52217, member: 7687"] Yes, initially. But since you mention it, I will try another IMU calibration. However, I regularly check both compass and IMU before each flight and they consistently show green. I generally don't see IMU warning messages. Warning messages I do observe tend to refer more to some element of motor performance. Nevertheless, I will give re-calibration a try. I built three of my own home built float gear versions in an attempt to alleviate performance problems. Generally they reduced weight by about half, but it seems like weight is not the issue (see stats below)? Here is an example of one design that weighed about 30 grams in contrast to 65 grams for the ball floats (see pic below). However, it was unstable in flight and had similar performance problems. By the way, if curious, those are the finger guards DJI has on their web site and on the far side is my tracking device (a Marco Polo) with the antenna pointing aft, these two combined weigh an additional 20 grams: [ATTACH=full]5248[/ATTACH] [ATTACH=full]5249[/ATTACH] My own designs, in spite of being lighter, were less stable so I went back to the foam ball version. However, the unreliable performance of the ball floats is not satisfactory. I want to be able to have confidence the aircraft will perform consistently with the float gear mounted. If I am not using floats, I fly the configuration below (gear weighs 50 g.) and with the finger guards and tracker is a total of 70 g. This is right between the weight of the foam balls (total of 85 g.), and my home made gear (total of 50 g.). I have no performance issues with this configuration, which puzzles me! It seems obvious my performance issues with the ball floats is not weight related. It could be an aerodynamic issue, or what I'm beginning to suspect, possibly a motor issue?
