[QUOTE="STEMDrones, post: 99073, member: 18779"] We tucked it far enough back on the battery that the downward IR transmitter&receiver have a clear shot of the ground for a fairly good angle, and it's nowhere near the camera. So I think the answer is no, although if the IR emitter casts a wide flood, perhaps some could be reflecting off the payload? But should that make it spin? Doesn't feel like it should, but that's why I'm posting here. I'm sure I'm missing something, and there's lots of experience in this forum. I was afraid since I sat the payload further back (to avoid blocking the IR sensors) it would throw off the CG, but that doesn't seem to tip it or otherwise affect it, except for the spin, which wouldn't be CG-based. Other theory - since it's held on by (strong) Velcro, there's a TINY bit of freedom for the mechanism to slide around. Could that momentum-lag be confusing the gyroscope? Does everything have to be totally rigid? Again, doesn't feel like the likely culprit. [/QUOTE]
