Can anyone savvy here weigh in on how much having a two-axis rather than three-axis gimbal will affect the stability of the video, if at all?

- OrwellianChild 11y agoThe third axis would just provide the ability to pan the video without rotating the drone itself. With SPRITE's pod-style helicopter design, they may be able to use the counter-rotor to provide the third axis of rotation automatically.
- baddox 11y agoYes, the third axis is for yaw stability. While you certainly want that for professional aerial video, it's not at all necessary for these action sports products. Also, the aircraft can definitely yaw.
- codezero 11y agoBut this also ties the stability to the stability of the drone itself, if it had a third axis, that could be used to compensate for the drone stability, right?
- lsaferite 11y agoSince they are using coaxial blade and vectoring via cyclic control, stabilizing the camera on a third axis would be pointless. Worse really, it would be excess weight. The coaxial blades are used to rotate the aircraft around that third axis. The flight controller will just adjust the calculations needed to maintain the correct heading and the corect camera direction on the fly. The 2-axis stabilization is 'needed' to compensate for pitch/roll of the aircraft cause by the cyclic control of the blades. I've been pretty critical of UAV kickstarters, but I actually think this one is quite interesting and likely has a bright future.
- codezero 11y agoThanks! That's really helpful.
