I still have no use for any obstacle avoidance. I've never used it and I removed the RealSense from the H Plus.Obstacle avoidance is important for any drone operator.
If it was climbing it was because the throttle stick wasn't sitting at zero. Either the stick had oxidation (common when in storage) or the stick calibration wasn't correct.the first problem that I had encountered is that H+ would ascend, without throttle input.
I agree that on very hot days when flying with a bright sun there can be sufficient heat build up to cause problems with the GPS and/or the Flight Controller. The dark color of the H helps with visibility and protects the plastic from ultraviolet degradation, but it also adds solar gain. For those who must fly in those conditions, relocation or ventilation are beneficial.I along with a few others, as proven that by relocating the GPS/Compass is beneficial.
Perhaps that is related to the buffering capacity of the camera.There is no reason the C23 is not capable of snapping photos at 3 second intervals.
