Momentum theory - Wikipedia, the free encyclopedia If you are after flight times, they are linear in prop diameter and proportional to 1/mass^1.5. So, lose some weight and increase prop diameter. You can probably do that with stock motors. IIRC a fair amount of weight can be saved by dremeling...

I tested the absorbers that I evaluated for Solo. If you're planning on using an absorber, 3DR is selling the correct one, but it is still a half-measure. I don't know what to tell you here. What were you looking at in u-center? Did you have a control? Was the GoPro recording? Was the GoPro...

Did you connect uBlox uCenter and compare the reported signal-to-noise level for a selected satellite and/or the reported speed accuracy with that of a control GPS? I hope not. In my testing, combinations of foil tape and absorber performed worse than absorber alone.

FYI, the GoPro in the gimbal reduces the signal-to-noise ratio reported by the GPS by around 12dB. Adding the RF absorber that 3DR is selling attenuates that noise by about 6dB. If you wrap the GoPro in a faraday cage (like this: Shielding a GoPro's EMI / RF Noise - Hovership) you will eliminate...

It's probably more like the RF signal chain is better designed. The M8N is known to present a tradeoff: it is a dual-band GPS, which means it has to have a wider-band RF frontend. This means it will be more susceptible to noise than the 7N. GoPro is known to be noisy. You might find that doing...

Making sure the antenna pin is not touching the shield is a good idea. You might also find that shielding the source of the GPS noise is very effective: Shielding a GoPro's EMI / RF Noise - Hovership
