My 6" Tri-prop beast recently gained a 3D Aeropod with a jumpseat for GoPro, and adjustable FPV angle, so I decided to play around with it and see how it flies at maximum (60°) tilt... See for yourself the results!
I used a couple of different props in the various clips - GF6040bn & HQ6x4.5x3CFN. The CM2208/2000 motors drive them both pretty nicely, but the carbon infused HQs have the edge in raw power, speed, and smoothness. Need some more tuning to get the Gemfans smooth and they do lack power a little, but they're ok as a cheap alternative!
