I saw the video. Wow it's really moving. I"m hoping when I have the balls to fly mine on 4S / 5S it's should be pretty fast. Question about the air speed meter? How accurate are these? Have they been tested in parallel with another system to valadate it's speed recordings? I also heard that the piot tubes have to be a certain distance and not to be installed near the nose but like 5" on the wing to get a good reading. I don't know just wondering. Not trying to disprove or approve just looking for a means that we could all come to some sort of aggreement on how to best record fastest Fj's accurately. I'be curious to know if you put the plane in your car while driving 100kmh, then stick the plane out the window or sunroof while holding onto it lol, and then took a measurment on the speed meter if it would also measure 100kmh? I don't know enough to even think if that would be a vaild test.
