That's pretty slow. Here, we can drive 75 on turnpikes. I think Texas has some 80mph highways now.Freeways allow 65mph
Freakin rocket ship!
Alright, here's the math. In 10 minutes you could get up to 3000meters at the p3's max ascent speed of 5m/s. A 1.28kg object would be traveling at 242.5m/s assuming no air resistance(if anyone wants to take a stab at terminal velocity that would be cool. Just a high school psychics student here[emoji4])the fastest you can go is to push the left stick all the way up for about 10 min without altitude limits...
then shut the motors off.... it takes about 2 minutes before you see the quad falling to earth.... the trick is to then restart the motors for the recovery.... don't ask me how I know this...
DO NOT try this in a parking lot of a crowded shopping mall..... ;-)
