...Yes electric powered, pusher prop. 12X6 prop 14,000 rpm..13 pounds thrust..AUW 13.5 lbs. 57'' wing span, 85'' long
Hi, your Phantom II is awesome. Nice work indeed.
One thing that has me curious thou. How did you prove that a 12x6 at 14K rpm makes 13lbs thrust?

Thanks.
I havn't proved it yet. Scorpion calc is a motor/prop calculator that gives an estimate of performance, it comes out to 13 pounds thrust.
