My P-51 has the 4130/16 in it with a 6s2p Tanic pack....5100 Mamp.........The previous Mustang I had was the same motor and ESC, but I used 24 GP3300 batteries to power it because of cost. It was 10lbs, 11 ounces and flew very nicely.........not as good as the 8lb, 8 ounce version that I have now with the Lipo power source, but it flew very well at the heavy weight..........It sure crashed hard though.......
P-51B, look at the video.

That is my 2nd flight.........It is a tame video due to having 12 to 15 mph winds during the flight and my camera man / editor got the "tame" sections of flight very well. My few aerobatic / speed sections, he couldn't keep up with the plane well enough for the video........
Complete setup: AXI 4130/16 , Hacker Master 77 3p opto ESC, UBEC, Tanic 6s2p pack 5100 mamps total, 16/10 APCe prop........Flys very scale and has plenty of power for my taste.........I get many compliments on it.
