Well it has been awhile since I had a large foam board jet so I constructed a new F-22 Megajet. It has a 40" wingspan and is 56" in length. This time I put the Turnigy 3648-1450KV motor in it. I'm currently using a 60 amp Exceed ESC, 7X4.5 TGS prop and using 2 SkyLipo 3300 mah 3S 40C batteries connected in series to provide 6S voltage.
I have now flown it 3 times and am getting about 5 minutes fly time using some throttle control. I am currently limiting WOT runs due to the fact that when I static tested the motor it was pulling 106 amps at WOT. Not exactly sure why I am getting this high of an amp draw since I used the same exact combination on my XF-18 and it pulled only 70 amps a few months back.
Thinking about dropping back to a 4S battery combination hooked up in parallel so I can increase the prop diameter. Previous Megajet handling characteristics where much greater using a 9X7.5" prop on an 960KV motor. Liked being able to hover and hold high alpha without using high revs.
