229!! That 4.7x4.7 prop is what I ran on the funjet with 4s 2w-20 but only managed 125!! Must be slippery airframe and or extra rpm with the extra cell. About 68k rpm??, Have you tacked that sucker?

On board mini water cooled radiators next if air isn't good enough to keep the motor cool.!!

Ha, puffy lipo pushes the wings off.
