Good reccomendation on the motor.
Why the Fuse Mod?
The fuse mod protects the 4 in 1 from burning up. If you crash ( andyou will ) there is a good chance that the rotors will jam causing a HIGH amp draw from the motor.
The 4 in 1 is only rated to a max of 10 amps, and the motor will draw in excess of 15 amps and
FRY your 4 in 1.
Better to use the fuse mod and use up fuses instead of $40 4 in 1's
