RE: What engine should I use.
These numbers are from manufacture web sites or from distributors.
G-26 3.7 lbs 16x8 APC @ 8900
Fuji 32 3.7 lbs 2.2 hp @ 10,000 rpm 18x8 at 8,300 RPM (recommended by SIG)
F.P.E. 1.3 2.5 lbs Thrust: 10 lbs @7,400 rpm with 16x8 prop
Brison 2.4 2.75 lbs 21 lbs thrust
YW 24 2.3 lbs 16x8 prop spinning at 8400 RPM
Bye the numbers the YW and the F.P.E. looks mighty good.
