Scale Calculations equal to 1:1

[SpeedAssault]

Just about finished my 1/5 Brushless CC2200 6s 30c lipo
total reduction 11.5
motor spd 47256 RPM
calculated speed 60.72 MPH


Axle torque 4.45
motor power 3.5 HP

Brians Calculator is awesome http://www.scriptasylum.com/rc_speed/_units.html

What is the calculation for these: what does
3.5 HP in 1/5 scale convert to in 1:1 scale
and 4.45 ft-lbs

thanks
