R/C Groups - Aircraft Motor Prediction System   

Nice-looking calculator. You might have to insert your own values for newer cells, though. (I did not see any info on Lipoly cells.)

Anderson Park Flyers -- Electric Motor/Flight Calculator   

Last updated 2001, limited range of cells. The info comes from Motocalc and used with permission.

Electric Motor/Flight calculator   

Original calculator also used by the Anderson Park Flyers.

Simple Electric Motor Calculator   

A nice, simple calculator. Enter motor type or constants, gear ratio, prop pitch and diameter, and you get a list of rpm, power and efficiency for different voltages. Quick and easy for prop or gearbox selection.

Helicopter rotor speed predictor   

Choose from predefined motor, heli and cells, input your pinion teeth and calculate the rotor speed.

Glow to electric conversion Calculator   

Input the glow plane stats, and this gives you a guide to how much the converted plane should weigh.

Wing loading   

Calculates wing loading from wing dimensions.

Software and documents for heli flight   

A couple of spreadsheets for calculations for electric helicopters.

LCRC - Thrust Calc   

Static thrust calcs from empirical data.

Propeller Thrust Calculator   

Pick a prop from the list, select the type of input (RPM or Thrust), provide a value, and this calculator outputs the output (needed RPM or delivered thrust).

Plane Fun WebOCalc   

WebOCalc is a little JavaScript program that can help you design your next RC plane. Given the weights of various items and the wing dimensions, it can give you an idea how fast your plane will fly, and how much power it is going to have.
