need calculation formula to figure out what electric motor to use in a gas powered ai


well i guess th subject title says it all, basically im trying to figure out if there is a formula one would go by to figure out how big of an electric motor to use if someone where to be converting a would be gas powered airplane to an electric. Along with what factors play into the formula im sure weight and wing area plays a part in this.

i would also like to know how to figure in how many cells to use in the battery pack after youve figured out what size electric motor one would choose.

all help is appreceiated

I cannot complain!

That program will help you choose the best motor/battery/propeller combo for any airplane. Of course there are about a million of them!

What size is the plane and what is recommended for power?

After reading the links mentioned you should realize that normally this works the other way around unless you already own the motor.
