If I am not then this is my question: What is the horsepower motor needed to drive 2 blades x 1 meter diameter aircraft propeller? It doesn't have to be 100% accurate on your answer as long the estimation is close enough. This is rather for general knowledge than for a specific project. I will appreciate any honest input. If this kind of question is on the wrong spot please redirect to the right place.

Errrr, I'm guessing you are in the wrong place,but I have no idea where best to direct you to!!! So sorry!!

I wonder what the link he will post will be. Hmmmmm maybe some sort of gambling site with a nic like bid again to win.

This is not enough information to do this calculation. How much does the aircraft weigh? how much resistance torque does the propeller need to overcome, what is the maximum velocity that you expect the propeller to rotate at and what maximum speed do you need your aircraft to fly?
