Min RPM to make a aerial vehicle

[michael jorden]

What should be the minimum RPM of the motor to make a small wooden board based circuit fly??

i think you are trying to make circuit that can fly like a helicoptor. many factors affect to make that circuit fly. rpm of motor, weight of circuit, diameter of propeller also balancing of circuit is great problem as change in torque of motor or wind can imbalance it. it is difficult to make this type of project. some type of gyro mechanism is required to balance it. balsa is lightest wood. search for rc helicoptor motor rpm to get some idea. rpm can be increased by gear mechanism.

Hi Michael,

RPM is not the only thing that you should take care of. The weight to power ratio of the motor is more important. You can increase the RPM several times using a gear mechanism provided that the motor should have enough power to run at normal speed with that gear setup. 

Inshort you need a motor that has lot of power and reasonably small weight.
