Guys,
Just wanted to start a thread to understand when an Outrunner is user and when an Inrunner might be a better choice. Any ideas?

Usually, inrunners are used when high speed is required - as in EDFs. Outrunners have more torque. But this is not the Gospel truth. There will always be exceptions.

Another way people have looked at is that outrunners are more like "inrunners with gearboxes".

Also, if you are forced you mount the motor in such a way that the motor case touches the frame, then inrunners are the choice.  This is the case with some "flying wing" models.

I have also noticed that outrunners seemed to have more wattage per gram of motor weight. Is this generally true? does this have to do with the choice of inrunner vs outrunner?

So If the body of the motor touches the plane fuse(mounted), then inrunner to be used right? Why whether the outrunner produce any vibration?

And can anyone say exactly about the difference in using the inrunner and outrunner in the rcplanes?
