Hello everyone,

I'm new to rc projects and I am starting a project to build an airboat. It is going to be around 2 feet long and 1 foot wide. I decided chose my motor and propeller and wanted to make sure that the motor shaft fits into the propeller hole. How can I tell if it fits or not.

This is the propeller I am getting:

This is the motor I am getting:

Thank you very much.

You really need to do some reading on boat power systems before starting this. That motor is meant to run a geared system, hence the extremely high RPM. Plenty of these boats have been built before, so start with a known good setup and then get creative if you want to.
