Is a push or a pull propeller better for a model airplane?
I’m going to attempt to make a design for a model airplane, then maybe try and build it. Most airplanes have a pull propeller (the propeller at the front of the plane pulling it forwards). However I have seen models with the propeller at the end, pushing the plane forwards. Which one would work better? Why? Thanks!

In general, if control and stability at all speeds are a preference to you in this particular design then you should choose a tractor driven (or pull) configuration. The benefit of a tractor prop is that it provides constant airflow over your control surfaces while the propeller is turning. This equates to have control, lift, and stability in a vary large range of forward airspeeds.
If your design is intended for high speed jet-like performance then a pusher prop is necessary. In a pusher configuration you can achieve more streamlined airframe construction and ultimately higher airspeeds. The downfall to this setup is you’ll only achieve lift, stability and control when the aircraft reaches a certain airspeed.
One setup isn’t any better than the other because they are intended for two completely different applications.
Good luck with your project.
