Replace the Air Core with a decent trainer like the Sig LT-40, Avistar, Superstar, or the Eagle 2.

With any of the above airplanes, you won't need wheels, wheel collars, or a spinner.

Replace the engine with a Thunder Tiger Pro .46 (my choice) or an O.S. .46 FX... Change the prop to an 11x5 Master Airscrew and try two of those to start with...After learning, you can switch over to APC props.

The wood ones are just too dang fragile and will break just from trying to start them. They are not real efficient either and you will lose a lot fo power.

With a couple changes, you will have the perfect setup.
