RE: recommendations for low wing trainer
If you are comfortable with GWS electrics, the Formosa is hard to beat. It should fly OK on the stock motor if you keep it light or you can put in a 100 to 150W brushless.
Just make sure you get the fuselage straight, fix the torque rods to the ailerons well and make sure the canopy piece does not fall off during flight.
It is a predictable flyer but definitely not self-correcting like the E-Starter.
