If you have all winter to build I would build the Kadet Senior. Your 46 engine will power it just fine. They fly smooth and are easier to see when you are flying higher learning to fly. The only drawback is hauling them to the field if you dont have a truck or van. If you do build the Kadet take some of the diheral out and add ailerons.
I like it, someone that thinks like me
I've been working on a Kadet Jr myself. This thing is a 48" spanned version of the MKII without ailerons or, at least it was. I've taken mine and made a couple of changes:
1) extended the wingspan from 48" to 54"
2) added barn door ailerons that are 3 bays wide and 25% chord deep
3) removed ALL THE DIHEDRAL
4) am installing a larger, counterbalanced split elevator and a taller, wider rudder that will extend to the bottom of the fuselage
I'm setting this plane up for floats so, in theory, the larger rudder will increase directional control on the water and the larger elevators will make controlling the aircraft's pitch easier with the additional length and weight of the floats. The dihedral, again in theory, won't be as required for stability due to the weight of the floats below the fuselage and, due to it's absence, won't fight the control of the ailerons
