I've flown 3 Kadet Seniors, 2 of which were tail draggers. I personally like tail draggers. The major differences:

1) Tail draggers pull more to the left on take-off than nose wheel'd planes. Advance the throttle slowley on take off and feed in right rudder gradually to keep the plane straight. Practice taxiing on the ground with the wing off. (read about elevator on note 2).

2) Tail draggers can take hard landings better. On nose gear planes, the nose gear gets bent on every hard landing. Make sure mount the gear block in the right location. Look on the plans and draw a line at 15 degrees from the C.G. (towards the nose). Buy your wheels and gear, take measurements and put the mounting block so that the bottom of the wheels still lie on this line. If you move the wheels closer to the nose, the prop will be better protected, and it won't nose over in the grass as easy. Unfortunately, it will be easier to bounce the plane on landing and it will be harder to taxi. If you put the wheels to far to the rear of the plane, it will simply nose over too easy. Don't forget, you have to use the elevator on tail draggers. You need to hold full up elevator when you advance the throttle from a dead stop. Once the plane is rolling, you must gradually release the elevator. You can tell if you've released it enough because the nose will start going down. Don't let the nose go down too far. Keep this attitude and the plane should take off on it's own accord. If it doesn't add just a touch of up elevator.

3) The tail dragger will go through taller grass, of course, you will need to use the appropriate sized wheel (3.5" or larger). You can use the new light treaded wheels.

4) The one I flew had Four-Star 120 sized aluminum landing gear. You can use smaller gear (60 sized aluminum) if you are building the plane light.

5) If you build the plane as a tail dragger, it will help you practice for scale planes like a cub.
