Mostly curious. Why do you want to change it? What issue is the nose gear causing?

My trainer, a Great Planes PT-60, was designed to use a nose gear but we built it as a tail dragger because of a specific issue. I had an ARF trainer and a PT-60 with nose gear. I have a really bad tendency to drop the nose of the plane just before touch down. I've broken a firewall, and damaged the bottom of both fuselages, because of this. With the new PT-60, the worst damage has been a broken prop. Usually the worst is that it stops the engine when the prop touches the ground.

The right answer, in my case, is to learn to land. But, changing the configuration of the plane has reduced the amount of repairs needed while I learn.

Here is a drawing of the way mine was done. Everyone says "the gear has to go in front of the wing" but my plane works fine with the gear slightly behind the leading edge.
