For tail draggers, the wheels are generally set so that that they are even with the leading edge of the wing.

An easier solution is to purch a Fults strut nose gear. This unit will solve all of your problems. Your plan will handle better on the ground and can hold up to the mose severe abuse. I hade the same problem with my trainer and the Fults strut was a much easier solution than converting to a tail dragger and re-learning how to take off and ground handle.

Fults you should be available at your LHS. If not, Tower carries them also.
