CMAN,

Here are some things I did to my PT40:

- Sport wing and rubber bands are the only way to go.
- I used wider and lighter fiberglass cloth because I didn't want an ugly hump on the wing.
- I used steel cable for the throttle and nose gear linkages. (You need a little soldering to stiffen up the cable but it's worth it!)
- I cut of the 'lip' of the tank hatch because it just got in the way when it was time to fuel up.

Things I wish I did to my PT40:

- Re route the nose gear cable so that replacing the quick link 'rubber disk' wouldn't be such a pain in the arse.

Good Luck and have fun! And don't sweat the small stuff!
