I just finished one and I don't think its a good candidate for conversion. One beef I have with the T-Craft is the landing gear. There just isn't enough framework to handle grass landings even with larger wheels. I removed the wheel pants as well. On hard surface the gear holds up better. I rebuilt the gear area and haven't had any problems on grass. Glad I bought a Eflite 480 motor, the added support requires it. The wood itself, Asian plywood, is fragile and is easily broken. Horizon recently cranked the price of the plane to $170 and I think is a lot of money for this plane.
My two cent worth.
