I did my 4*60 much the same way... I cut the canopy back so I could have a widnshield with an open cockpit and use a "Marvin the Martian" for a pilot figure. Powrered by a TT91 four-stroke mounted horizontal with an cap/extra-like cowl from Stan's Fiberglas. Taller and heavier landing gear from TnT since I fly from a rough-ish field.

No picture of it yet, but I'll get one done soon.
