Great flying airplane. It's been about 10 (maybe more) years since my last one. I flew mine with 2-stroke engines which are a bit lighter than the 4-stroke; so plan accordingly (maybe move the engine back). I'd probably go with fuselage mounted, fixed landing gear, too - reinforce the fuselage appropriately.
I still have a set of wing/stab/fin&rudder cores as well as the fiberglass top section and cowl for the fuselage. Email me directly if your interested.
