Since coming back into the hobby after twenty years of zip, it's been a long time since I flew 4strokes in competition. Upon returning, I naturally went electric because they didn't exist back in the day and it just seemed great to avoid all that fuel and hardware for nitro. Still, loved the way the YS ran, even used a lot of his 2strokes as well, great products. I've looked closely at the Naruke fuelie installations and it looks like the biggest pain in converting an electric to fuel is the lack of lower cowl hatch and provision for exhaust pipe. Maybe FlightHobby has a "mini conversion kit" available. I could inquire with a friend to see if they've done it and can offer any assistance.
