A few years back I was all enthusiastic about converting one of these, until I found out what size, weight and power I will end up having. It is still much cheaper route than buying a Fuji 4stroke gasser, though. And unlike the Fuji 4strokes, you can actually fly these weedie 4strokes upside down.
Thanks guys. Sure it beats the price of Fuji. However after reading through this forum I see it doesn't perform any better than cheap 25cc 2-stroke (I was hoping for more torque swinging the bigger prop). Nope. I guess, the only benefit is the sound, not much worth the trouble and money.
