Seems like there's a fine line between underpowered and overpowered. I've read that the 1/4 scale type T-Crafts and Cubs fly underpowered with a 23 - 26cc engine. What about that new Saito 4c gas (FA36)? That wouldn't have as much power as a 36cc 2c gas, right? That thing is also hefty at 61 ounces.

Marcol - the Cub with the 26 on it, what in your opinion does flying it no problem at all mean? The reason I ask is power is very subjective it seems. I don't want hover power, but do want loop from level flight power with the ability for strong uplines (not unlimited vertical).

Thanks
