I personally think that the Hacker motor/gearbox will last a lot more flights then any YS or 2-stroke. No expensive engine rebuilds. The batteries I believe will go 500-600 cycles, but I think you will really need 3 packs to keep flying all day. So that's 1500-1800 flights worth of batteries. I believe they will go bad from age before I put 1800 flights on them!

The real reason though that I want to go electric is just the pure ease of it. No messy oil all over the model, no dangerous starting, and the big one, no pounding vibration. I was just tired of the constant maintenance, primarily on servo pots, that I had to do with glow models. I'm maybe a bit more picky then most about servo performance, but I can see performance degradation in aileron servos in 30 flights on a glow pattern model. The electric should do much, much better. Also, no pipe length issues, no mixture setting, no idle problems, no burnt out glow plugs, etc.

But it does have to perform. I'll have a pretty good idea in a few days.
