Electric Pattern

[jim ivey]

All
No one has said anything about the longivity of the motors. The bearings 
have to get really hot. The gears have to take a terrible beating. This may 
not only be a battery issue. How long will the motors last. Are they like 
the race car motors. Do you have 3 or 4 and use the best ones?
More food for thought. I believe this start for electrics Pattern planes is 
the tip of the ice berg.
