What is the model plane electric motor type, an outrunner?
A few years ago, I built this series hybrid motor for an electric bicycle. I think the permanent magnet motor that I chose was the weak point in the system.

If I could find the right type of electric motor I might revive this relic.
Can you give any specifications on the supercaps?
