I think this is an important question that should be answered. I personally don't know the right answer.

The Tower Trainer is a great airplane. My uncle flies small electric planes and I had him up on a T.Trainer over the summer, and he did very well with it. A properly tuned engine is very reliable, as long as everything in the system is in good shape.

It's cool to see people go from electric to glow; lately it seems to go the other way (like me!)
