does anyone have any expericene with this motor? appreciate comments

It will have more power than the same engine on gas and burn at least twice as much fuel.....It will start just like a small glow motor.........Glow plugs last a long time......

And since it's a side port engine it'll run backwards as well as it does forwards. I recall at a past TOC, that someone's glow engine was idled down and it kicked and started running backwards. When he throttled up the plane tried to fly in reverse.......for a very short while.

Correct..Chip Hyde used to do that with his plane and taxi it backwards into the parking spot....
