There is a review here on RCU on page 5 in the magazine done by Minnflyer. I got a chance to fly that paticular plane. It handled very nicely. With the Magnum 52 on it it had more than enough power to hover at just a tick over 1/2 stick. The amazing thing that sticks out in my mind about that engine is that it was the quietest thing I had ever heard. And it ran great. You might want to ask Minnflyer how the engine is running now two years later. I know that the plane didn't make too much past the review, as the elevator servo lead came unplugged during it's last flight.
