Thank you for a very good article on the H9 Sopwith Camel. The video at the end is awesome! I also love the sound of the gas engine.

It's incredible to see the performance difference between your gas engine and my small .72 4-stroke on the same plane! That motor must just be crazy to fly!!! My Camel flies comfortably at 1/2 throttle with the Saito .72.
