In my humble opinion, this is the best kit ever produced. You want to talk about fun!!! I powered mine with a saito .56. Definately not underpowered, and that was at an altitude of over 5,000 feet in Denver! The Saito.72 'ought to be rip roarin' fun!!!

I never ran into the ballooning problem- Everything was set at o%; the engine, wings, and elevator. In a knife edge it would pull towards the cockpit, so I added 1% of negative incidence in the top wing. It seemed to correct the problem without changing elevator trim much.

C.G. came out perfect with no other weight needed for balance using the .56.[8D]
This is a great plane!!!!!!
