That's the KMP Skymaster. Got a Magnum 160 twin up front, and a Saito 130 twin in back. When I bought it, (used) it had a Saito 100 up front with a Saito 82 in back, and several POUNDS of lead weight up front to make it balance. I figured that if it needed that much weight up front, it might as well be engine weight It flies great, and I doubt that I'll have to worry much about an engine out
