Just thought I'd ask cuz I had saw a guy with a DP Ultimate with a DA in the classifieds but he said/listed he had never flown it....

Man, it'd be a rocket, for sure. My Brison 2.4 (a 40cc engine with far less power than a DA50) was awesome on the DPM for power. It was absolutely a rocket, and as long as the nose was pointed straight up, it was a blast to fly. But everywhere else it was horrible. I ended up pulling the engine out after 5 flights (1 day at the field), and getting rid of the plane and engine seperately. The plane is awesome, it was extremely capable with the OS160, and relatively easy on fuel. If I were to get another DPM, I'd go with the OS again in a second.

lol I was thinking about a DA in a CG Ulti. but I am looking at other weights on engines now... no one says the left stick has to be all the way up.
