I put the 55/4* in the air this am. 11x5 APC, 12800 ready to fly. Really changed how it flies. Vertical forever!! Fast! Flew it the same way I have been. The manuevors just took a lot more sky. For those that say it is too much, can you ever have enough of a good thing? It certainly doesn't need more. This is just a break in plane for me. The engine will be going on a profile edge. The 4* will be getting the other Saito 45 for fine tuning.

My other planes get my heart pumping, a mellow 4* is fun without needing total concentration.
