Put the new Rossi in one of the Phoenix' here. Started first flip, right out of the box. APC 12X7. I have never used a tach. For a new powerplant, I am impressed. I have heard story's about the carb, but it comes down fine, great transition from idle. For a new ABC, looks good, sounds great. Using a Mac's muffler with adapter's, may have to use the single adapter and another Mac. Muffler hanging a little low, may go to a 2.25" wheel on front. I was told, 2 gallons to break it in. That will be in the air.
Any suggestion's on this Rossi, I would appreciate it, but all looks fine. Using 15% Omega. I had to try this out, vs. the OS61FX's in the other planes. I don't like the rear NVA in the tight opening.
