The Picco arrived along with the header from SG Rossi USA. It's a perfect fit.

I will try to run it this weekend.

It weighs about the same as an SF .61. So, now, I have a choice to make for my UFO. I can set up the SF with a pipe to turn a 12x8 at around 12,000, or set up the Picco to turn higher rpms with an 11x7.5. I'm not sure what rpm to expect out of the Picco. Does anyone have a ballpark target figure? These two engine setups seem like they would fly the plane quite differently, but maybe not.
