I built one with a Saito.91, it was decent, with alot of torque. Another friend of mine built one with another Saito.91 w/straight pipe, and runs %30nitro, that is one fast Dago. I built mine and installed a very fresh ASP.75, and it was all but a red streak. Extremely fast. Propped short with an 11x9 which still kept it to manufacturer specs, instant acceleration...I sold it about a year ago....I miss it when I read about them.

They are not the lightest of the stangs, but I'd say they are the most streamlined and tightest of airframes. In a word.. awesome.
