I have the Spit and FW190. The Spit has a 25cc Brillelli gas engine and the FW190 has a Saito150. They both fly well and seem to hold up to extreem misuse. I don't think they are for the first or second time builder since they do need mucho TLC to prepare them for a solid carefree flight. I used SpringAir retract units in both with Robarts struts on the Spit and custom built 8" Robinaires on the FW190.
tIANci said it very well. (quote below)
CMP planes are fine ... they are all ok ... no need to really worry, they are slightly over the ideal weight only and they fly well.
