That leads me to my question for help T.O.M.
Did you ever end up building that 342 powered 50%'er and was the aditional engine size worth it?

I am about to pull the trigger on either a 275 or a 342 for another of the same airframe and trying to decide if those extra cubes create any major difficulties. Once over 55 lbs, I have to deal with all sorts of paperwork here anyway so if the build is still simple and the performance rocks, I will go for the bigger one, If not worth it, I wil go for the one the plane was designed around.

Wish I could come for the 7.62 "play time" too? One of my other sports was Full bore Target (haven't done it for a while though) I still have my Gilkes Ross - that sport and the Horse Stud seem to have gone hand in hand a lot recently.
