I raced Gold Class SAM & SWRA for years, then took a ten year break from RC. I came back last year after I found out I had blood/bone cancer, RC takes my mind off the Cancer & gives me something to do during the day. I returned to racing more for the fellowship more than anything else - and boy, had things changed in ten years! Yes, I am the proud owner of two brand new YS 115's (A really good friend needed one for a day so I bought him one to use for one race). I am, in my heart, a two stroke guy! If I can pipe it, I'll fly it. Like Planebender said, It's what you can afford/ or what your priorities are...... I'm not rich on disability by any means, but with my disability I spend every cent on RC.....sold my motorcycles to do it - even when it hurts too bad to walk or stand, I'm working on airplanes. It really makes me not happy when I see the guy wanting to use a 120AX, but exclude DF or F.I.R.E engines......Why? The two strokes need all the help they can get. Like I said, I have two 115's - that's what is winning.....If Rosssi 91's were winning, everybody would have one - there're not. I'm building two four stroke powered Gold planes, a four stroke Silver & practice plane, and two 2-stroke planes - testing will see if they make Gold. That's five planes, hopefully one will place. If not, I'll find a pilot to fly them for me that will....... just my .02 cents!
