Chris, your conscience is clear and your close friends know you are a stand up guy. I have been following the Florida Club 40 scene recently and looks like they are a great bunch of guys. I have a bunch of PRO 40's some of which I purchased off Ebay used. I need to check all of them not only for displacement but also for enlarged carb venturi and muffler stinger ID. I was at a race last year and they were checking and I had a stinger that had been drilled out, it was an ebay purchase. I was so embarrassed. Fortunately it was at the prerace tech insp and I changed out the muffler. Sorry to hear your year total was lost. I feel that eventually Thunder Tiger will discontinue the PRO 40 and will only offer the 46. TT is the only company continuing to offer and R/C 40. All the other quality manufacturers have gone to the .46. And as electrics continue to expand the Nitro market is shrinking. I see OS has read the tea leaves and have brought out a line of electric motors.
Anyway, I hope to make one of your races next year. It will probably be one of the Gainesville races as it is the closest to me as I am in the Atlanta area.
