Fast was so much fun when you had to do everything yourself. There were no definitive paths to being competitive, just the willingness to put in your time and network with those who knew engine work tips and plane design.
Then everything became "Cookie Cutter" with Nelson .36s and Russian Arfs. The models performed like never before but the sport no longer had the magic feel it once had when you could walk the pits and rarely see the exact same set up twice.
Now there are alot of hot .36s going to waste as well as some Fast Combat building materials....might as well use that stuff up in other ways and have fun...!
I have one of those never ending rolls of Seal Lamen too. It's also called Doculam now.

FAI models and Fast rules makes good sense and should appeal to the majority. I also like 80 mph flown with Magnum .15s.
