OK folks dont want to derail the discussion but intend to contribute to it. Ive been playing with, and racing, B sport and mod tunnels for many years now, even gotten to the podium more than once. As most you guys in this conversation know I am not a tunnel designer or builder (did build my Villian S1 from Mikes Kit, still love that boat!) but rather depend on you that do, including Tommy, Grim Racer, Carl, and Kris. And as you all know I do spend the time testing testing testing the whole combination to get a particular hull/motor to its best performance, at least within my capabilities. I think there are many who just wont take the time to know their boat and optimize it, just want to buy their way to the podium, and most fail with that mind set while missing out on a lot of fun.
I am eternally grateful to all you (and many others) who have helped me along the way, and have in a BIG WAY allowed me to ENJOY this crazy hobby not just thrash around in disappointment.
Enough said, time for group hug LOL
