I feel sort of like an outsider, but I'm really enjoying reading these posts. R/C was deemed way to expensive by my dad when I was a teen in the '70s. But he did buy me a brand new Yami YZ 80, so go figure. I'm basically building what appeals to me. If it's not allowed in SPA or noncompetitive in todays style that's fine. If i decide to compete then I don't see any problem in building something suited to the rules.
