IMO this site has been self moderated and well done at that. Look at how many posts involve larger than "1/2A" engines/planes.... not too many huh?
I dont think any change is needed. And I especially dont think anyone asking about, say, a Cox 09 or similar, should be booted out to another forum where the rest of the guys will go "Huh?"
Just my opinion but why change it if it isnt broken?
