I think to get an F-16 class going in the U.S. (it certainly is not going yet), it would be nice to come up with a list of all the existing classes that are potentially compliant with F-16 rules and invite them to Open F-16 Events.
This is not totally true. This has been discussed previously as well, and has proven that the F16 class in the US is growing strong.
I am a total newb to the F16 class, and all classes at that. But I am a future Blade F16 owner. There is plenty of F16's around the US and plenty of action for us as well. The F16's are invited to the GPYC A cat nationals, thats something HUGE for the class, I also pretty sure they were invited last year as well.
The Blade F16 is being built locallly by Vector Works Marine. They tested the prototype at Tradewinds. Did you miss it by any chance? Jennifer Lindsay won on a Taipan 4.9 which is F16 compliant. Now she will go to California and compete for the Walter Cup in a Tiger F18.

Those are a few that I can mention off the top of my head, I am sure there is a lot more to talk about this. But saying that the F16 class has nothing going on in US is pretty vague and is a total blanket statement that has been proven wrong.
