Yeah, you could pull a J easy in a 5.5" bird at Williams Farm, and a K on a 6-8" wide bird. Heck, Bob Strauss (an interesting character and old prefect from years past- not to be confused with the Bob SCHONER that you know) flew some clusters in his Odyessy rockets (big 8-10" sonotube-bodied cluster rockets) that reached the low "L" range. They were huge, heavy rockets. I wouldn't try that, though, and Ralph wouldn't have it. Heh. But I'm going down to Orangeburg for the next two months (this month's an experimental launch...just visiting), but I'm planning on flying some bigger stuff in August...you and your dad should come down. I'm probably not gonna go to Freedom due to college constraints (it'll be busy once that starts) so I'm gonna do my big flying in August if all goes according to plan. You guys should come down, too. Your dad's not L-2 yet, is he? O-Burg'll be a good place to do it...
