No, I don't know them. I was hoping they would come into Erie, just north of Denver. Ray Middleton and QG Aviation are about 20 miles from there and I was 8 miles away at a race track. But they didn't; follow the schedule the posted for some reason. perhaps they got a $$$ offer or to avoid weather. They went south. QG is the shop that just won Reserve Grand Champion at Osh with Eddie Kurdzel"s Fairy Firefly.
