I went over the top a bit, with the wheels. I really like the look of the Trexlers and think the compliment the look of the Bees. So what I did was glue two 4" wheels together and spun the corners off. The Dave Brown wheels are a little narrow, with the two glued together they get fat like the Trexler wheels. Anyhow, I flew with them last summer for the first time, and it's turned out to be one of the best "Mods" I've done for my Lazy Bee so far.
