I built two of the 4" Red Maxes - one Red with a 38mm mount, and one "Blue Max" with the stock 29mm mount and Stickershock decals. I badly damaged the red one when the chute fouled, so I'd picked up another kit with the idea of replacing it - but ended up repairing in and stuck the unopened new one in the closet.
Sold it on ebay a few months back for $153...
