For those folks who may have an old 5000 kicking around you may wish to avail yourself to this service. A fellow member here on RTF......wjtb23 has been refurbing them. ( Lab Worx <email@example.com)
Not only does he give you a 'better' than new launcher he adapts them to shoot either the max bumpers or the regular 2" knobby bumpers. On the inside everything has been beefed up, in my opinion better than they were new.
The icing on the cake is that with changing the wiring on one relay(2minutes) you can change the 5 shooter into a retiring gun. I believe it is posted on you tube. The wiring change allows the turret to rotate 180 degrees giving you a white stick man on one side and a camo version on the other. It in-retires with a push of the transmitter.
Hard to beat this idea!
