Most, if not all the ones I've seen are 'home made' usually out of a few peices of copper pipe, with the appropriate fittings (elbows, T fittings, etc..) All can be found at teh local 'home center'
Make a 'U' out of 2 elbows, 4 peices of appropriate lenght pipe, and one 'T' fitting. Make teh U wide enough for your fuse, and tall enough to hold your plane. Put a 'T' fitting inthe midlle of teh bottom of the U, at slightly more than 90¦. Connect a longer length of pipe to the T fitting on the U. Make a hook ont he end of that out of 90¦ elbows. And Solder the whole mess together.
Add some 'pipe insulation' to the uppers of teh U for plane protection.
Ask a plumber, he'll probably get a kick out of the job!
Make a few, and sell them to club-mates, and make sure you charge enough to cover your initial costs!
