Mechanical Mixers
As most people still use non-computer radio's someone should have a use for these mechanical mixers. Both are simple to make and can be used for flapperons as well as elevons. So if you're into delta's, flying wings or STOL you'll find a use for these.
The first type is easier on servo's as both the servo's are in the usual fixed position, but it may take a bit of experimentation to get the throws you want. You can make the levers from paxolin or fibreglass printed circuit board or similar. Make sure everything is as slop free as you can get it and it'll work well.
The second, sliding tray type works very well but demands you make sure the tray slides easily on its runners otherwise undue stress is placed on the pitch servo, which has a hard time anyway because it has to move the whole roll servo in its tray as well as the elevons or whatever. Also in a crash the weight of the tray and roll servo suddenly shooting forwards will break the pitch servo arm or even strip the servo gears.
