I am looking for suggestions on a better way to lock one of the levers in the RC remote control. This older thread http://www.eurobrick...remote +control had one method, as shown in the first image, but is a bit bulky. I would like to be able to lock the lever position in a two-remote set-up, with one of the center remotes being the lockable one (second image, lime-colored lever). The function will be for lights on/off on a 4x4 with independant front and rear steering. Any thoughts would be appreciated. (Chewing gum and other non-Lego solutions are not preferred).
