2revo1maxx, if the guy is using a 3 channel radio, the 3rd channel can be set to put that channel is in an "on" or "off" mode so that the servo doesn't burn up.
I guess it depends on the radio. If it's a trx am radio he'll need to have the linkage spring loaded or else adjusted perfectly. Otherwise it either won't engage the lock fully... or else it WILL engage the lock fully but the servo will be trying to go a little farther to it's end point. If he has a nice radio he can just set the end points and hope they stay put. I would still go with the spring no matter what. It's the same exact concept as the reverse linkage on a revo or maxx.
