Installed a control lock, to keep the flight surfaces from moving when tied down in the wind. This was really easy ot put in, since I removed the panel to label things anyway. I had previously made a lock that goes around the rudder to keep it from moving in the wind, which is important, because it's linked to the tailwheel. I've had 45mph winds come through here, and it didn't move the elevators or ailerons without the lock, but I it will surely be more important to have on in stronger winds.
