Changing brick from Vapor to Ember2
While flying Ember2 outside ,after a rain shower, water got onto the brick and "shorted" a circuit on the rudder servo. Some smoke came out and the servo goes full left ONLY. I have two Vapors and want to replace the "shorted" brick with one from a good Vapor. It is NOT clear how to release the servo rods without bending them beyond use. The "brick" slides into some rails on the mount but, some "goop" holds it in. What is it?? Any help is appreciated!!
