No sound for elevation, traverse. I believe the pico switch is for the tank to "turn off" when you turn the TX off. I've never dealt with them but believe the idea is if the RX loses signal
or power the last functions inputted are used. So if you're full throttle and turn off the TX, tank is rolling at full speed. I now remember your problems with messing around with servo
elevation. I know what your saying on the elevation sound not ending so you can't fire, but the camera hold module stops this issue. If your just using a rate reducer to slow the servo
this doesn't solve it, just slows the servo. You have to hold the servo positon (and your input via TX) to not get the elevation input and block firing. I've used the camera postion controller on
various tanks and my bazooka dude and it holds the position of the servo just like your using a tammy. In other words, push up/down on your stick to move elevation and when you let go and stick
goes back to neutral, barrel holds at moved to positon and no sound from MF.
