This upgrade includes the complete trim wheel assembly and Bourns 10 turn potentiometer which will give a more realistic sensitivity to the elevator trim and 10 complete rotations of the trim wheel. The controller with the base configuration has approximately 4 complete rotations of the trim wheel. This is for those who already have a controller with the base configuration and want to upgrade. Easy to do upgrade, it takes less than 5 minutes to swap the old assembly out and install the new.
** This is for all controllers that have the square trim wheel housing, this will not work with the old round back trim wheel housing design.
Directions on how to swap out the trim assembly.
Unplug the usb cable from your PC or back of the controller, remove the 4 screws on the trim section and remove the 6 screws on the top of the controller (torx t10 screws). Unplug the most forward 3 pin connector from the controller board (closest to the throttle knob) and pull out the entire trim assembly, fish the wire out from under the throttle slider. Push the new trim assembly wire through the hole from the trim assembly into the main case, run it under the throttle slider (most forward section is fine and easiest) and plug the connector back into the controller board, red wire goes to the right, towards the mixture control. Make sure the wire is clear of the sliders and then put the screws back in and all set. You should calibrate the controller again in Windows Control Panel and should be good to go!
