Trigger Wire Loop
Take approximately 60mm of wire typically used in slot cars to connect the guide braids to the motor. This is very flexible multi-core cable ideal for this application.
Solder one end to the point on the main board marked 'T'
loop it gently as shown in the images and solder the other end to the trigger saddle.
Try to get the cable to run along the trigger body as far as possible to reduce metal fatigue on
the soldered end.
This additional loop of wire assists the middle contact strip on the contact board and helps with the brake and maximum trigger positions in particular. It also serves to maintain connection for all the other trigger positions.
