simchair4_software\peripherals - choose the preferred variant of the lever - software

1. Assemble collective base up to the point shown on the pic below and install your preferred throttle frame p1 on it (in this guide I am using a 206-style lever throttle frame p1)

2. Install a throttle pot, the mode switch, and pull the pot cable and a 5-wire (!) cable through the lever.

3. Turn the throttle pot fully left (full open collective as in Bell-206) and the slightly right to clear mechanical deadzone. Put the throttle grip on. Route the 5-wire cable through the cable channel in the the integrated head piece.

3. Prepare an MTS-123 switch, a 6x6x17mm tact button and a PBS-10-B2 button. Solder a ground wire from a 5-wire cable to them as shown on the picture below. Choose the wire at one of the ends of the cable that has a darker color.

4. Solder other wires of a 5-wire cable. The ground wire is wire #1 in the ribbon:

1 → 6x6x17 mm tact button 2 → PBS-10B2 3 → MTS-123 switch right pin 4 → MTS-123 switch left pin

5. Put buttons and the switch to their sockets in thr frame p2
