The Build – Part 10
The throttle linkage can be a bit tricky on nitro powered vehicles. Once set, however, you should not have to adjust it again. The RC8.2 also features an adjustable brake bias. When set correctly, this can be a helpful tuning aid.

Build Notes:
Take your time with the linkage. This controls the throttle position and must be as precise as possible.

Insert the screws through the appropriate holes in the throttle servo horn. Note the location of the screws in the horn and the parts that will be attached to them.

The actual throttle rods. Note the difference in lengths. The one on the left is for the throttle, the two on the right are for the front and rear brakes.

Insert the long brake rods into the thumbscrews as shown and lock into place with the setscrews. A dab of loctite is a good idea here. Now screw the brakes rods into the brake bias block as shown.

Build the throttle linkage as shown…

…and screw into the throttle pivot block. Secure with the third thumbscrew and setscrew. Don’t forget the loctite on the setscrew.

Make sure the throttle servo is centered and attach the throttle horn to the throttle servo.

Slide the brake levers into the brake cams and secure with the setscrew. A dab of loctite on the setscrew is recommended.

Slide the brake rods through the brake levers and attach the radio tray to the RC8.2 chassis using the six 3x12mm screws. Loosen the setscrew and adjust the brake levers until the brake rods are parallel with each other.
