Chapter 17 - Pitch and Roll Trim, Landing Brake, and Center Console



The Plan

In this chapter we will install the pitch and roll trim, the landing brake actuator, and the center console. The pitch trim control is mounted on the wheel well, and the handle extends into the cockpit thru the knee hole. The roll trim is mounted on the instrument panel just in front of the throttle quadrant. Both handles are easily accessible from either seat. You will build the landing brake accuator behind the front seatback.

The roll trim adds pressure to the ailerons, to keep the plane flying level wingtip to wingtip. This is a very simple system, a lever to pull on some springs via cables, which adds the pressure. Buy these levers from the Cozy Girrls and save the hastles of trying to make them.

The trim mechanism is completed. Most of it will be covered bt the throttle and cover. It should be easily operated with your had on the throttle.

The Pitch trim is even simpler. The lever pulls the springs directly, applying pressure to the elevator control arm. Here you can see that I still have work to do on the parts I made to get them suitable for aviation use. I will be sanding out the scratches and annodizing them before I do the final install.

The Pitch trim is placed on the left side in my plane. I should be able to operate it with my thumb, while my hand is on the throttle. I get full range of elevator motion using just the trim;-).
