PITCH TRIM SYSTEM TENSION 

.....

 While writing Section II of these plans, and building N81QA, we 

built a simple system to vary the tension, or drag, on the pitch trim 

wheel. 

.....

Make a third TS-1 bearing from phenolic. Drill a 3/8" diameter 

hole as shown. Next, saw-cut the bearing through the hole, but do not 

go all the way through and make. two pieces. The lower half of TS-1 

is bonded with resin to the end TS-1 bearing already mounted. Do not 

bond the top half or the system will not function. 

.....

Study the sketch. By turning the screw, the size of the 3/8" 

hole can be varied slightly, changing the tension on the pitch trim 

drum. A knob bonded to the screw would make tension adjustable in 

flight.
