REFLECTOR: evlvator trim

[Andrew Ellzey]

Lou,

I'm not flying yet, but I have added a fast/slow switch in my wiring diagram for this very reason. The plan is that I will switch it to fast mode for takeoff and landing and slow speed for level flight small trim changes as needed during level flight. The two 10K resistors will reduce the voltage to the trim motors to 6VDC for slow speed operation and 12VDC for normal or fast speed operation. Again I am not flying and may have to increase or reduce to resistance to find the actual trim speed that works best.

My switch will be on the Yoke yours can be anywhere you like. I haven't researched how many amps our trim motors pull yet, but 2 ea. 1/2 to 1 amp 10K resistors should handle the load just fine.

See attached sheet.

Andy Ellzey

I find my elevator trim to be too sensitive. The slightest touch of the trim switch takes me up too much or down too much. Is there any way to make it less sensitive? Don't know if a rheostat would be the answer.
