Frequently Asked Questions
How do I clean and sanitize a McFarlane Push-Pull Control?
We make the following cleaning and sanitizing recommendations to be completed between flights:
Recommended Cleaning Process
1. Put on clean disposable gloves prior to cleaning and disinfection.
2. Pull controls back to the fully retracted position to expose the full length of the control shafts.
3. Apply isopropyl alcohol to a clean microfiber towel. Do not spray any solution directly on the controls or any other surfaces or components in the aircraft.
!!! WARNING: DO NOT USE BLEACH WIPES ON ANY MCFARLANE CONTROL !!!
4. Gently and thoroughly wipe down every control knob surface and control shaft.
5. Let cleaning solution dry on these surfaces (contact time).
6. Use a clean and dry microfiber cloth to wipe away any solution residue left on knob and control shaft surface.
7. Remove all gloves, towels, and cleaning supplies from the work area in the aircraft.

How do I trim my engine control to length?
Please reference the Installation Instructions included with your new control.
I purchased a laser engraved knob and the thickness of the marking is very shallow. What kind of wear resistance can I expect?
The laser marking does not harm the hard durable anodize coating on the aluminum knob. The CO2 laser process only bleaches the color from the anodizing leaving a silver white color that contrasts with the surrounding dyed anodize. The durability of the laser marked area is not affected by the laser. Our tests have shown that the laser process actually improves the corrosion resistance of the anodize layer. The CO2 laser engraves aluminum knobs by vaporizing the surface leaving a deep durable groove. This groove is then filled with a special paint for contrast. The result is a durable long lasting mark.
What is the minimum bend radius for my engine control?
McFarlane's Storage and Packaging Specification requires a specific packaging minimum radius based on the length of the control, type of wire used, and the configuration of the control end(s). Please contact us to determine the exact requirements for your specific control.
