Frequently Asked Questions
Why is my new engine control too long/short?
There are several things that could be different such as engine/aircraft modifications, rigging/clocking of control arm or adjustment of rod end will be needed, placement of clamps or brackets may be different, or a previous installation change such as routing from original.
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.
How do I trim my engine control to length?
Please reference the Installation Instructions included with your new control.
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. Please contact McFarlane Sales directly at 866-920-2741 or 785-594-2741 or sales@mcfarlaneaviation.com if you have any additional questions regarding the disinfection of our controls.
