Frequently Asked Questions:
Which FrSky transmitters are these switch caps compatible with?

What is the difference between the long and short switch cap options?
Long caps provide more finger clearance and are preferred by pilots who need tactile control with gloves or who want easier reach to momentary switches during flight. Short caps sit flush to the switch body and are preferred by pilots who want to minimize accidental activation of flight mode or arming switches. Choose based on your flying style and switch assignments — most pilots use long caps for critical mode switches and short caps for less-frequently used functions.
How do I install the metal switch caps?
The switch caps thread directly onto the existing toggle switch stems on your transmitter — no tools required. Simply unscrew the stock plastic caps counterclockwise and thread the CNC aluminum caps on clockwise until snug. Do not overtighten. The installation takes under a minute per switch and does not affect transmitter function or warranty.
Do the metal switch caps affect switch function or transmitter performance?
No. The caps are purely cosmetic and ergonomic upgrades that attach to the existing toggle switch stems. They add a small amount of weight per cap but do not affect electrical function, switch travel, detent feel, or any transmitter settings. The CNC aluminum construction adds durability over the stock plastic caps.
Can I use these with the FrSky CNC Metal Tray?
Yes. The metal switch caps are fully compatible with the FrSky CNC Metal Tray when used on a compatible transmitter. Many pilots install both together as a complete upgrade package.
