How to Mount Servos and Wire RC LEDs and Switches
Mount the servo in a rigid bracket, then wire lights and switches to spare receiver channels. A CNC alloy mount holds a standard servo firm, while an acrylic bracket holds a 9g SG90 in a robot or smart car. LED sets run on 3mm and 5mm bulbs. The CNC servo mount costs $9.21 and fits S3003 and MG995 class servos.
Quick facts

| CNC servo mount | $9.21, fits S3003 and MG995 class servos |
| SG90 mount bracket | $12.87, acrylic 10-pack with hardware |
| LED switch module | $7.37, 3 channels, 4 modes |
| LED headlights | $5.55, 3mm and 5mm bulbs |
| Drone strobe light | $2.99, 7 colors, USB-C rechargeable |
| Switch caps | $7.18, fits Futaba, RadioLink, FrSky, FlySky |
Which mount fits your servo size?
A standard servo needs a rigid metal mount. The CNC alloy U-bracket in this guide costs $9.21 and fits S3003 and MG995 class servos.
A 9g micro servo needs a small acrylic bracket. The SG90 bracket 10-pack costs $12.87 and ships with screws, nuts, and washers.
Both mounts ship without a servo. Check the mount listing for the servo class before you order.
How do you wire RC LED lights?
Wire the lights through a switch module on a spare receiver channel. The 3 channel module in this guide costs $7.37 and gives on, off, breathing, and flashing modes.
The RC car LED set costs $5.55 and uses 3mm and 5mm bulbs in red, white, and blue. Fit the bulbs in the body shell and route the wires clear of moving parts.
Power the lights from the receiver or a small BEC. A 5V feed suits the LED sets in this guide.
What does a 7-color strobe add to a drone?
A strobe makes a drone visible at dusk and at range. The $2.99 strobe in this guide gives 7 colors and turn signal modes.
It recharges over USB-C and mounts with tape or ring belts. No wiring into the flight controller is needed.
Check local rules before night flying. A strobe helps visibility but does not replace a legal night flight setup.
How do you protect transmitter switches?
Rubber caps grip the switch and stop slips in cold or wet hands. The $7.18 caps fit Futaba, RadioLink, FrSky, and FlySky 3 gear switches.
A 5-pack of sheaths costs $4.74 and fits FrSky X9D and QX7, FlySky, and Spektrum switches. Pick the color that matches your radio.
Fit the cap over the switch lever and press it home. A cap that slides off needs the next size down.
How do you lay out lights, mounts, and switches in a build?
Plan the channel map before you wire anything. The LED module needs one channel, and each servo needs one channel.
Mount the servos first, then route the light wires. Wires routed last snag on mounts and arms.
Test every channel on the bench with the body off. A light that stays on with the switch off has a wiring fault.
