RC Plane Lights and Smoke Systems Explained

Wiring an ESC to run a motor is one job. Adding a string of LEDs or a smoke pump to the same airframe, without overloading the receiver's power, is a different one, and it is the part most "RC plane lights" roundups skip. They show a row of red and green LEDs and move on.

Lighting an RC plane really covers three jobs. The first is making the model visible and readable in fading light, which is navigation and anti-collision lighting. The second is scale realism: landing lights, strobes and wig-wag effects on a warbird or giant-scale build. The third is a separate discipline altogether, onboard smoke for gas and glow aerobatics, which involves oil, tubing and engine throttle more than electronics.

This is a researched guide. The specifications come from the makers' own manuals and product pages (E-flite, MyTrickRC, Sullivan, PowerBox-Systems, Robart), AMA safety documents and a Model Airplane News installation article, not from our own flying. Stock was read in October 2026. The one decision that applies to all three jobs is power: how you supply the load without starving the receiver, covered in the ESC guide and the wiring guide.

Night Flying Rules First

If any of this is for flying after dark, start with the rules. The AMA's night training document says that for night flying, AMA requires aircraft to carry anti-collision lighting that can be seen from 3 statute miles away unless it poses a hazard or distraction to the operator. Other lighting must be used so that you can determine attitude and direction of flight. Hand-held illumination by itself is inadequate. The same document says night flight requires completing AMA video training (through modelaircraft.org/night-operations), through introductory pilots, or by a club's safety officer, and defines night as the time between the end of evening civil twilight and the beginning of morning civil twilight.

It adds a practical caution: flickering lights and anti-collision lights can interfere with brain function, and pilots may turn the anti-collision lights off if they create such a hazard. It also advises practicing basic maneuvers at night, including straight-and-level flight, climbs and descents, level turns, climbing and descending turns, and steep turns. Your club may add its own rules, and federal rules apply too, so check the FAA's current requirements before flying after sunset. This guide does not summarize them.

Quick Reference

How Light Kits Are Powered

Most kits plug into a spare receiver channel and use the receiver's own power rail. That works if the load is small and the rail has headroom, which is why the numbers matter.

The E-flite Universal Light Kit controller is a good example. Its input voltage is 3 to 5.5 V, and its manual warns not to exceed 5.5 V because that will damage the controller. It controls up to 16 E-flite Universal Light Kit LEDs, switched on and off by a spare channel assigned to a transmitter switch, with the switch point at roughly mid-stick (on above 1.5 ms, off below). Its average current at 5.5 V is 60 mA for 6 LEDs, 120 mA for 12 LEDs and 160 mA for 16 LEDs, which works out to about 10 mA per LED.

That is small next to a flight battery, so LED drain alone will not shorten a flight. The real risk is the receiver rail. Spektrum's AR620 guide calls inadequate receiver power the number one cause of in-flight failures and says to confirm the voltage stays above 4.8 V with servos heavily loaded. Add lights to that budget with the servo figures from the ESC guide: E-flite's ESC allows 7 analog or 6 digital standard-size servos on its BEC, before lights.

MyTrickRC's UF-7C controller adds two cautions in its own notes. The pigtail output passes receiver power straight through, so the voltage there equals the receiver voltage, and the maker warns not to draw more power off the receiver than it is rated for. Each output can power many LEDs, but the more you add to one output the dimmer all of them become, and MyTrickRC recommends not exceeding 4 LEDs per output. The controller's rating is 4.5 to 12 VDC at up to 2 A, though MyTrickRC says it is better for the controller not to exceed 9 VDC.

Navigation, Strobe and Landing Light Kits

E-flite Universal Light Kit

E-flite Universal Light Kit on Amazon

This is a modular system: a controller (EFLA600) plus LED pairs bought separately, in red, clear, blue, green, yellow and orange solid and flashing versions, with extensions and Y-harnesses for placement. You choose the layout, so a red and green wingtip pair, white strobes and a flashing red beacon are all possible. Many LED pairs were in stock in October 2026, including red, clear and green solid and red, clear, blue and green flashing. The controller was on backorder, so check supply before planning a build around it. Because switching is by one receiver channel, it turns the lights on and off but does not offer scale patterns.

MyTrickRC Large Airplane Light Kit

MyTrickRC Large Airplane Light Kit on Amazon

MyTrickRC built this kit with Southern California flyers for larger aircraft. It fits wingspans up to 90 inches, with 8 inch and 12 inch extenders available beyond that. Its key feature is quick-disconnects, which make it simple to separate the wing from the fuselage, and the kit is plug and play with no soldering. Remotely switched landing lights come standard (leave the servo lead unconnected if you do not want remote switching).

The UF-7C carries aircraft modes. Warbird mode offers wig-wag landing lights and gun LEDs, and Fighter Jet mode adds switchable landing lights, gun LEDs and an afterburner effect that activates at full throttle only. MyTrickRC also describes flat downward-facing "Attack" headlights that can be bonded under the wing for better ground visibility on approach, connected through a light bar adapter cable or regulator. The kit was available from the maker in October 2026. This is the kit to look at for a flying warbird whose wings come off for transport; see the warbird guide, the best RC warbirds and giant-scale guide for the airplanes, and the landing gear guide for the other scale hardware that usually goes in the same build.

MyTrickRC Small Airplane Light Kit

MyTrickRC's first airplane kit is designed for wingspans up to 40 inches. It carries a UF-7 family controller with scale blink patterns, and the kit has 20 inch leads: a green and a red nav LED, two white landing LEDs, two white wing strobes and two red fuselage strobes. It runs from receiver power with a 9V battery adapter included. The maker says dusk is an ideal time to fly with these lights, since the body of the plane still shows against the sky. Both MyTrickRC kits were available when checked.

Budget Kits Without Published Specs

Several budget LED kits circulate on marketplaces with claims about current draw, lead length and low-voltage alerts. No maker pages for those kits could be found, so their specifications are not repeated here. If you buy an unbranded kit, find its current draw and input voltage range on the listing and compare it with your receiver's rail before connecting.

Smoke Systems

A smoke system is mostly plumbing. Model Airplane News lists the parts as a smoke pump, fuel line, a smoke oil tank, fittings and a smoke muffler. The pump injects oil into the engine's hot exhaust, where it vaporizes into a visible trail. That is why it is a topic for gas, glow and turbine models and not for standard electric power. See the turbine guide for that world.

Sullivan Sky Writer

Sullivan Sky Writer Smoke Pump on Amazon

Sullivan describes an internal microprocessor with an electronically controlled smoke rate, adjustable in flight with a programmable radio or slaved to the throttle servo. It has an ultrasonically welded direct-drive pump head, weighs less than 4 ounces and runs from any 4.8 to 12 V battery (6 V or more recommended). The kit includes tubing, fittings, a double screen filter and a check valve, and you supply the smoke tank and muffler. It was in stock at Horizon. Sullivan's electric field pump, a reversible gear pump rated at 33 ounces per minute at 12 VDC for filling tanks, was also in stock.

PowerBox Smokepump

PowerBox Smokepump on Amazon

PowerBox-Systems makes a metal-geared smoke pump with a flow rate variable from 0 to 100 percent and no separate cut-off valve. The standard version moves up to about 750 ml per minute and the Jet version about 950 ml per minute. It operates from 4.0 to 9.0 V and draws about 1.5 A at full flow and 10 microamps in standby, and it can run straight from the receiver supply or from a separate battery, going into standby if the receiver loses signal. Its manual recommends Tygon fuel tubing on the intake, heat-resistant tubing to the silencer and, notably, not using a felt pick-up or other intake filter because viscous smoke oil can cause cavitation. Sullivan's kit ships with a double screen filter, so makers differ; follow the manual for the pump you buy.

Power, Throttle and Plumbing

Model Airplane News says smoke pumps can draw as much as 1 amp and average about 17 mAh per minute, and recommends a larger-than-normal radio battery pack if you plan a lot of smoke-on time. The LiPo guide covers pack sizing. The article's installation tips are practical:

• Secure the smoke tank directly above the center of gravity so trim does not change as it empties.
• Keep lines short, mount the pump close to the tank, isolate it from engine vibration with rubber washers or foam, and clamp every connection.
• Use check valves at the mufflers with high-temperature neoprene tubing.
• Program the pump with a throttle-to-pump mix so the switch gives fully on and fully off, with the pump held off at low throttle and ramping to maximum at full throttle. The author's mix keeps it off until around 30 to 35 percent throttle (the article gives both numbers), because too much oil in the muffler at low throttle can stall the engine.
• Start the engine with the smoke switch off.

Smoke Oil

Use a smoke oil made for the job. Robart's Liquid Sky is sold with a foam-safe formula and is described by Horizon as producing a superior plume with extended smoke endurance for turbine or piston engines with on-board smoke systems. It was in stock as a case of four 1-gallon containers. The PowerModel jet smoke oil from Deluxe Materials was also in stock and is described as proven with jets and gasoline engines. PowerBox lists its pump for "Blue Max" or 3W smoke oil, and Sullivan's own SkySmoke gallon is discontinued at Horizon. Whichever oil you pick, confirm with the pump maker that it is approved for the pump, and do not assume other liquids are safe on foam or covering. Plan for some mess, since oil can find its way out of a compartment; sealing the area and wrapping the receiver and battery before a first smoke flight is sensible, though the sources read do not address cleanup.

Electric evaporator smokers exist for electric aircraft. No maker documentation was found for them in this research, so this guide does not give figures or recommend a model.

Common Mistakes

• Loading the receiver rail. Count servos, lights and any pump together, then test voltage under load.
• Exceeding a controller's input range. E-flite's controller tops out at 5.5 V; MyTrickRC prefers 9 VDC or less.
• Too many LEDs on one output. MyTrickRC says they all dim.
• Skipping the throttle mix on smoke. Oil at idle can stall the engine.
• Using the wrong oil or filter. Follow the pump maker's manual.
• Flying at night without training. The AMA requires it.
