Welcome to the Sullivan Products Website!

Manufacturer of High Quality Radio Control Products and Model Accessories for Over 50 Years.

Sullivan Products was founded over 50 years ago and have been in our 40,000 sq ft plant in Baltimore, Maryland for over 40 years. It began as a small manufacturer of control line products for the consumer model aircraft market. These high quality products were a success, and over the ensuing years Sullivan created products for the growing radio control segment. In 1982, Sullivan merged with The Perfect Parts Company and served broader range of markets with a line laboratory glassware, science equipment and model railroad accessories. This gave Sullivan access to even more engineering and equipment resources. In the late 1990s Sullivan entered the expanding Unmanned Vehicle market. Many of the UV products were a direct result of the experience Sullivan had in vehicle electronics/power systems, control hardware, and fuel systems. We currently maintain a variety of plastics processing equipment, metal working machinery as well as electronic assembly and testing equipment. This allows us to design and manufacture products on a subcontract basis. In addition to the military market, we also deliver turnkey products for the consumer and commercial markets.

Thanks to the vigilant observations and information passed on by a few modelers over the last month we have come to the conclusion that a relatively small number of our SkyWriter Smoke Pumps can freeze up and quit pumping due to a manufacturing issue. We changed the flux we use when soldering the motor wires a few months ago and unknown to us in some cases it is caustic to metal causing surface rusting of the rear shaft. In most cases the small surface rust that can form is not enough to stop the motor and worn off with use. Unfortunately, in some instances it drags down the motor and keeps it from running.

Although this has occurred in a small percentage of units, in an effort to always provide high quality products for our modelers, we decided to pull all SkyWriters in house and from our distributors. They will be replaced with new motors and motor wires soldered with a new benign flux.

If you have purchased a SkyWriter in 2017, it has stopped pumping and you have not already contacted us please call or e-mail us so we can ship you a new SkyWriter.

If you purchased a SkyWriter in 2017 and it is working fine, you will probably have no problem with it. If you choose to keep it and it decides to lock up later, we will still warranty it for you. We have stood behind our products for 59 years and continue to do so today.

New Product Information


NEW - Sullivan ProFlex Universal Fuel Tubing
The ProFlex line of universal tubing is a proprietary Fluoroelastomer (FKM) tubing that will Never
harden. ProFlex has been designed and tested to be impervious to gas, glow, diesel, and smoke oil. The thin walls allow maximum flexibility without kinking. Three lengths, 6" tank replumb kits, 2' length, and 12' length, available in two different sizes, Standard and Large. For more information click Here

Now available at your favorite Sullivan retailer.

ProFlex Standard (S210, S211 & S212) has a 3/32" ID which is exactly the same ID as the silicone fuel line that comes with every tank. It is designed to fit 1/8" Brass tubing as well as standard size fuel fittings.

ProFlex Large (S214, S215 and S216) has a 5/32" ID which is designed to fit 3/16" brass tubing as well as large size fuel fittings. In order to use the large size ProFLex in a tank you must replace the brass tubes and klunk to 3/16".

We designed our new ProFlex fuel line with a US chemist and rubber compounder to develop a proprietary formula of FKM (Fluoroelastomer) that is chemically resistant to gasoline and ethanol which is what causes Tygon tubing to harden and deteriorate. With the help of an experienced US extruder, ProFlex has a thinner wall than commonly found on the Tygon that is used today. The thinner wall allows for more flexibility, lighter weight and easier attachment to tubing and fittings used in the RC industry.

NEW - #S751 High Capacity Fuel Filler Valve
Filling fuel tanks in RC models has never been easier until now! This new aluminum alloy fuel filler valve is perfect for large or giant scale aircraft. The fuel filler valve comes with stainless steel twist ties clamp wires and mounting plates with screws.

    • Fill or De-Fuel Tanks Safely
      - Without disconnecting any fuel lines

    • Pull To Open - Push To Close
      - Prevents engine flooding while refueling

    • Safe for All Types of Fuels
      - Gasoline, Glow Fuel, or Smoke Oil

    • Easy Mounting and Installation
      - Mounts flush against model’s fuselage

    • Works with 5/32” Fuel Tubing
      - No extra connections or tools needed

Connect the new fuel supply tube to the fill nipple in the center of the red aluminum plunger. Gently pull the plunger outward until it stops. Once the filler valve is fully opened, you can now safely and easily begin to fuel or de-fuel the tank. The fuel line to the carburetor is automatically shut off from the new fuel source when the plunger is pulled out. This prevents the engine from flooding while refueling. When the fuel tank is full, simply remove the filling tube from the fill nipple and push the red plunger inward until it is closes inside the valve body. With the top of the plunger now flush with the fuselage, your model is now ready for action. It's that easy!
