  Little BIG Winch PAT. PEND.

Get big winch performance in a 16-pound package you can carry in one hand. Coupled with your 12 volt, deep cycle, lawn tractor sized battery (GNB #DCU1-34 or equivalent) the Little Big Winch will launch your open class sailplane dozens of times at a flying session. The Little Big Winch system "A" comes ready to fly with 1400' of line, swivel, parachute, heavy-duty turnaround, securing stakes, foot pedal switch, and high amp battery quick-connectors.

The Little Big Winch is a compact RC sailplane launching winch, built on an anodized, all aluminum frame for light weight. The cool running, powerful motor utilizes rare earth permanent magnets and robust bearings, and is fully capable of launching and zooming 3-4 meter sailplanes.

I designed the Little Big Winch to be used as a personal, practice winch, and really was aiming for maximum convenience with as much launch power as I could build in, still keeping it light and small enough to be carried in one hand. At 16 lbs. this winch is extremely portable, and if you use the suggested riding mower sized deep cycle battery, you can carry that and the turnaround in the other hand. You will find that the Little Big Winch sets up nearly as easily as a hi-start, yet unlike a hi-start, is usable in cold weather and on any size field without modification. One trip to setup truly makes it possible to go winch flying on your lunch hour. Fly when YOU want to with a Little Big Winch.

Manufactured by I.R.F. Machine Works, Inc., Milwaukie, OR.

On-going design updates


The motor that is the heart of the LBW was the result of 2 years of R&D and customer feedback . All complete packages now also include the newly redesigned "Ultimate Turnaround". (Note: the "Ultimate Turnaround" is also available separately)

New Anti-Spooling Brake

This design has been so successful that it is now standard on all new winches

(also available as a retrofit)


More easily removeable Reel

The motor shaft is now threaded, and the reel is retained with a locking nut,

thus making it possible to remove the reel from the winch while it is still loaded with line.
