Sterling Ringmaster C/L Airplane

Sterling Ringmaster control line kit parts - Airplanes and RocketsThe Sterling Ringmaster is truly a classic control line model that allowed many people to learn to fly the AMA stunt pattern.

A while back, I bought a Sterling Ringmaster kit off of eBay with plans to build and fly it. Since that time, I have sold the kit.

Wingspan: 42"

Length: 27¾"

Engine: .19 to .35

If you go to the Brodak website, you will see that the new profile stunt kits are priced at around $60 - $70. This classic typically sells on eBay for between $75 and $125, with no good reason why the price varies so widely.

A couple companies have begun selling laser-cut kits- or at least short kits - of the Ringmaster. I'm not sure which version they are making. Here are a couple sources for a Ringmaster kit.
