One-Design Rubber Event

In 1998 Bill Vanderbeek instituted the popular One-Design Gas event, for ubiquitous small gas designs such as the Starduster, Mini Pearl and Ramrod. Borrowing from Bill’s great idea, the 2016 NATS featured a One-Design rubber model, My Coupe, in honor of Bill Vanderbeek. This super-simple Coupe design was the 1972 Model of the Year, is easily built of balsa, and equally easy to fly.

The rules for NATS One-Design Rubber are short and simple, and are designed to encourage maximum participation by modelers young and old, novice and expert.

The 2022 design is the Bustard P-30, in honor of its designer Jim O’Reilly. There are several versions of the Bustard, including the well known Tubular Bustard, and all are eligible for the One -Design event. Bustard plans (P-991, P-992, P-993, P-995) are available from NFFS Plans Service.

Nominations for future One-Design selections are welcome. Some designs being considered include:

• Perryman P-30s
• Perryman Fludy Coupe
• Oldenkamp HotBox P-30
• Bob White Twin Fin P-30
• Bob White Twin Fin Coupe
• Lidgard Sparky
• Blue Ridge Square Eagle P-30
• Blue Ridge Coupe Neville
• Romak’s Gin-U-Win
Champion P-30
Champion Coupe

The vision for the One-Design event is to pick classic designs that many folks probably already have kits or built models for. Ideally, we’d like to keep it as a 2-minute event, so all the designs may be flown in a combined event.
