our products - SUPER Y - P-30 Competition and Rubber Power Sport Model


P-30 Competition and Rubber Power Sport Model

Every effort has gone into making the SUPER Y one of the lightest high performance P-30 designs available. Each kit has been assembled from select wood for a light airframe that can meet the minimum 40 gram weight for this event. It is an excellent transition model for free flight competition and just plain fun sport flying.

The SUPER Y is a derivative of the YARDSTICK model and has been optimized for P-30 and Small Mulvihill events.

As was its predecessor, the SUPER Y was also designed in the classic stick and tissue style of an Old Time stick model, but sized to use much less rubber motor stock and perform in a smaller flying site.

The SUPER Y is intended to supersede the YARDSTICK in principle. Thus we will no longer offer the YARDSTICK as a stocked kit We will maintain the web pages for those who have already purchased the YARDSTICK and for reference purposes. As noted in the YARDSTICK page we will offer short kits of the old YARDSTICK only by special request for those who still want to build one.

The SUPER Y Full Kit includes:

- Top quality laser cut balsa and plywood parts which have been fit checked and proven prior to kit production release.
- Quality select balsa strip stock.
- All components noted on the design including GizmoGeezer 9.5 Inch freewheeler prop assembly with assembly with setup hardware, Badge Classic viscous timer with actuator spring and all the finishing hardware needed to prepare the model for flight.
- CAD drawn construction drawing, instructions and Esaki tissue covering material.
