Lines, pull test change approved for F2D Proto Speed

Revises specifications for new event

Ken Burdick proposed a change to the Northwest F2D Proto Speed rules. This proposal grew out of the experience of F2D Proto Speed flying in the first two years of the new event. Fliers discussed this at contests in 2009. The proposal brought F2D specifications more in line with national Speed event practices.

Results of the voting are as follows:

1. Pull test: The proposal changed the Northwest F2D Proto Speed pull test from 25 pounds to 24G. The proposal also added a maximum model weight of 23 oz. This proposal was approved by a 100% vote.
Lines:
This proposal changed the flying wires from.015 stranded steel, 52 feet 6 inches in length to .014 solid music wire, minimum 52 feet 6 inches. This proposal was approved by a 100% vote.


Voting

The voting was conducted from Nov. 16, 2009, to Dec. 16, 2009, according to the process described on the Northwest Rules Page. If you have any questions about the process, e-mail the rules coordinator.

NORTHWEST F2D PROTO SPEED RULES

1. PURPOSE: This event is intended for all fliers and pit crews interested in a simple Speed event which uses unique airplanes of a set wing area and profile fuselage, that is restricted to FAI F2D-legal engines.

2. All AMA control-line unified speed rules apply, except as follows:

2.1. Airplane and the entire control systems shall undergo a pull test of 24G.(25 pounds). Maximum model weight shall be 23 oz.
2.2. Lines are .014 solid music wire.(015 stranded steel.) Wire material shall be the AMA-required ASTM A228M spec wire. Minimum length is 52' 6" measured from the center of the handle to the center of the fuselage.
2.3 Minimum wing area not including the stabilizer and elevator shall be 100 square inches.
2.4 Airplanes must have a vertical tail fin.
2.5 Airplanes must have a canopy. Wood canopy is allowed but must have a colored outline defining the shape.
2.6 Airplane must have a two wheel landing gear with minimum diameter wheels of 1 inch. Wheels must be spaced at a minimum of 2 -1/2" apart.
2.7 Airplane finish must include a colorful pattern or be painted a solid color. No all-clear finishes will be allowed.
2.8 Airplane must have external controls, the centerline of the bellcrank may be centered inside the fuselage but the bellcrank must be exposed when deflected.
2.9 Terminations of the lines to a bellcrank must be double loop construction when used with a metal-to-metal contact.

3. Engine: Any design or make of piston glow F2D -legal engine is allowed, maximum engine displacement is limited to .1525 cubic inches (2.5 cc) . Modifications are limited to removing material from the engine only. (diesel legal F2D engines are note allowed)

4. Muffler: A current and legal F2D muffler must be used on the engine. No modifications are allowed to the muffler

5. Fuel tank: Any design of fuel tank is allowed, including pressure systems.

6. Fuel: Glow fuel shall contain a maximum of 10 percent nitromethane with 20 percent lubricant and the rest methanol. Glow fuel will be supplied by the contest management.

7. Timing: Timing will begin from the release of the model and end after eight (8) full laps have been completed. The pilot will have 1-1/2 laps after release to get into the pylon.

8. Flying handle: Adjustable handles are allowed.
