Objective:
To have a nostalgia control line event, and to honor Walt Musciano, who for many of us, designed our first model airplane. The emphasis is on fun, not performance, on nostalgia, not competition.
Remember the one and two page Scientific spreads in the model magazines of the 50’ies, and 60’ies, lots of little carved balsa fuselage/solid wing semi-scale designs that almost fell within your nickel and dime budget? The purpose of this event is to let you go back to that simpler time, indulge your nostalgic bones to the maximum, and at the same time honor the man who designed most of those models —- Walt Musciano. The rules are designed to keep within the spirit of that time, not making them into modern designs with modern engines/performance, but to recapture the wonder of flight of the youthful initiate back then, and to savor it again after all these years.
General:
All events will be conducted in accordance with AMA regulations regarding control line models and the particular event being flown, except as is otherwise specified in these rules.
Acceptable Designs:
1. Must be 1/2A (.049) control line planes designed by Musciano and kitted by Scientific. It does not need to be built from the kit however. A list of the permissible planes will be published separate from these rules.
ENGINE REQUIREMENTS:
The limited engine rule is intended to maintain the nostalgia spirit of the event and to keep the performance comparable to those that were built back then.
1. Engines must be .049’s or smaller.
2. Only those from the list below are allowed.
3. Only stock parts (as delivered on the engine at the time) are allowed, no hop up or high compressions heads.
4. Only suction fuel systems are allowed — no pressure.
5. Engines may be freely substituted on your plane between attempts, heats, officials, finals, etc. However, once you use an engine in an event, even if only an attempt or a "did not finish" heat, then no one else may use that same engine in that same event.
Eligible Engines
Atwood: Wasp and Cadet 049s only (no integral plug heads, no Atwood Signature, Atwood Shriek, or Atwood Shriek Signature engines).
Cox: Babe Bee, (only the old model, single transfer port, low compression head), Space Bug Jr (single transfer port, low compression head), Golden Bee (single transfer port, low compression head), and Pee Wee .020. Modern Cox low compression heads are acceptable for Babe Bee and Golden Bee engines. For the Space Bug Jr., use an original plug or an original plug bored and taped for a regular 1/4 32 screw in glow plug. No other plugs are acceptable. Currently manufactured Cox engines are NOT eligible. This includes Babe Bees, Black Widows, Killer Bees, Venoms, etc.
Fox: Fox .049 (not the large case/intake F.A.I. model).
Holland: Wasp .049 only, not the Hornet.
K&B: K&B Infant, Torpedo .035, Torpedo .049, and Sky Fury .049.
McCoy: Any McCoy .049, either Glow or Diesel. Does not include the plastic case Testers/McCoy engines
OK Cub: Any OK Cub .049 (or smaller), either Glow or Diesel.
Spitfire: Baby Spitfire .045, Spitzy .045, and Royal Baby Spitfire .049.
Testers: Copy of Wen Mac Hotshot .049 only.
Wen Mac: Any Wen Mac .049.
FUEL:
Club standard 1/2A fuel (15%), supplied by the Club, must be used for all glow engines. Diesel users must supply their own fuel.
LINES:
1. Steel stranded cable, minimum diameter of .008”.
2. Alternate line material: Spectra, a good brand name is Spiderwire (fishing line), 20 lb. test.
3. Length: 35 ft. from center of plane to center of handle grip, + 6”, - 0" tolerance.
LESSONS LEARNED/HINTS
1. Keep it light.
2. Run in your engine before the contest.
3. Test fly the plane before the contest, make sure engine, fuel system, and trim are working/correct.
4. Use tip weight on the outer wing, even though the plans do not show any. Start with 3 pennies or equivalent for .012 inch diameter stranded steel, 2 pennies or equivalent for .008 inch diameter stranded steel, and 1 penny or equivalent if you are using Spectra, or Spiderwire. Adjust the tip weight as necessary for best flight performance.
5. Start off with enough line rake so that the nose hangs down just a little when held up by the leadouts. Adjust line rake as necessary for best flight performance.
6. Start off with the Center of Gravity at 20% of the wing chord. Adjust the CG as necessary for the best flight performance.
7. Start off with about 20 degrees maximum elevator deflection (throw) each way. Make sure the elevator throw is equal up and down. Adjust throw/(rate of deflection) as necessary for best flight performance.
8. Do not over prop -- let the engine rev. A 5-3 is good for a Cox. If the plane is light you might get away with a 5-4 for racing and speed (Cox). Some of the non-Cox engines might work better with a little more prop, but it won't be a lot more. Try different props and see what works best. Test with a stopwatch for racing and speed.
9. Set the needle a little rich, a little burping, until you know what the best setting is for your combo.
We had lots of fun last year, come on and join us
