Does anyone have a photo of what the cowl actually looks like on the old scientific Golden Hawk? Its hard to see any detail on the blackhawk kit instructions....
Thanks,
Ryan

Peter;
I can not help you there. I have had similar questions on some of the other models. I have three of the original plans for the P47, Helldiver, and Curtis Goshawk, and they all have cowlings. Some made out of aluminum, others out of plastic. Anyone have the plastic P-47 Cowl?

Ryan and Leroy - I mold the cowls for the Scientific planes from fiberglass & epoxy.
It's quite easy and you can make any configuration you want.
Check out the attached picture of my Bullet and the cowl mold.

Great looking plane. Especially the cowl. What engine is that? It looks like it might be an OK Cub.
I might make a cowl for the P-47 I still have enough time. I have made them before using fiberglass and foam safe thin CA. They come out real light that way.

Hi, Leroy - it's an OK .049.
Here's another shot of the Bullet.
It's a great flying plane.

Bob;
What size prop do you use on your OK Cub? I could not get my OK Cub to fly the Fokker DR1, the engine runs great once you get it started, but it just wont pull the DR-1 around.

Leroy - as I recall, it's a 5-4.
What does your DR-1 weigh?

Bob;
I'll have to weigh it tonight when I get home. It was the first of the hollow Log kits I built from Black Hawk Models, and I built it following the instructions. Which didn't indicate that you needed to hollow it out more. So it is probably to heavy. I really hollow them out now. I should mount the OK Cub to one of the newer planes and see if it will pull it around.

I used to have a URL to a site that had the rules For the Musciano meets but have misplaced it can anyone help me out?
The question I need answered is, is it OK to glue up more than one block to get one the size needed or must you start with a block of the size needed? I know you can't form or glue up a fuselage or glue one up, but Sometimes it is hard to find a Block of the size needed.

Tom,
The short answer is yes. You can laminate blocks until you get the size you need. I have cut and pasted an exerpt from the NVCL Musciano Rules. Since we were the first group to do this, most everyone follows these same rules.
Section 3 of both the Acceptable Designs section and the Aircraft Requirements section should give you the answer.
"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 permissible planes (permissible to the best of our understanding) will be published separate from these rules. However, being on this list does not exempt them from satisfying any of the requirements listed in these rules.
2. Either single or twin-engine models are permissible.
3. Only carved fuselage planes are permissible. No profiles. No built up from sheeting and bulkheads.
4. Only planes with solid wings are permissible. This also means exposed controls only; not embedded or enclosed controls.
AIRCRAFT REQUIREMENTS:
In addition to the General specifications:
1. Planes are to be built per the plans except as permitted otherwise in these rules.
2. The size, outline, placement, and areas of the original are to be maintained. This includes the Wing, Stab, Elevator, Rudder, Fin, Fuselage Side and Top views, etc. Cowls (or landing gear), if included on the plans, may be left off; but will be not be scored as high in the Appearance and Craftsmanship event as the same plane with a cowl (or landing gear) that is otherwise equal. Cowls (and landing gear) may be made removable and left off in the flying events and doing so will not forfeit Appearance and Craftsmanship placement awarded while they were in place for Appearance and Craftsmanship
3. The fuselage must be carved from a block, or constructed of glued and carved slabs — no sheet and bulkhead or stick and tissue substitutions. Rounding and shaping of the fuselage must match original
4. Wing outlines must be maintained; the construction must be of solid wood; however, the airfoil is at the builder's discretion.
5. Modern control systems, hinges, and adjustable leadouts are permitted.
6. Finish and markings are at the builder's discretion. Colorful, elaborate, multi-color, finishes are encouraged. "
Hope this answers your question.
Take care,
Ron
