Archie,

I wouldn't make it too oval shaped near the stab, profiles are notorious for not keeping stiff in squares and triangles.
I hope this helps some..... I have been off line for about two weeks with technical difficulties.

Here is the AMA CL General rules on profiles. I also include a graphic of the fuse width. Notice how CL PA isn't included in the table at all, so to first order, anything goes!. However as Mark points out , all politics,  umm I mean profile rules are local, so if you want to particularly fly in P40-like profile events (a non-rulebook event), you might want to check around you. I think a relatively safe version of a P40 "legal" profile is to keep the engine under a 40, and width on the order of 3/4", except at the nose where AFAIK, a doubler or even tripler is routinely allowed.

Also I don't think profile is even defined in the current PA rules section.

so from CLG-6 page of CL-general rulebook (2009-10)

 10. Profile Definition.  The fuselage of a profile
model resembles that of a conventional airplane
in the side (profile) view and appears as a thin
flat sheet in the plan (top) view.  When a
conventional, single cylinder, internal
combustion engine is used, the engine shall be
completely exposed from the centerline of the
crankshaft to the top of the cylinder head when
viewed perpendicular to both the crankshaft
centerline and the cylinder centerline.  In the
case of internal combustion engine with multiple
cylinders, the preceding rule shall apply to all
cylinders with allowances made by the officials
for appropriate mounting of the engine.  No
fairing may be added to the engine which
violates the ―completely exposed‖ requirement
of the previous sentences, and the engine
cylinder shall not be contoured to present a
streamlined cross section to the airflow.  
Additional reinforcements such as plywood nose
doublers and cheek cowls or fairings are
permitted within the width limits defined in the
accompanying table.  Such additional fuselage
reinforcements may extend from the prop drive
washer to a point 25 percent of the wing root
chord back of the wing leading edge at the root
and may be faired in.  Cheek cowls used in
Racing events may be of unlimited width, but
may be used only on the side opposite the engine
and only on models with side-mounted engines.
In the case of inverted or upright engine
installation, engine mounts may protrude from
the fuselage sides beyond the width limitations
of the table.  They may extend no further aft than
25 percent of the wing root chord back of the
leading edge at the root.  Any such protruding
engine mounts shall be of constant cross
sectional shape and dimensions, without
tapering.  The rear portion of those mounts shall
terminate in an angle of at least 45 degrees to the
longitudinal axis of the fuselage unless they
terminate within the wing structure.  Nacelles, as
used on multi-engine models are subject to the
requirements of this definition.  

Arch, I realise that I'm a bit prejudiced, but may I suggest a long look at Brodaks version of Gordan Delany's Pathfinder. Possibly one of the best flying profiles available today.

Arch,

Aside from the Pathfinder.. who knows?

You are a very good flyer, and I think that you will very rapidly tire of the profile and want a better airplane. You don't need training wheels. Believe me it comes back fast. Then you need something help you get fine tuned..

Why don't you build something with a simple fuselage, uncowled?

The Adamisins are known for their airplanes, I am sure that you can come up with a new one for the purpose.

P.S. Welcome back!

Archie,
I dont know of any restrictions on mounting controls internally. I have seen several done that way so why not? It does lend a bit more fidget work to what is intended to be a simple model, but hey your a modeler,, I say have at it.

Arch,
There is no reason that you couldn't have the controls inside the fuselage.

John D'Ottavio had internal controls in the "Topper" (Falcon Jr.) that he published. Ed Elasick won the 1961 Air Youths with it. Certainly that is a great precedence, and I doubt if that was the first time that it was done.

Add the blisters for the special elevator horn. I think that more people will admire the airplane, than be nitpicking it.

It will be great to see you flying again.

.......................While I'm trying to remember how to fly, would someone care to share a design for one of those hard point control handles. A sketch with a few dimensions should get me started. We've never flown with this type of handle so why not try it now, while we're doing some experimenting. Any  help would be appreciated. An unbiased, hard point handle might be something good to wake up these old brain cell. .............

Sent info., see your e-mail.

Wow,

A possibility of the entire Adamisin clan all at once at the Nats! THAT will be a HAPPENING!

You will have to include Todd and Marie also.

I sure hope it happens. Big Art will be beaming, and Betty will be smiling from above.

Regarding the internal controls...I'd suggest finding out what the local rules are. Whoever runs the contests that you'll be going to would be able to provide a copy. It's usually a club or regional association of clubs that writes the rules. That's to be absolutely certain you build a legal Profile for your area.

The Pacific NW started out with Profile 40 or "P.40", but too many newbies wanted to know what P-40 Warhawk kit was the best one to use. The reason for that was because many wrote it as "P-40", instead of "P.40". A few of us started a campaign to remove the engine size limits, simply making them what is allowed for PA (.91's!), and calling it "Profile Stunt". We haven't seen much change. A lot of folks are using .46LA's, and there have been a few ST G.21 .46's and G.51's, but not many. There was some bitching and screaming, but the rule change hasn't destroyed the event, and it's probably stronger than ever. There have been a few tuned pipe models show up, and a few more being built, but so far, none that weren't legal under the old rules. Our definition of profile is per the AMA rulebook as posted above...probably pretty normal practise.  If you'd like to see our rules, click here:

I met "Big Art" and "Little Dave" at VSC...y'all need to go next year!  Steve
