Built in dihedral on tubes
« on: May 09, 2012, 06:22:03 PM »
This is a first for me. I have built on tubes/rods before, but never with dihedral. I am building a Profile Bearcat, huge one, and the wing has dihedral. Using the same method used by Al Rabe for his planes.

Looks like it should work -- what's the tube material?

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

Ty,

You build neat, or do you clean up for the photos?

Power?

58" is not small.

The F8F isn't my favorite Warbird, but as the aircraft Al Williams used, it's close to the top of my list.

Great airplane and here's a nice scheme. It would be my first pick for a F8F.

Pat Johnston has used this method forever. Pretty easy if you have laser cut ribs.

Aaron cut the ribs and punched the jig holes, himself, for a Classic Legal Rabe Bearcat.  Since then I have gotten laser cut ribs from Kyle for a Rabe Mustang II.  It really works well if everything is lined up correctly.

Charles

It's already been done, many years ago, by Keith Trostle.....and quite successfully, as evidenced by his many wins in local, regional and national (Classic) events with the Al Williams paint scheme.

You got that right. The tubes tend to be in the way at times. But talk about a straight wing. Only foam, lost foam or kept foam are as straight, but not as much "fun".  H^^ D>K

TY,

I never built a straight wing in my life. Even when I was cutting foam.  n~

Mike,

My favorite paint scheme on the F3F-1 actually the G22 flown by Al Williams. I have the fuselage framed up from an old Aristo Craft kit. I had Polks also but sold that eons ago. :-(

Well, not really framed up, but started.

If I had money I would commission you to paint the G22 for me. You do good work. Do you trade paintings for graphics? Didn't think so.  n~

Ty, I sure hope you pick that scheme.

Ty     I have seen several of those profile Bearcats fly and the heavy ones fly the best. One at 70 ounces flew very well. The lightest one at 55 ounces was more like a glider. That big flat profile needs the weight to push through the wind. Use a strong 60 on it. If you use the ST/60 you don't need the motor on the inside to get it to run correct . Have the head fins removed and the heat will stay in the motor and it will run in a strong four cycle. The motor will not over heat. #^
