Rudder time

Fred, are you using only one half of the Robart hinge pin to make a removable rudder? Does the long rudder pin ride in a tube?

The full size Gull that I used to help rig had a light blue fuselage with blue leading edges and white on the open structure.
From memory the blue was "Ford Olympic Blue"

How does this happen I press submit and I already have your question. Ghosts

Yes I cut the hinge in half and also remove the little flanges. I do this with the small and the large. There is a small one at the top of the rudder because there wasn't enough room for a large pin. Yes the 1/32" Music wire is the axle inside the small plastic tube. This is all assembled with the pins protruding from the rudder and then is glued into appropriate holes drilled in the fin post. Once the glue has dried(epoxy) the pin or wire can be removed and the pins stay in the fin post in perfect allignment.

Thanks , but I am going to give this a varnish finish and I'm thinking of copying the Derby and Lancs club gull with the old canopy, BGA 378 with the blue and white stripes on the rudder.

The master class continues!

All great stuff Fred, and thanks so much for your effort.

I guess you'll already have checked out the Gull on the scalesoaring website:

Yes I have. Unfortunately, just about all the pictures or photos of the Gull are in black and white.
If anyone can tell me what shade of blue is on the rudder of the Derby and Lancs Gull or for that matter, if they continue the trend, on their present gliders, I would appreciate it. Or is the Club still in existence?

Thanks Fred

Hi Fred,
Are you building in time with your posts, I am really enjoying this thread, you are a craftsman of note. I am almost convinced to build a wooden glider next and hang up my latex gloves.

Regards
Mike

Don't you know it......don't get me wrong...I love to fly...but spending time in the shop cutting and fitting and figuring out how to make it all work is why I scratch build vintage wood airframes.

So true, so true. I just wish I had enough original scale vintage sailplanes built to say so.
A truly interesting and yet, one for the truth kinda conversation I have had with an established F3B flier here in Japan.
Him: A soarhead like you with a mind set for thermal flying. How come you arent flying F3B.
Me: 'Cause I want to BUILD my own planes.
Him: Silence. A bit each of surprise, shame and embarrassment on his face. AND!!! not to forget, AND!!! must not be left out, NO!!!!! a true expression of understanding on his face.
We ALL Enjoy model airplanes. ARFs are the last realistic resort. Building RULE!!!!

Fred, a question on your skid shock mounts. Are you first mounting the bits of rubber tubing to the fuselage lower keel with small wood screws? I assume two so it won't rotate and to make it easier to reach inside the tubing with the screwdriver tip, then mount the skid to tubing with a bolt and nut to make the shocks functional?

It seems to me a single screw all the way through would have the possibility of breaking out without this method and curious as to how you solve this.
