Well I got my hog almost finished up and am installing the servos and push rods and liked the way the Hog Bipe's improvements were that I built so I incorporated some in the AH. Anyway I liked the plastic sleeved push rods so I did the same but instead of having the thicker ones like the Bipe I bought and installed Sullivan goldenrod pushrods # 505 which are blue sleeves and yellow inner rods and sanded them off flush with the sides of the fuselage to look nice and clean like the Bipe. Well problem is that you are not supposed to let the inner rod extend out any farther than an inch out of the outer sleeve and mine both for elevator and rudder are an inch and a quarter or more. So as I was thinking about how to fix this (and it might not be that much of a problem anyway) I was considering inserting and glueing a short piece of piano wire into the inner rod extending into the outlet (of the fuselage)of the outer sleeve to stiffen it up a bit. Anyone see any problems with that? Or I could just go ahead first and set it all up without it first to see if I have too much flex on the rods from deflection resistance. How much is an Astro Hog going to have anyway, its not going to be a 3D model and if all else fails I can fish some wire through and us a pull pull system. What do you think? Looking back I should have used the largest nyrod or golden rod I could by because of the distance from the outlet holes to the control surfaces. Thanks for any comments.

Hers a fix that might work. Pick up a piece of 2 56 rod and let some of it extend into the tube . It will still thread into the end of the rod.

I think the best way to fix it is to take the same 2/56 and screw it into the nyrod. Great Planes makes a connector for the control horn that the other end of the rod will fit into and then screw the set screw down tight and you are done. Another method to fix it is to get some 36" long pieces of 2/56 rod and use the outer nyrod as a guide and just replace the inner nyrod with the new 2/56 rods. You can only do it this way if the outer rods in your plane are close to being straigth and there is no binding on the metal pushrods once they are slid in. I gave up using Nyrod years ago because every flight, the plane needed to be trimmed. It was because the Nyrod would expand and contract depending on the weather. Hopefully over the years that has been corrected. Good Luck, Dave

Wow, thanks insane. I never dreamed that the threads were raised and always assumed that they were the same as the rod they were on. Worked like a charm. Thanks for the response. The pig will be flyin soon.

David.. I had the heat expansion issue myself back in the 80's with ny-rods.
You could watch the surfaces move as the plane adjusted to the weather.
The ones I bought last year don't shrink and grow with the weather like they used to.

I make my own custom length rods..
I get the 12" push rods with one end threaded..
I use the pre threaded end for the clevis

I cut to the length I need and tap the other end with a 2-56 die..
The rod diameter is to small to use the tapped end for a clevis but with a little gorilla glue it'll hold solid in the ny-rod.

i just used a 12 inch threaded rod and cut it to the length i needed.
