I'm having a tough time precisely bending the push rods for the rudder and elevator in my Nexstar; the directions have you install everything, then bend the rods and attach them. What tool do you use to do this, as it has to fit inside the 'cockpit' and make a crisp, 90degree bend.

Also, what do you think about using automatic transmission fluid instead of after run oil?

Thanks.

For the metal push rods it just takes some work, no special tool other than your thumbs and general hand tools (pliers, a vice, etc.). For after run oil I use Marvel, but only when they will be stored for more than a few weeks. With modern synthetics and blends in the fuel after run oil is not as crucial as it once was.

I have a pair of flat nose pliers. You can get them at most hobby shops or at a Radio Shack or any electronics supply shop (not electrical, but electronic). Another method is to put the wire in a vice and tap it with a hammer to bend it over. It will bend nicely to 90 degrees.

After run oil isn't a debate.. you just use it or not. Your choice.

They do make special tools for bends in wire, I have seen z-bend pliers ect....I have only used regular pliers and needle nose for really tight spots.

I have used ATF, Castor and the special afterun oils that come in the really small bottles. My supply of Marvel Air tool oil depleted last year and now I use K&N which is basically the same as Marvel. THe actual oil is less important than getting a sufficent quantity into the engine and making sure that the engine is run out of fuel prior. I add enough....tablespoons to the motor until it is coming out the top at least twice.......Maybe overkill but that is what I have been doing.

K. Thanks guys.

Installing the pushrods in the NexStar is pretty easy. The threaded ends with the clevis goes to the elevator and the rudder control horns. The end attaches to the servo arm with a "Z" bend or and EZ connector. If you use a "Z bend" pliers, screw the clevis on until the rod extends completely thru the clevis. This will give you a little extra room to make fine adjustments to the surfaces.

By the way, I have found Z bend pliers very helpful when installing pushrods. I use to be bend "by hand" but found this tool more accurate and faster.

Happy Landings!

I'm pretty sure that the After Run Oil sold by Hobbico is actually automatic transmission fluid. If not, it sure looks like it. You have to admire their ingenuity selling ATF oil for $2.19 for 2 ounces instead of $2.19 for 16 ounces.

You don't need to bend them inside the airplane. Bend the servo end then stick the threaded end (sans the clevis of course) through from the inside of the airplane.

I have even gone as far as inserting the control rod in through the hole for the fuel tank after bending when I couldn't get enough room to come in any other way on a tight installation.
