What would be the best pushrods for a 40 size aircraft?

Basic flying with some hard aerobatics.

I have some Dubro Lazer pushrods and some Sullivan gold-n-rods.

Also, has anyone tried those Lock Kwik Links? if so, how good are they?

Thanks

I like fiberglass or carbon fiber arrow shafts for pushrods. Especially in smaller planes where I don't want to support the push-rods through the fuse.

I tried the Dubro locking links on a rudder pull-pull system and the threads pulled out. Plenty of others have been using them successfully. I won't try them again. I like the gold Sullivan links with the locks and jam nut.

I use quick links on the servo end of everything. Get the ones (Great Planes?) with the stainless steel socket head BOLTS. They use a larger allen wrench and take more torque, biting the wire deeper. I use them up to .40 size planes ('cause I don't have any larger ones yet) and have not had one fail yet. I use the golden rods because I like the clevises they come with.

Depends on the aircraft and the length of the pushrod. 2-56 rod is usually sufficient for up to .60 size planes. Centrally located servos will need an outer tube that is secured in several places to eliminate any flexing of the rod. Short lengths of 2-56 rod are fine without an outer tube. Golden Rods are fine but long lengths sometimes tend to grow a little after sitting in the hot sun for awhile which can throw your trim settings off. I've used Du-Bro Kwik Links and like them. You have to be sure to use the correct size as they are made for 2-56 and 2MM as well as 4-40. If the 2-56 Kwik Links are used on 2MM rod (which is typically supplied with ARF's) they could strip loose.

Swager,

Is this for your 4*40?

Sullivan Flex Rods (braided cable) are very nice where you can use them; they have the flexibility of the gold-n-rods but don't grow or shrink like the plastics. The Sullivan gold metal connectors or their ball link system with the spring lock works really well (use a lock washer on the ball connector) which I find extremely handy for throttle linkage.

I've also used a Dubro connecter that is black plastic, but the little rods on the end are steel (not sure what they're called)-- they are excellent and don't have the play in the servo arm that the all-metal connectors sometimes have. Very smooth.
