Default RE: clevis or z-bend?

Your set up is fine with the exception of the throttle cable you got issues there as already mentioned. I prefer to avoid 'S' bends to exit a fuselage all together and they promote control blowback pushrod flexing but do prevent the pushrods from becoming a turn buckle. I normally use "Z' bends at the servo and a clevis at the control horn.

Those kind of clevis locks are a royal pain and you loose then in an instant. I much prefer the tried and true piece of fuel line. They are easier to install and last longer if you keep some Large size fuel line around for the purpose.


Those rolled metal clevis are OK but one with far less failure modes is the hayes plastic (black) with a metal pin, Lock nuts are not ever needed and the seam cannot spread allowing slippage on the threads under load. but don,t use this type of metal pinned plastic clevis on a throttle pushrod at the engine, Use only all plastic there if the throttle arm is metal.
