I’m putting the finishing touches on my 4 Star 40. I used Sullivan Gold N Rod control rods. Per the Sig building instructions (for the stock control rods) I trimmed off the outer Gold N Rod sheath where they exit the fuselage. Reading the directions for the Gold N Rod control rods they say the inner control rod should not extend unsupported more that one inch from the outer sheath, the span from where the control rods exit the fuselage to the control horn is about 2.5 inches. Would this unsupported span be a problem for the Gold N Rod control rods? I have an extra set of short metal control rods from the kit that I could insert into the inner Gold N Rod control rod for support, should I do this to stiffen the Gold N Rod control rods?

Also, I ran the throttle cable outside of the engine support, the throttle cable is at the correct elevation but about ¾ inch out from the side of the throttle linkage on the engine (a TT Pro 46) carburetor. If I use the solder-on threaded coupler and a plastic cleaves at the throttle arm (per the building instruction), the solder-on coupler rubs/binds against the engine mount. If I switch the throttle cable end for end and use a (metal) solder-on cleaves at the engine throttle arm the throttle cable is better able to make the bend to the engine throttle arm. However, Sig recommends against a metal-to-metal connection at the engine as it mat cause electrical noise that could affect the radio. I could also trim away some of the engine mount to smooth out the radius for the solder-on threaded coupler. I have about 1/8 inch clearance from the prop to the checks on the 4 Star. Suggestions?

Thanks,
