BlueMax 3 :Like the name Max for some reason! Here comes what I do ! Use your 4-40 rods ,I use Sullivan Golden clevises,(the ones with little clip)First put 4-40 nut on threaded end , then gold clevis, this is surface end. Take a bit & drill threads out of clevis so rod will fit in , adjust rod to length cut & solder on , this is servo end. Center servo & surface , adjust rear clevis , tighten nut up to clevis to lock(stops thread wear in clevis, install lock clips on both ends. The reason I drill threads out is they don`t make a solder one with clip. DuBro now makes a clip one ,but I just don`t like threaded ones at both ends (plastic don`t solder good ). A trick I learned with DuBro ones is just buy 2-56 ones, drill out to fit 4-40, you only need to keep one size ! Every thing is tight thus no noise for radio. I like this on IMAA ships as z bends get big with 4-40 rods . Happy Landings big max 1935
