Hello,
I just bought a new built plane and the builder used the screw down connectors to attach the wire from the push rods to the servos. I usually use a cleavis to connect to the servo.
Are these screw down connects good?
It seeams like they could slip and cause unexpected problems.
Thanks

I only use these on a throttle servo, which has less stress and maybe at the nose gear. Wouldn't use it on a flying control surface.

Ive used these on trainers ,for all the surfaces and have never had one fail, although I have read of several failures from various sources.

I make checking them part of my ground check before each flight

I would however not recommend them for a faster more aerobatic plane . even though Ive seen clevises fail also !!!

I have used them for 10 years on everything on 60 size planes and smaller (even aerobatic models) without a failure yet.

I only trust them on throttles and nose gears. I use a good steel clevis or a z bend on flight control surfaces.

Hey guys thanks for the info.
Would it be safer if you ground down a small flat spot on the rod so the screw sits flat on the rod?
Thanks!

I wont use them for operating a control surface except with "Pull-pull" systems.

And yes, definitely cut a flat for the setscrews. Never had one come loose with a flat.

Without a flat ANY setscrew has a greater probability of coming loose.
