Try putting the pushrod from the bellcrank in the top hole in the flap horn and the pushrod from the flap horn to the elevator in the hole thats the same distance from the hingeline as at the elevator. That should give you a 1:1 ratio of flap to elevator.

Bryan,

It appears that you are using RC type clevis connectors at the flap and elevator horns.  If so, I would very strongly suggest that you slip a short piece of fuel line over the locking clip to help insure that the clevis cannot come open.  Yeah, I am a belt-and-suspenders sorta guy......

Cheers,

Your right Bob that is how my belcrank is set up.  I like your idea better and will use that belcrank setup on my next plane build.  The Horns on the flaps and elevator are from the Windy Urtnowski's Brodak Cardinal Kit.  But i did go
with a Ball Joint on the belcrank to 4-40 rod out to the flaps using a great planes 4-40 threaded coupler soldered on
tight.  Coming off the threaded coupler is a du-bro sping stell kwik-link connected to the flap horn.

Leaving the flaps with 2-56 du-bro kwik link safety lock , connected to a Dave Brown fiberglass pushrod system.
Where it meets the elevator Horn with another du-bro safety lock. I really like the looks of the pushrod system
with the du-bro safety locks. And they do have the slide safety lock on the inside of the connectors in the pictures
you cant see them.

I am a beginner at the lines, But i am reading and studying alot .  Thanks to this site and all the feedback i am
learning twice as much.
