Finishing my second H9 corsair , measured everthing carefully before glueing the elevator halves to the stab but after it dried a test run on the ground appears to have one side with a slight differance then the othere when I move them up and down .
The side with the control horn attached will always move more since it's connected to the servo. The other side will trail since it's receiving input from the first side.
I like to use Sig heavy duty elevator joiner, part #SIGSH554: [link]http://www.sigmfg.com/cgi-bin/dpsmart.exe/DetailProduct.html?L+Sig+mnvh0519+_Dimagefile_02SI GSH554_2ehtml_01[/link]
It has a single internal control horn so torque is split evenly between the two elevator halves. My H9 Corsair has it and my TF Corsair has it.
