No not really. . . It's the swept back bent angle of the 767's elevator themselves that makes connection them to one servo rather difficult.

. . . . Not impossible. . . But difficult.

If youre going to use seperate elevator halves, it might be better to use torque rods on each elevator as I did on my C-5. Pretty easy to setup, even with a sweep back and in my case, annehedral.

That looks good and will work for your Galaxy . . there but might be a tad tricky in the tail section of a 767. . . Or maybe not. . . .

. . . I tried this several years ago with a fighter and my BAC-111 & couldn't get the elevator surfaces to ling-up or move the same amount on either side.

But for these MD-80's and bigger Mad-Dogs the flying tail arrangement should suffice.

maybe it can work, but i think that if i use this system, i will make it very very perfect and accurate to avoid what happened to you in your frieghter and BAC-111 thinking in all possible variables. But Chris, beware!, i do not say that you've done wrong, simple just didnt work, i imagine. You're a mentor, your advice is highly valued

The truth is until i doesnt work with the fuselage and tail, everything are ideas and fears in order to not lose time and money. Well...in a lot of parts of ours lives, time is money.

lots of people have ideas & advice & experience here on RCG. . . That's why I never think I know everything about RC flight. . . Because I don't.

In the end the only real way you can't test an idea is to test it in flight.

it was the maiden "Hop" of my MD-80 that showed me I needed a greater sized elevator on these flying pencils. . . I really learn things during flight.
