Fred,
Aha! It sounds like it should be pretty easy, just a dual termination =
of the control cables at the fuel servo, and two completely redundant =
throttle cables and knobs. Like a lot of things, it seems obvious once =
someone shows you the concept! I had it stuck in my head that the =
interconnect between the controls should be at the panel end, since I'd =
seen a setup like that with quadrants.
Keith

Dear Keith:
I have installed only a dual throttle control on my plane. The cables =
are connected in the engine and each run back on the right and left. I =
have run my cables and should be connecting them in the next few weeks. =
Scott Bakes should help you with how to do it, if you call him. I did =
not see the reason to run mixture and prop control.

Subject: REFLECTOR:Quadrants vs. push-pull controls
I'm getting things lined up to install my IO-540, and I'm trying to =
decide whether to go with the standard push-pull controls or the =
"cooler" quadrant option. =20
I recognize that the push-pull controls have the nice vernier fine =
adjustment and anti-creep. On the other hand it's not clear how to rig =
up dual engine controls with the push-pull scheme.
I recall Rob Johnson's post on his modified ACS homebuilder =
quadrant. Do any of you have a source for practical quadrants that lend =
themselves to dual installation?
Should I just forget the dual controls? =20
