Throttle/Mixture bracket for Precision Servo/Superior Induction?

Well Known Member
I can't be the first person to need this. I can fab if necessary, but asking first. Precision Injection Servo on an IO-375. There are those two suspiciously handy places on the Superior Cold Air induction where it seems like a cable bracket could be secured.

Is anyone offering a throttle/mixture bracket for this set up?

Clay,
I think what you need is this?:
https://showplanes.com/Category/Brackets
The Throttle/Mixture bracket and the angle(s).
I used it on mine, had to trim it a bit to clear the Vetterman muffler.
I have no mixture cable, it's electronic.

Okay, yes. I've seen that on the Showplanes site. I'm doing their Fastback mod as well as their cowling.
It appears as though that bracket only holds a single cable? Is that right? Would it be possible to use two of them, and so have both throttle as well as mixture cables held?

Don't believe the Showplanes bracket will work with the Precision Servo. If you look at the photo on their site, they show both mixture and throttle on one bracket - but its routed to an Airflow Performance servo. The Precision servo has the mixture on the left side and the throttle on the right side of the servo body rather than the bottom like shown in the photo of the AFP servo.

I had to custom make brackets for both controls on my IO-375. In the case of the mixture control, I bought the Vans bell crank bracket kit but only used the actual bell crank out of it. I custom made the actual bracket it mounted to. IIRC, I also had to shorten the mixture arm on the Precision servo and rotate it 180 degrees on the shaft (basically pointing up instead of down).

There are probably other ways to skin this cat - but I suspect you will be fabricating.


EDIT: Found a couple of not-so-great photos of my two brackets.

The word back from Showplanes is "No." Their bracket puts both cables on the same side, while I need something that puts the cables on opposite sides.

Pondering...
