The International Cessna^® 170 Association

My personal opinion follows. I try to avoid attaching unrelated items together because it amplifies the amount of work required by a job. If I have to remove my glove box to access the engine instruments or vacuum hoses above it, I really don't want to have to mess with an Adel clamp, especially while working on my back under the panel. For the throttle cable, I'd try an electronics chassis cable mount with a zip tie, or something that can be easily disconnected and reconnected.

The problem Cessna faced with this and similar airplanes was the need to mount a throttle near the centerline so that both pilots could conveniently operate it… yet also needed to have the flight controls accessible from both front seats, yet use a centrally-located “joystick” to operate elevators and ailerons….that “joystick” being activated by controls directly in front of side-by-side seated pilots (formerly dual pilot seats were seated in tandem.)

Unless a complex and heavy system of levers and/or pulleys were used to reach a carburetor centrally-located…. then a Bowden type cable is what made perfect sense for simplicity…and it needed to be routed circuitously around that T-shaped “joystick”…. and held in a secure manner. I don’t have a problem with their solution. It’s worked for 70+ years unless someone failed to maintain it as-designed or modified it without understanding why it was originally designed.

McFarlane Throttle Cable MC0411091-2 uses "wedge washers" that angle the cable slightly to the right.
