Connecting ACT to ESC

[renard80]

While repairing crash damage on my HZ SC, one of the ACT wires has disconnected from the ESC, and I don't know where to reconnect it.

When looking down onto the ESC, there are three small plugs grouped together - two of them are side-by-side, the other is in front of them.

My "bottom" ACT wire is still connected to one of the side-by-sides.

Please can anyone tell me which of the other two plugs accepts the "top" ACT wire (the one which runs from the top of the windshield)?

And from curiosity - what's the remaining plug for?

(Sorry if I haven't got the technical terminology correct! Still learning here, folks . . . )

It is the two plugs next to each other. The top one is the LVC Low Voltage Cutoff jumper pins, which with LiPo's should have nothing there.

In my opinion you should unplug the ACT, and remove the sensors from the fuselage. They really do more harm than good.

You did well. NOW > remove the other one.
ACT is BAD.
Unfortunate, I wanted it to work when I was learning too.

ACT works by using sensors looking at the ground and horizon. It differentiates shade (dark ground/light sky) and tries to keep them that way. If the plane goes up or down too fast and the shade isn't right it 'takes control' AWAY from you and essentially neutralizes the controls. You can achieve the SAME result just by letting go of the sticks. Of course new pilots don't they just over correct some more. The high wing Cub will self correct in time but not immediately.

If ACT kicks in up high, no problem, but then letting go of the sticks would work also. If it happens down low you have NO ABILITY TO CORRECT SINCE CONTROL IS REMOVED! Just like letting go of the sticks once you pointed it straight at the ground from 20 feet up it's going in! Its not useful down low and wrecks more planes than it saves, but it sure sounds good to new fliers. Since they can't fly anyway and they wreck anyway they figure it would only have been worse without it. They can't differentiate between their short comings and ACT's problems.

So it works up high where you don't really benefit from it and screws you up down low when it doesn't help. It also gets totally confused when you fly over water, snow or very light ground surfaces (light concrete, sand) since it doesn't know what to do with that. It's NOT SMART, it's just a shade sensor. What it does best is lure in new fliers. Great marketing scheme.

@skivit & flydiver

Your advice is greatly appreciated.

I wasn't intending to use ACT in view of its bad press here and elsewhere - but I was concerned about a loose wire floating about.

Thanks again to both of you.
