Electric motor with switch harness
 

Hi.
Do they make switch harnesses for electric planes so that I do not have to constantly unplug the battery pack to "turn off" the equipment?

Some ESC's (electronic speed control)with a built-in BEC (battery eliminator circuit)(regulator)come with a slide switch already installed that will disconnect it from the receiver disabling the planes controls and throttle until the switch is turned on. This won't keep the battery pack from being drained. They also make a battery disconnect switch or safety switch that disconnects the battery from the ESC until the switch is plugged in(turned on).

An arming switch, right (pictured). But what I do not understand is how it plugs into the battery pack and ESC.
Battery packs I see usually have a two-pin connection, and no receivers I know off take a deans plug.
So how would you plug the battery pack and receiver into the deans plugs that are on the arming switch?

What kind of plane and what size battery pack are we talking about here? JST on a LiPo pack is typically for very small 2 or 3 cell set-ups.

The arming switch installs between the battery pack and the ESC like in the diagram below(disregard the BEC connection and clipping the red wire if you don't have a BEC)

Here is an ESC with a switch

1/2A scale. A Livewire Jr Champ converted to low-wing, and a Berkeley Brigadier.
And a Great Planes PT20

Arming switches are typically used on medium and larger planes using higher amperage set-ups. You would have to make an arming switch with JST plugs and connectors, or install an ESC that has a slide switch.

That would require quite a bit of complicated soldering. I think I will need to continue with the unplugging of the battery pack. Why can't anyone invent a switch harness for an electric plane?

Not sure where to get a ESC that has a slide switch. You said in a post above that this would not stop the battery pack from draining, which kinda defeats the purpose of having the power switch. And constructing an arming switch with JST plugs would be too complicated for someone with basically no soldering skills. So I will have to keep going as I have been with unplugging the battery pack. Thank you for your help.

Do they have adapters that can make a deans plug into a JST plug that could simply be plugged into the arming switch?

Could these adapters

be used to convert the deans plugs to JST? But then you said something about the 1/2A scale planes not using high enough amperage set-ups to use the arming switch.
This is all too complicated so I will keep things as they are. Thank you.

For a 1/2a plane it's a space issue plus the added weight. You could install a slide switch connected between the red wire on the ESC's cable that plugs into the receiver.

I am a total novice when it comes to soldering. Does anyone have any graphics on how to do this in simple-to-follow details?

Ah? Does throttle cut switch do the same?

Throttle cut switch as in programming a throttle cut switch on the transmitter? If so then no. Throttle cut on the transmitter moves the throttle servo and pulls the throttle closed from idle position on a glow or gas engine. It would not work on electric set-ups.

Oh yes it works. Throttle cut in the transmitter of an electric plane effectively makes the throttle stick inoperable so you can't accidentally hit it and make the unattended plane move forward.
All the other surfaces will move if the receiver is powered with the same battery as the ESC

Only my heli radio can program that switch to a 2-3 position switch . My other plane radios have it only on a momentary switch. I'll have to try that and see if it works in a similar fashion like throttle hold does for helis.

I'm telling you it does. I have my Dx18 programmed with throttle cut on all my 10 electric planes. Safety featured.

OK . I just programmed a plane on my heli radio and programmed a mix for thro-thro @ -100/-100 and set it to a two position switch with the offset maxed out @-125 and it works .
With the switch ON the plane is active all but the throttle. Turn the switch off and the throttle is now active. Very similar to heli throttle hold.
SHD3920, depending on what radio you are using you may be able to do this

Yup, I'm gonna try it too. I have a 12Z, so finding a switch won't be a problem.

If this works, it will be a real problem-solver.

.

If you're on a heli radio, why not just use Throttle Hold?

The plank software on the 12Z has Throttle Cut, not Throttle Hold. I suppose I could re-program all my planes to the heli side, but then I'd have to figure a mix for aileron differential, etc.

Anyway, I'll try Throttle Cut tomorrow.

.

The radio I use for helis. Model is set up as aero not heli. TH only come up on helis models....not on aero models.
Anyway on the other radios I never tried to advance the throttle on the glow/gas planes when the throttle cut button was pressed but it does make sense that it shouldn't advance. Will have to try that and see if it works and if it can be programmed off to a 2-position switch . Otherwise a thro-thro mix should work.

No chance. I have a simple JR Max6.

I think your best bet would be to install a slide switch in the fuselage and wire it into the 3-wire cable on the ESC that plugs into the receiver. Cut the red wire and connect the switch in between.. When you install the battery pack and plug it in with the switch off the plane is not active. When you are ready to fly turn on the radio then turn on the plane(like a typical glow/gas) and then the ESC and motor will arm and the plane is ready to fly. When done do the reverse. However do not let the battery plugged in for long periods of time with the switch off as the ESC will drain it.

This is exactly what I am looking for.

So I can turn everything off when not flying, just like a nitro plane. If the battery gets depleted if not unplugged that must be the same thing with a nitro plane. If the battery is not unplugged from a nitro plane it will get depleted as well. So basically with every plane when it is not being flown the battery should be unplugged. But that also goes for battery that is just sitting on a shelf, even with it being unplugged it is STILL being depleted somewhat.
This switch would be perfect, I just want something to turn off when not flying. Or when working on the plane.
