Wiring WTC of Subtech Albacore - how to wire apc3, on/off switch, bevr

[Guest]

I am in the process of wiring the wtc of my subtech albacore, and have a problem wiring up the apc3, and the on/off switch. Does the on/off switch connect to the apc3 ? (There are 4 wires running out of the apc3) Also, what else does the on/off switch connect to?

Secondly, how is the receiver powered? Using the bevr which is connected to the battery?

Thanks in advance

Hi John,

The APC (or just

Hi John,

The APC (or just about any pitch controller) is placed in-line between the receiver and stern plane servo. The SubTech APC will have one 3-wire pigtail coming out of it and one set of three pins...essentially making it difficult to connect anyway but correctly.

Most folks will place the on-off switch between the battery 'plus' and the BEVR/Spped Controller connections. This allows the entire boat to be turned off via the single switch.

Correct...the BEVR is meant to be used to power the receiver.

Jeff,

Thanks for your quick post,

Jeff,

Thanks for your quick post, I was able to connect the female parts of the apc3 into the wtc, however where does the "male" wire (it has 3 pins in it) go?

The on/off switch is not just one wire; it has two leads (one female, one male) coming out of the "off" side, and one lead from the "on" side. (female)

Which electronics connect to this?

Any pictures that you may have of this setup would be GREATYLY APPRECIATED!! (i am a visual learner )

my email is jpetrucelli@peddie.org

Thanks

The male connector goes to

The male connector goes to the dive plane servo. So as Jeff said, that places the APC-3 between the receiver and the servo, allowing you and the APC-3 to operate that servo for pitch.

Some people have more than one switch, yours sounds like a normal "flight pack" switch, used for a standard RX/RX battery/charging arrangement. I'm not sure it's very useful for this setup, I'd skip it. To completely power on/off *everything*, the switch needs to be in the battery lead(s), normally the positive battery lead only would be switched. This switch should have a current rating of several amps, 10A would be good, larger than a standard flight pack switch. Myself, I don't even have a switch, I have a Deans connector on the battery and just plug/unplug that...one less part, and you'll likely have a battery connector anyway.

I'm just not getting this...

I'm just not getting this... Can you explain this in a diagram, or an actual picture of the setup?

Bear with me, the directions for this step are very vague

John,

Which of the two topics

John,

Which of the two topics are you in need of help with?

For the APC-3 (not the APC-4), there should be two 'servo pigtails' coming out of the box. One will be a female plug and the other will be a male plug. The servo should have a female plug on it.....this would be plugged into the APC's male plug. Now take the female plug of the APC and plug it into the receiver.

It can't get any simpler than that! It's not possible to hook it up wrong. (Yea, I'm going out on a limb here....)

Does the battery pack that came with your Albacore have connector already installed? I think that you will need to create a small wiring harness that will connect the battery to both the BEVR and the speed controller. If you use a switch, it would normally go *before* the harness so that both the BEVR and speed controller are shut off.

I'll try again too.

For the

I'll try again too.

For the APC-3, connect the dive plane servo to the receiver. Then disconnect it, and insert the APC-3 in the middle, between the RX and servo. It only goes one way. Done.

I'm getting the thought that the problem may be wiring the BEVR. If you've never used a separate voltage regulator before, the included instructions are terse (but accurate nonetheless). Let's completely forget switches, IMO they're not needed, but up to you. I can take a pic, but it wouldn't show much as there's lots of electronics in a small space and wiring can't be traced from photo. Anyway] IMO erroneously still call a male connector...doh!, if you're asking for it), or you can cut your "flight pack" harness switch connector off and wire that to the BEVR output. Pretend the BEVR output is the flight battery pack with your harness, that's what it's eliminating. I suspect this is the confusing point. The BEVR strictly supplies power to the RX and servos, like a regular RX battery would. The other stuff is powered from the battery directly. That's why putting a switch in the battery lead completely kills power to everything. The "flight pack" harness switch would only kill power to your RX and servos if you used it...not really good/safe enough by itself.

If the BEVR wiring is in fact the problem, as Skip would say, read the above 3 times. It may be verbose and "circuitous", but is correct as far as it goes.

YES!!! I finally powered on

YES!!! I finally powered on the whole boat, and everything works great!

Thanks for all the help!
