Default Micro receiver help, please.

Ok all, I've been out of the loop for quite some time and have done quite a bit of research and still have not found a solid conclusion for my questions.
I am building a desktop crawler and am looking to use this receiver for the build.
It is compatible with Futaba S-FHSS protocols and claims to pair well with the futaba 3pv. My concern is how I am going to get power to the receiver, and have convenience of an on/off switch.
I also plan to use a micro servo pcb as a speed controller for this ride, so power would have to be supplied from the receiver.

Please bare with me and be kind, I'm not very savvy when it comes to electronics.

Q-1: Can a 4 channel receiver be controlled by a 3 channel radio?

Q-2: Can I use the 4th port to plug my battery to?

Q-3: Can I have an on/off switch on that port?

I'm sure this is a simple task, I just want to go about it the right way and not burn anything up.

Thanks for the help in advance.

I think you will power up with the speed control /esc...
Plugs into port one or two..
q;1 Yes
q;2 No I'm pretty sure you Don't want to plug the battery into it.
You should have a speed control/esc to power it up and plug into the port 1/2
q;3 I'm not sure on the power switch.

Port 1 and port 2 are for steering and throttle crontrols.
3 and 4 are used for lights or other things...like an extra servo.
Not much help but maybe a little.
Luck in your journeys.

If you post a model number or something we could probably get more info for you.

Your battery and switch questions have to do with your esc.
If your esc has a bec in it, you'll hook battery to esc, it should give you the power switching, and feed power into the port on rx you connected to.
If your esc does NOT have a bec, or not even running an esc, then you'd need to feed power into one of the channels, preferably with with a switch on the + leg. Maybe a stand alone regulated bec if you need stable and have room.

What's the project? I've been trying to plan out what i Want for a TTTT build

If you're using a small enough battery, you can plug it right into the receiver. Like a 4-cell receiver pack would be fine. Running 2 or 3 lipo cells would blow it right up.

You'd be better off with a small ESC if space and budget allow.

Ok, so this is the project that this will be for. The receiver can be found on amazon( DasMikro DSK-117). The battery is a 400mAh single cell lipo. I had planned to use a modified servo board for the esc(this has worked just fine for past micro builds) so a bec would not be included in this project. I am running out of space quickly as it is.

I know the receiver has to get power from one of the ports, but I'm not sure if it is safe to directly supply the power to the receiver or to somehow modify the servo board(esc) to have a battery plug and on/off switch.

The picture depicts what I had in mind, just don't know if it will work.


Thanks guys for all of your input.

The only problem I can think of is voltage drop under load, but with a truck that small, how much load is there going to be? Not a whole lot. Assuming the receiver can operate at 3.7V and less, it should work fine.

By the way, that's an amazing build
