R/C / FROM 12V BATT to ESC to 6V R/X
« on: September 12, 2020, 10:28:27 am »

HI ALL   NOW  THE SET UP  IM NOW ASKIN ABOUT IS  SOMETHING IVE NEVER USED BEFORE  as ive alway used 40meg  SO PLEASE   EXCSUSE ME  OVER THIS well i think i have a problem on  the R/C as im USEING A NEW 2.4 gig R/C an im now tryin to wire it all up


 NOW my problem is the ESC must supply the power to the R/X an the R/X must not receive no more power than 6v  but as i want to power my motors as i have four motors in my ship i want to use a 12v battery to power the ESC. So will the ESC automaticaly cut down the the power to the R/X to 6V an no more ? as it say in the R/C instruckions that any more power over 6v will damage the R/X SORRY TO HAVE TO ASK THIS STUPID QUESTION BUT I DONT WANT TO CAUSE DAMAGE TO A EXSPENSIVE UNIT
HOPEING SOMEONE CAN HELP ME

If you Esc has a BEC output, and you use it, you will be safe.

Perhaps you had better tell us what Esc you will be using (preferably with a link).

PS The radio frequency makes no difference to this as 2.4ghz receivers basically require the same voltage as did 27, 35 and 40 Meg receivers.

There are 2 types of esc, one with a Battery Elimination Circuit, BEC and, one that doesnt have a BEC and is called an Opto esc. These may also be known by other names.
An esc with a BEC will normally step down your motor power battery to around 4.8v. More expensive ones give you the option of selecting around 4.8v upto around 8v.
If your esc is an Opto, you must power the Rx by a separate battery supply. Again, this is normally around 4.8v although more modern and expensive Rx's can run off upto 8v. This separate battery power must not be plugged into the BEC esc.
Your radio frequency has no impact on esc, only the voltage the Rx can handle is something that may need to be considered.

This is an opto esc like I mentioned. You need a separate battery to run your Rx. This pack must not be connected to the esc.

There are two different ESC listed here.

The FS-AQP128 has a BEC 5v 1A  (there will be separate connectors for the motor and BEC output circuits)

The FS-AQP280 does not have a BEC so you cannot power receivers and servos from the ESC. (the only output connectors will be for the motor)

Which ESC do you have?

A 280 amp esc is certainly powerful. Are you racing fast electric boats?

NO im not raceing fast eletric but a ship with 4 motors in a warship an its a fair size
HI [size=78%]justboatonic[/size][size=78%]  IF you look at the specifatcations i think it says it has a BEC fitted in an not an opto ? an if thats the case i must not use a seperate batt as thats what its says in the R/C INSTRUCTIONS  DUE I WILL CAUSE DAMAGE TO THE R/X [/size] AN IHAVE POSTED WHICH ESC I HAVE GUYS

Hi. If you have the Fusion Aquapower 280 as per the photo, the product description on the net states this is an Opto esc and you need a separate battery supply.

https://howesmodels.co.uk/product/fusion-aquapower-water-cooled-280a-brushed-marine-esc-electric-speed-controller-boat/

or a 12v to 5v converter something like this:
https://www.ebay.co.uk/itm/DC-DC-Converter-Regulator-12V-Stepdown-to-5V-3A-15W-Car-Power-Supply-Module-UK/142407861263?hash=item21282b840f:g:JXQAAOSw5cNYcSC7

Note that I am not recommending this example as I have never used one but it shows the sort of thing that you need. You connect it direct to the battery supply (via a 3A fuse) and the 5v output to the receiver.

PS the spec on the box tells you that there is no BEC for your Esc.

I rather suspect that frogman3, along with most others forum members, doesn't know the difference between an Opto Esc and any other.

HI Tug fantic  you are right i dont know the difference between them as ive always used eletronize ESC MICRORPESSER on  40 meg   but now that chap has retired ive got to look for a DIFFERENT ESC that will be powerfull enough to power 4 motors in my new ship an it must have a BEC an i will not use this FUSION ESC that i have got so any idea's of a new powerfull ESC with a BEC fitted an  guys an thank you both for your help on this matter

Yes, it is a good point and the beauty of this forum where we can share knowledge. That's why I thought best to give a brief explanation of the difference in my earlier post. Sometimes you also have to look at all the specs to find out if an esc is an Opto. The ad I linked only states the 280 is an opto esc at the very bottom so could easily be missed.


@Frogman, why not use this esc, it appears to have the power you need? All you have to do is plug a separate battery into your Rx which will probably only cost a tenner while a new comparable BEC esc would cost a lot more.

Again we need more information.

Please tell us a little about the model that you are powering and the motors / propellers that you intend to use. Type eg battleship or high speed Motor Torpedo Boat etc, then size of model, then motors then propellers (make, model, no of blades, size) . You have previously stated 12v.

The fact that you are using 4 motors is largely irrelevant as what we need to do is estimate how much power in total they will use.

If that is the 1913 HMS Tiger battlecruiser your model must be around 3m long and, if your underwater shape is scale, will probably weigh 50kg+ loaded WOW!!

HI NO its not the 1913 tiger but the tiger that was converted into a helicopter carrier in the 1960's she is also a  half battle cruiser an half helecopter carrier in 1/72 scale so yes she is big nr 8ft long
an here is the requested info on the motor's all 4 the same an the 5 bladed brass props in the link below

I honestly think your best solution is to still use this esc and buy a separate Rx battery pack. You will have plenty of space in that model for the additional battery which will be a couple of inches long and an inch tall tops.
Even if you bought the AQ128 with a BEC, you'll be spending another 30 possibly plus P&P.
The only thing that concerns me is these esc's appear cheap compared to their amps ratings!

I don't know how to decode Johnson motor numbers but working on the basis of the propeller your existing esc is likely to be able to handle vastly more power than you will be using. That is a good place to be.

Justboatonic is making what I think to be a very good point. Why not try your existing esc before you give up on it. It should be perfectly OK.

As long as you don't both have a BEC AND a separate battery (which you won't as you don't have a BEC) connected to the receiver I cannot see how there can possibly be a problem.

I wait to see if anyone else can see a problem.

What is the radio?
