Default 3PK HRS rx runs on 6V vs. TC3 runs on 7.2V?

I just got a used 3PK tx with the HRS rx.

I didn't realize this, but the owner's manual says the HRS rx must be run on 6V batteries.

Obviously, the battery packs used in my TC3 are 7.2V.

Do people running the HRS rx use some kind of resistor between the battery pack/ESC and the rx? If so, is there a plug-and-play adaptor that someone sells or would I have to make it myself?

Or do I need to use a separate 6V battery just for the rx?

Thanks,

Bill

Your receiver takes the voltage from the ESC and the ESC output voltage may very depending on model (I'm pretty sure they are all 5volts). You can obtain a near 6-volt input by using a 5-cell receiver pack).

Look here:

http://www.futabarc.com/manuals/3pk-manual.pdf

On page 7, in the 4th bullet under "RECEIVER: R203HF or R113iP," it says:

"HRS receivers require 6.0V batteries and digital servos, including for throttle."

All speed control has BEC which reduces the voltage from 7.2v to 6v for the receiver(your motor still gets 7.2v). You don't need a receiver pack to power your HRS. The manual say so because there are situations you need serperate receiver pack, e.g. gas car, 1/12 on 4cells(4.8v).

Default No problem

I run all my 3pk receivers off my ESC with no problems
This includes HRS, PCM and XXXL from Novak.

No voltage problems, just readjust the TX mode to match
the receiver signal

Make sure you run digital servos with HRS (look it up)
receivers or you will fry the analog servos

Cool

Most Receivers put out 5 volts but, LRP's Quantum 2 puts out 5.8 volts.

The only servos that I've found to accept 7.2 volts are used as Sail winches and they are connected directly to the the battery pack.

Don't worry about the receiver receiving more than 6 volts, it won't happen with most of the ESC's on the market.

Grammar.
The whole "txt speak" thing is so anoying for anybody trying to make sense of peoples posts though. It reads awfully and how hard can it be to press those extra two keys on the keyboard to make a proper word. I can understand why it is used on a phone but on a computer with a proper keyboard i see no need. Please try full words next time you post. Thanks.

Im not having a go at you here, just people who type like this in general.
