Most servo winches require less voltage 6v - 7.4v
to net the same amount or more torque.
Tho this does not necessarily equate to more line speed.
As that will likely be dependent of an particular servo's actual speed,
voltage demand and gear ratio.
IMO servo winches are not scale looking whatsoever.
Many choose a servo winch more for performance...
then how it will realistically looks mounted on a chassis.
I instead prefer the scale look, over performance solely.
My RC4WD Warn winch can handle 12.60 v without issue
and while I initially utilized the RC4WD wireless controller.
I have since changed to the Heyok wireless controller.
The Heyok wireless controller much improves the RC4WD Warn winch's
performance and strength.
And IMO is a must have if running a scale looking winch.
Changing to the Heyok wireless has increased power
as well as line hold/strength.
Prior the RC4WD line/spool would creep out due to the chassis weight.
This occurance has been nearly diminished with the use
of the Heyok wireless controller.
The Heyok line hold is electronic
and is incorporated on their wireless, as well their "hard wired" TX winch controllers.
Because they are designed to utilize 12.60 volts.
the RC4WD Warn winch is faster and stronger as far as it's holding power.
Granted the rig weight will play a vital role
on how fast the spool/line may unspool due to rig weight.
But mine holds purdy well...
and my over-all chassis weight probably weighs in near 10lbs +
It does creep out ever so slightly...
but is likely due to my excessive weight
and if weighing less... wouldn't probably creep at all.
The advantage to using a servo winch
is...
1. They're inexpensive to purchase/alter.
2. Their reduction gearing is generally lower.
3. They generally require less voltage to produce the same torque.
4. They are generally slower but that depends on the servo's speed and voltage requirements.
5. Some folk are more interested in performance/durability then scale looks.
6. But that's not me.
The RC4WD Warn winch can use more voltage then some of the lesser scale winches sold.
ie: the 3racing winch is down on voltage/performance
when compared to the RC4WD Warn winch ( 12.v + )
I run my Heyok wireless controller directly off my primary 3s LiPo.
And the RC4WD Warn winch runs strongest when fed 11.1v - 12.60v.
To each their own... But I prefer the scale look.
As I don't utilize my winch on a daily basis.
But in reality... don't use my 1:1 winch daily neither.
Regardless of which is utilized...
I would not run the winch's voltage needs thru the RX.
And instead would recommend using a voltage by-pass
feeding only the signal thru the RX
and the voltage demand would be fed directly to the winch
from an independent power source.
Thing to be concerned about is how many amps
the winch may draw when stalled, during a heavy pull (load)
Most RX will not appreciate excessive voltage run thu', nor a high amp draw.
