JR servos-
 

Hi Guys,
Can anyone tell me the difference between:
DS8425 and DS8411

They seem tobe the same servo??

Ants,
The only difference I see is that the JR radio website does not have any listing for a DS 8425 servo. Are you sure that is the correct number??

Some JR servos have different numbers according to the region. The specs of the 8425 look similar to the 8411 so they are probably the same servo with different numbers. In fact on the Intairco website they advertise it as the 8411/8425.

I personally find it a bit confusing and wish they would keep the numbers the same throughout the world. I am sure they must have some reason for doing it.

Hi Guys,

I am using the 8425's in a jet at the moment in Australia and yes they are the same servo as the 8411.

I do not know why they have different numbers but it seems to be a local (ANZ - Australia and New Zealand) thing.
This is the same story for the 9401 mid size servo which is the same as a 9411 everywhere else!

Perhaps it is the local importers way of identifying servos and confusing people.
They have succeeded on both counts!

I was supplied with a pair from inwood models in the UK.

They leaflet that came with them told me they were the same servo as the 8411, but were suitable for use on 6V rather than 4.8v. (Or if were being pedantic, i can check if it said 5 cell nicds rather than 4 cell nicds) It even gave torque figures on 4.8v versus 6V.

I can certainly check if i still have the box what they meant.

Thanks for you help guys!
I think Dale maybe on to it-
Looks like they really are the same servo- ???

RE: JR servos-
 

This is another JR 'oddity'!

The 8411 is also able to run on 6v but the UK importer apparantly knows better than JR. Most of the official UK JR servos I have bought have a leaflet stuck to the outside of the box (i.e. not put there by JR) restricting the voltage. I guess the reason the 8425 is not restricted is simply that it is not a servo produced for the UK market (and I'm guessing possibly not supplied by Macgregor).

All,

I think I am right in saying that JR servos run 6volts ok but this must be regulated and not an unregulated 5cell pack as this can exceed 7.5 volts fairly easily off the top of a charge.
