Futaba vs. JR

I remember a few years back when there used to these terrible Futaba vs. JR
radio wars on this newsgroup (esp. the Fut 8UHP vs. the JR 8103). But, I
haven't seen one in a while. Now that Futaba seems to have left their old
8U behind and have moved onto the Fut 9CHP, I have a few questions.

What are the benefits between a JR8103 vs. a Fut 9CHP?
Which servos should I get (I'd like to get a kit instead of buying
everything separately)?

I will be getting the Futaba GY401 w/ servo and am thinking of getting the
GV1 as well. Does this make any difference on whether I get a JR or a
Futaba?

I remember looking at the manuals pretty closely a few years back and
noticing that the JR manaul seemed better written and easier to understand.
The JR also seemed easier to set up. Does this still hold true?

So you thought you'd start one? :-)))

There's still a war raging, but the ease of programmability of the Futaba 9C
has made the outcome a little less obvious. It's supposed to be a world away
from the older 8 chan Futaba, but I never found the 8 that difficult to work
with. (I'm currently playing hard with a 9C and it's not as friendly as I
was lead to believe, but it's ot TOO bad).

I think the switch assigning ability is great with the Futaba and it's a
pity it's not a feature of the 3810/8103/3108/1128 overture, but the JR has
a little more functionality especially in the ECCPM area, so it's still a
case of which one does what you want and which one FEELS better. The sticks
on the new Futaba's are better than they were though, so the feel difference
has also "shrunk".

Yep. The 9C has it's own GV-1 menu and of course the 401 being a Futaba
piece of equipment is also better supported, but they both work very well
with the 3810 too.

In my opinion, the JR radio's ARE easier to work with (set up) but it
doesn't really make any difference in the long run to the WONER of the
radio. You learn how to program the radio you own and that's it. It only
really makes a difference when lots of different radio's pass through your
workshop day in day out and you've got to remember how each one does it's
thing.

It's still a "Ford" v "Chevy" thing though.

Re: Futaba vs. JR

Is that right Beav?
If he uses a GY401 w/servo, I'm guessing the w/servo will be a digital 9253
perhaps?

I've always believed that using a Futaba digital servo with anything other than
a Futaba receiver is likely to cause damage to the receiver.

I've never tried it, so its a doubt rather than cold hard fact :-)

I hope not, I fly JR 3810, but one of my Milly's is kitted out with Futaba

I've got 2 heli's here with the same set up H:. Never had a problem with
them either, and for years, my servo of choice was the Futaba "9" series
(9201, 9202, 9204) but lately I've been using JR 8213's and 27 and 8700's on
both JR receivers AND Futaba receivers. Again, no probs.

I can't imagine why we should (so I don't, I just nail 'em in anf fly 'em

What, that the Futaba ancillairies are better supported within the 9C than
in the 3810? Well yes it is, but that's not to say they're NOT supported in
the 3810, they're just not "specified" as ancillaries.

Within the GV and the 401's respective instruction booklets, you get an
almost step by step guide on how to obtain the best performance from them
along with channel selection, switch selection and the all important (to
some) numbers needed, and everything is spoken about in terms of their use
with the FUTABA radio, not the JR (for obvious reasons). there's no need to
substitute/translate anything from one manufacturer to the other, so it's
more a "plug and play" than a "plug and fart about for a few hours". That's
alqays assuming you can make head or tail out of any of the manuals :-)

Usually yes.

Well I can tell you from personal experience that it's bollocks. There ARE
some servo's which aren't useable in other applications (I'm thinking of the
new JR servo specific to the 6000 gyro), so you couldn't connect one of them
to a normal output on a Rx without hitting some problem, but even that servo
will work with a Futaba Rx providing it's connected to a JR 6000 gyro.
There's a lot of "CYA" going on these days from the manufacturers because of
the "sue crazy" way things have gone.

I've used just about every type of servo in both types of radio and never
seen any problems.

A little doubt never hurt:-)

Re: Futaba vs. JR

Thanks guys, you learn somethin new every day...

I'm just about to have my first digital experience, so after changing a
perfickly good JR receiver from the intended model to a Futaba receiver ripped
from the heart of a perfickly good other model, I now find out it was a
completely pointless exercise....

Gyros aren't arsed about whether the servo is Fut or JR, so I can't see the
receiver being... unless Futaba do a "detect & destroy" of any connected JR
gear not likely though

Servos are interchangeable between Futaba and JR equipment. I've known folks
that fly Futaba transmitters and receivers but refuse to use anything but JR
servos and have not problems. Personally, I prefer not to cross brands but
that's just me.

You shouldn't have any problems plugging JR into Futaba or the other way
around. The only issue you'll have plugging Futaba "J" series into JR
receivers it filing the little key off the Futaba connector so that it will fit
the JR recepticle. JR's wiring colors are a little different from Futaba's but
it's not a big deal. Just make sure the lightest color wires are oriented in
the same direction and you'll have no problems.

Good luck & Fly Safe,

But maybe you've saved some other poor modeler from experiencing the same

Re: Futaba vs. JR

In the futaba manual for the 601 gyro they say to use only servo 9251
,which is supposedly made for this gyro......
the JR 8700g tail can only be used on a jr PCM rec ,thats why they added the
stickers to the front of the boxes .......

Well how does that work then? It's the Gyro which operates the tail servo,
not the receiver.

Re: Futaba vs. JR

It doesn't surprise me that Futaba and JR both would state that you can only
use "their" servos with "their" gyros. Read the literature that comes with any
of their radio systems and they always state that you should "only" use their
equipment with those radio systems.

I know that I've seen "many" folks through the years flying with Futaba servos
plugged into JR "receivers" and vice versa with no problems. That includes the
new digitals servos. I also know that I've seen
different servos plugged into the lower level Futaba gyros (502, 401) without
any problems. I could be wrong but I don't see why a servo other than the 9251
wouldn't work on the 601 although I imagine that there could be a loss of
accuracy if the replacement servo isn't up to the 9251 servos performance
specs. Same goes for the JR gyro systems although again, in this instance, I
could be wrong.

Anyone out there with actual experience with trying different servos on these
top line gyros?

Didn't mean to mislead anyone on this one. My experience suggests that it
shouldn't be a problem although the equipment is changing through the years so
who knows.

FWIW,
Fly Safe,
Steve R.

I've got a couple of 401 gyros that came with the 9253 servo. Both of these
servos started getting "glitchy" after three or four months of use. I've met
others that have had similar problems and I've bet others that have had no
problems at all with the 9253. I'm currently running 9252 digital servos on my
401's and have had them for about a year now and they're both still going
strong.

The 9C manual is much better than the 8U was. Also the 9C is easier
to set up than the 8U. I don't know anything about the JR though.
