Anyone able to post a few pictures of a DS76T tail servo mounted on the 130X?

1) What side of the frame?
2) Servo rod distance/arm hole used?

I have a completed assembly ready to install and another on the way

The Servo is mounted on the left side when looking at the heli from the rear.
I used the second hole on the servo arm and at the servo mid point it lines up really well along the tail shaft. I just bent the standard servo tail rod end 90 degrees. The servo position is nicely forward and can still be moved forward/backwards to get your tail slider in the correct position.

I am waiting for the picture I took to get into the cloud and its not there yet???. I will try to post it later.

One of mine has a DS76T. Remind me to look and see how it is mounted.

After several years I took my v120d02s back. I realized that there are no more walkera tail servants. today I have a lot of confusion. I searched a lot but couldn't find a suitable, fast servo for my v120d02s. so the question is: which queue servant to buy today?

Walkera WK03-4 German dealer (in stock): https://www.fun-and-media.de/epages/...-V120D02S-Z-31

Tail and cyclic servos are "sold out" on so many shop sites.

I have been trying to get the V120D02s spektrumized with a Tarot ZYX(-s) for a longer time (project has been on hold for years after it was not initially working).


I will be trying my luck with the BlueArrow D05010MG (my version has a normal Graupner JR plug).
There is another one: BlueArrow D03018MG (didn't receive it in time...was not in stock after I bought it).

There is another cool servo: Lynx h0988UHS-i (760Ás).

You need a specific FBL which gyro supports the 760Ás setting, e.g ÁSpirit, ÁBrain.
But I have no idea how to deal with the servo arm, ball link, push rod diameter, etc.

If I could, I would just plug into my old Spektrum DS76T; it definitely was working on my 4503D.
But same problem: Servo arm, ball link size, push rod diameter, etc.

Save money. I have already tried d05010mg and D03013. Both are not fast enough for the tail

Ok. If I buy eflite ds76t. I would like to mount this servo in the tail of the walkera V120d02s. But I wonder if it will work at 3.7v?

You're falling behind Kev...

I've got 11 130X's...2 of them are recent new build/rebuilds

And every one has the DS76T w/CF stiffener

I was wondering why everywhere I read that the only alternative for the v120d02s today was this servo.

I've never had the v120 heli...how big is it?

But if it's only a 1S (3.7v) model...the DS76T will most likely be way too big for it

Have you tired the DS35? Same 4.8v rating but on a heli that small it just might be an option

The ds35 has had a lot of complaints lately. The first generation was ok, but the second generation was a failure from what we read

I agree...in terms of the 130X the DS35 is not a great option unless you can find a v1...

But if the v120 is smaller you might get away with it

Is it flying? How valuable is it to you?

Shelf Queen or garbage?

Might be worth a try...if there are few options you can rule them out quickly

However now I ordered it. I have no choice but to try. I will let you know.

JonJet - note that the BEC output on the 130x is also around 3.7V. The DS76t seems to work OK with that, unlike many other 5V servos people have tried to use.

Fortunately, the V120d02s control unit has a switching voltage booster that increases up to 5v and then a 3.3v stabilizer for the microchip. But all servo draw directly from the 1S lipo.

I guess a possible issue with the V120d02s is how well the DS76t works as the battery drains. I'd probably be wary about trying punch-outs towards the end of a flight. Ending a flight earlier than usual to ensure there's margin on the cell voltage might be a good idea.

Yes. As soon as the DS76T arrives, I will do several tests. First as you advised and then slowly I will see what happens. Fortunately the v120d02s also has a cut off that never allows the lipo battery to fall below 3.3v. In fact it gradually removes current from the brushless. I hope this minimum 3.3v is still enough for the ds76t.
