Default DS76T Tail Servo Upgrade - Simply The Best !!

I've flown the 130X for years...in fact I got the first one from the LHS the day they arrived...

And within a few weeks I had all the upgrade bling and blam...and the local heli guru built it up for Me

Years later and even though it's discontinued...parts are still readily available and I've discovered the simple solution for the tail servo

So here's the 130X that the local guru used to fly...now a member of My fleet...with a DS76T mounted and displayed in detail

And the entire swap is so simple...I'd guess 30 minutes from teardown to maiden

This particular model got the Lynx servo adapter and a Blue Arrow adapter to get the servo lead to the proper connector...but it's just as easy to solder the old stock servo lead wires to the new servo

Twist the servo rod 90 degrees from stock...so the hook points up...and I used the second hole out from center on the servo arm (open up the hook slightly to accommodate the thicker servo arm)

Mounted using the MicroHeli servo mounts...with a Lynx servo case stiffener

Not bad for someone who was pretty much against the DS76t "upgrade" just a bit over a month ago.

I know I put off switching to the DS76t for quite a while, and probably never would have if I hadn't come up with a spare one by first swapping out the DS76t from my 300x.

Maybe I was just becoming more comfortable with the 130x at the time, but I thought it was crisper and more fun to fly the 130x with the DS76t on it.

I wasn't against it...just did not realize that the DS76T was even a possibility...

I've dumped thousands into 130X upgrades...with few of them giving much of an improvement to flight characteristics

The stock linear servo has it's weaknesses...and the DS35 and DS883 have their issues too

But the DS76T is certainly worth it's cost...~$36

And for that it earns mention...hence this thread

I also assume that the same could be said for the H3060...and perhaps even the KST215

Totally agree. After about 4 years of frustration and spray cans of Deoxit and Air, this was the best upgrade/repair that I have ever done to this great little heli

Jon: Got a source for the stiffeners? I gotta get my hot little hands on some more DS76Ts.

I replaced a DS35 with an old DS76T on one of my 130Xs. That particular heli always had tail wag issues, but not any more. I had tried a couple of DS35s in that bird and some had less wag than others, but it always had some wag, no matter what I did.

Now it flies with the tail locked in like a well oiled rifle bolt, and more tail authority to boot.

No problem...

Just passing along info from previous 130X threads that convinced Me to give the DS76T a try...

Breathed new life into a model that I'd pretty much given up on

Is this the servo with the single board/double board issue?

No...you might be thinking of the DS-35

This is the 450X tail servo I am using

I just noticed that the CF servo stiffener is getting really hard to find...

So here are some options...

The 180CFX uses the same size servo...so any of the aftermarket options for mounting the tail servo "under" the boom as an integrated part of the front boom mount should work just fine...drill out the mounting holes to accept a 1.5mm hex screw

MicroHeli / Lynx / RKH all made such upgrades...and with a bit of work you could possibly remove the plastic stiffener from the stock front boom mount using a dremel grinding wheel and some due diligence

Here's an addendum to get the stock servo rod correctly modified...

The first picture shows the stock servo rod in the correct orientation - hook toward the camera

The second shows how I grip the angled portion so it stays in proper position...then I use another plier to twist the hook 90 degrees clockwise

The third shows the hook facing up - ready for installation

You will also need to open up the hook slightly to get it to go into the thicker servo arm - I use the second servo arm hole

Keep in mind that the rod is stainless steel...not prone to twisting...so look twice and twist once so you don't snap it in two

I just drilled out the servo arm hole slightly.

Shame shame on sloppy servos...

The fix is 2 seconds with a needle nose plier...if you want...bend it back

So I performed the upgrade today to the DS76T tail servo. I installed everything as shown in the forum and when I lifted off I was greeted with a really nasty tail wag. I set the the heli down and reset the gyro gain to factory and it did not help. I bumped the gains for the tail down as low as they can go and while it helped a lot, the tail was still wagging.

This is a second hand DS76T so I can’t speak for how it worked before but I can say that during testing it works fine and seems smooth. FWIW, the 130X I put it in was 100% vibration free beforehand and has zero tail issues.

Thoughts?

I typically use 4-8 clicks reduced gyro gain...

But if itís a used servo it may have an issue - what servo arm hole?

i had it in the 3rd hole going out away from the servo horn screw.

**I also just tested the other DS76T I had which I know works perfectly. Same result. I’m baffled.

I have done all 12 of My 130X's...with a 13th build waiting for servos/3n1...

And none of them have any issues whatsoever

I would reset the gryo gains to defaults...and try 2 clicks at a time either way to see if you can find a sweet spot

Typical is 4-8 clicks lower as indicated above...and try the 2nd hole

I didn't touch the gyro gains (I dont know how) Definitely the second hole on the servo arm.

Setting the Gyro Gain thru the Advanced Gyro Menu is pretty basic...

130X Gyro Programming

Turn on TX - Throttle to 100% - Plug in Batt

Flashing Blue indicates Gyro Program Mode

(move cyclic stick down to switch between gains)

Red solid - Elevator Value at Zero

Green solid - Aileron Value at Zero

Blue solid - Rudder Value at zero

(move cyclic stick left to lower - right to raise)

To set factory defaults mover rudder to right for 5 secs
