SpartanRC DS760 Gyro Review and Setup Vids

[Finless]

Yep this is how the Spartan shows you your gain is too high. It doesnt wag in the hover like others but if you get a wag like that down wind drop your gain until it stops doing that.

Is the DS650 still expected to be only around $30 cheaper? I may just have to skip my next crash and just get the DS760. What features would I be missing with the DS650?

My understanding is you wont be able to set up the advanced stuff as it wont support the USB connection. Everything else should be the same so Angelos told me.

Mpolier. Reference your tail wag.Bob is correct about the Gyro gain BUT the 600 N is very prone to the tail boom clamp moving it needs to be 100% solid.

The Align design is not great as the plate that compresses the boom distorts as you tighten it after a short time (see the horozontal fin will probably be bowed, If you remove the clamp you will also see the boom is polished where the clamp has been moving).

When you try and tighten it further, eventually either you strip the plastic or with the Align metal version the assembly bottoms out without clamping fully due to the plastic plate flexing.

Here is a quick fix.. get a piece of thick carbon 2+mm and make little plate to support/replace the horozontal fin (make sure the bolts/screws are the right length to avoid stripping) being thicker it prevents the plastic plate distorting.

The other fix is to get the Quick Uk fin clamp which clamps by compressing the boom a full 360 degrees, much better design.

We found doing this generally gave an immeadiate 5%-8% gain increase over the standard set up with the Spartan with similiar findings with other Gyros

The best fix is to wrapp a piece of wide clear tape (like packing tape) aroud the boom (one wrap only DONT overlap) and then the clamp will work and NO WAY is it going to slip :)

Bob's right about the ds650. Same performance as the ds760 but you won't be able to tweak the settings with the configuration software. Of course, if you ever find you need to do this, Spartan is going to make an upgrade available for the ds650 which will convert it to the full capabilities of the ds760. You'll even get a new label showing it's now a ds760:wink:

Now tell me, what other sport gyro can match that?:smokin:

And yes, it's going to be about $30 less than the ds760.

[Finless]

Well I havent seen a gyro YET that can match the Spartan ANYWAY.... I mean come on.... Flashing NEW software is a FIRST!
That just plain ROCKS for sure....

Let alone the thing performs great!

I love mine man and THAT you can take to the BANK!

I would "REALLY" like to know if the wires can be shortened?? They are "WAY" too long. Please advise, thanks!

[Angelos]

OICU812,
The length was chosen to be sufficient for a big range of helicopters. It is no problem for the electronics if the cable is shorter but we can not supply the gyro with a shorter cable as a lot more people will then need to use servo extensions which are not very desirable.

Still, I would advice you not to shorten the cable as you may later find that you need it for another model. Since it is a single flat cable it is easy to keep it tidy by doing a few folds back on itself (see attached photo).

I want to buy one now for my 600 but they are all out of stock :bawl

[th3tick]

OK, I just set mine up on my T-Rex 500, and I had one question. If you bind with the rudder stick to the left, doesn't that mean it will failsafe into a pirouette?

John

[Angelos]

It has been discussed many pages back on this thread. The Spektrum radios I have seen so far have failsafe on throttle only and thus it won't piro on failsafe. However the best thing is to do a bench test and confirm it. Make sure the gyro has initialized and running. Use the rudder stock and move the tail blades near zero pitch. Then power off the TX and see if the blades stay put or quickly zip to the limit. In a later firmware I will probably add the ability to bind with very low gain which you may choose to do instead.

-Angelos

[Pinecone]

All Spektrum Rxes, except the AR9000 and BR6000, failsafe to last known position on all but the throttle. On throttle, they go to the bound position.

The AR9000 allows you the choice of that above method of setting the failsafe position on all channels.

BR6000 failsafes to bound position on all channels.

Just posted the video showing the PC Configuration Software.

Thanks Bob. Great video.

Are there any suggested endpoints for the ds 760 to get optimum performance?

I always hear that on a futaba 611 to have to endpoints between 110 to 120. Also, I hear on a 401 to have the endpoint between 80 and 100 (something like that).

[Street Flyer]

anybody?

I only wish someone would get them in stock so I could ask the same question!

The rumors aren't always correct. The endpoints are just absolute limits. When the gyro reaches them it will just stop the servo moving further. They have no effect in the performance. However you should ensure that your servo has sufficient travel.

If you put the ball link too far out you will end up with very little servo travel and very low endpoints. In this configuration you are also loosing torque but gaining speed in repositioning the tail blades.

Similarly if you put the ball link too close you will end up with a lot of servo travel, you gain torque but you loose correction speed.

Between the two, I suggest to keep the end points around 100% (+/-15 if possible) which is a good balance between torque, correction speed. If it is a large heli you may want to put the ball link further in which will result to higher endpoints but will give more torque to move the larger tail blades.

Hi Guys,
my apologies for the stock shortage. Demand is very high and unfortunately our assembler could not get them done before Christmas. I believe they are back at work tomorrow and I will make sure things are moving. I hope that we will be able to get them shipped to the stores in less than 3 weeks. Meanwhile, there should be a few left in our UK dealers and I think all of them post abroad ex VAT.

Cheers,
Angelos

Angelos... I am seeing your gyro all over the place now.... Everyone that I talk to that uses one loves it... Just FYI for you... You got a great gyro here!

Bob / Angelos

Sorry to repeat if this have been covered previously in this long thread......
Anyway, question is whether it is actally needed or beneficial for the function of the gyro to set the tail pitch slider offset to approx 8 degr, if i NEVER intend to fly rate mode. ?
Further, is the metal mounting plate needed on a T-Rex 600E ?. Any experience ? The plate weigh more than the gyro so I would like to remove it......

[Angelos]

The 8deg are needed only for rate mode. However, if you don't set it mechanically and you toggle the gain switch in flight the heli will piro.

Most likely you can do without the plate on all electrics. I know people who use it on the 600E with one soft pad only.

Thanks Angelos.
I always fly ONLY in AVCS mode and cant find any reason to fly rate mode at all.
Look forward to test fly as soon as the bad weather leaving, also to see how the new Futaba BLS251 brushless is working.

I've got it on my 600E with no plate. Works great!:thumbup:
