SpartanRC DS760 Gyro Review and Setup Vids

[Angelos]

1.05 - Adds functionality for our own internal use. There is no change or benefit to the user.
1.06 - Fixes a little problem with the 8700G binding on power on during gyro calibration before the ds760 starts sending a control signal to it.

I got mine from the batch that came in to RH the Friday before last and it shipped with 1.05 on it.

OK, thanks, guys. I haven't followed this thread so I didn't know that it had been updated with so many new versions.

I think I'll try to update and see which version it has, - or can you check this in any other ways?

Is the version 0.06 necessary if using a DS8900G or does this only need to be done with the DS8700G?

Thanks,

[skeppley]

I have a new one for sale:

Thought you guys looking in this thread may need one :)

One more video with the 6S setup. http://vids.myspace.com/index.cfm?fuseaction=vids.individual&VideoID=20951393

What tail servo is Alan using in this video with this Spartan Gyro?

And also - what votlage is the BEC running at? 5v?

Many Thanks,

Neil

[MarkWebber]

3400G in that video. Don't know about his BEC particulars.

is there any word on when the pocket pc editor will be out? It would be nice to adjust things at the field and testing it out on the spot without taking a laptop out there.

[sonofcar]

so install the ds760, set it up and it works perfect on the bench. Go to test fly it and works as it should for about 5 seconds and then boom, tail starts spinning around out of control. land it check it on the bench and the gyro is not correcting the servo like it should. Its in hold mode 70 percent gain, servo moves with stick and will stay as it should waiting for stick or heli movement. The pronlem is the gyro will not correct. on the bench i move the heli around and it (rudd sevro) stays and does not move. I read the manual again and reset gyro two times, everything is correct. but it still does it. any ideas would be great i really want this thing to work as it should.

Sounds like you have the gyro reversed..suggest you check Gyro direction again.. cheers Brian

I dont think thats it because the sevro is not correcting in either direction. when you move the heli on the bench you should see movement from your servo which is the gyro correcting. But mine wont move unless its told to by stick. so it doesnt matter what way its set, it not correcting any directon.

[highland flyer]

It still sounds like something is not set correctly still..

Bob has a setup vid at the beginning of this thread that may be worth looking at.

i seen that, an set it according. but no go:confused:

Inspect the gain channel connection, might not be seated in receiver correctly, failing that why not contact Spartan support, they are normally very quick at responding.

[th3tick]

It sounds like you've got the gain channel not connected properly, and it's going at 0 gain. Can you detail your radio setup, receiver, and channel?

jr 9303 gains at 70 gyro led is solid meaning its in holding hold have checked and rechecked set up acording to manual. and again it workes fine on the bench last night and for a couple seconds on first flight. then bam now it's doesnt work no matter what i do. whats the best way to contact spartan.

the exact same thing just happened to me! I recently installed my new AR7000 rx. I have an X9303. I put the gain at 72. First take off I got severe wag and ended up breaking the landing gear.

After the replacing the part I tried again. Before takeoff I confirmed proper gyro response. I lifted to a 1ft over, held it for 2sec, then I tried to turn. The tail started to wag for about 2 sec and it just gave. The heli piroed fast and I crashed.

I did fly this heli before with that gyro and a Futaba Tx/Rx. One day, during a flight, the tail suddenly started to wag heavily for no apparent reason. It is during the rebuild that I changed the TX/RX so I can not say if my new X9303 values are not at fault. I know my gain lead is ok since I was able to program my gyro.

But the fact that you experienced the same thing tells me there must be something else...

Goto the Spartan RC website, and click support.

[mporlier]

I just wrote to the support page quoting both incidents.

[mporlier]

Quick question Sonofcar, did your gyro enter setup mode for no apparent reason prior to flying cuse mine did.

[th3tick]

Strangely enough, I've had the one on my T-Rex 600 go into setup a couple times now too, both at the field.

In fact, I just today re-did the setup of mine because I could hear buzz the last time I was out flying, and sure enough, both endpoints were off today.

My other one hasn't done this, but doesn't have a lot of flights on it yet...

No piros-out-of-control here, however, just lost endpoints.

Ah Ah !!!! We are on to something here....;) lets investigate more!

By the way if it is proven it is a gyro malfunction will Spartan pay for the crash?

[sonofcar]

no it did not go in to set up mode. It just does not correct direction.

[th3tick]

I can imagine it would be pretty catastrophic if it lost sensing direction, or went to the wrong servo type. Neither of those sound like what sonofcar is experiencing, however.

I have an S9254 hooked to both, so they're both the default servo type, and the default direction is correct, so that may have saved me from catastrophe...

[Angelos]

I have never seen a ds760 entering setup mode on power on and I must have power cycled my development gyros thousands of times on both Futaba and Spektrum receivers. If this happened it is most likely the result of a glitchy switch on which the gyro may see as toggling the gain switch and enters setup mode. The time window to enter setup mode only lasts around 4 seconds (during calibration time) and it is not possible for the gyro to enter setup mode in flight. If you experienced such issue please PM me your receiver model and let me know if you are using a regulator or BEC. If some similarities arise I may be able to replicate it. Meanwhile I will produce a firmware update to "mute" the gain signal for the first half second after power on which should mask any power on glitches and should eliminate the possibility of unwillingly entering setup mode.

We have already responded to mporlier's issue in our support system. sonofcar I suggest you also do the same as I would like to go step by step and understand what exactly you see. When you contact us also please let me know if you have a Flash-Link USB cable which may came handy to run some diagnostics. In any case based on the information I see on this thread two issues you guys experienced do not appear related in any way. First indications show that mporlier may have just been running very high gain after changing radios but I will continue the talks with him and check everything in detail.

[th3tick]

How many toggles does it have to see to enter setup? It seems like if you made this higher - say 4-6 full toggles, a bad plug-in is less likely to be mistaken for it.
