SpartanRC DS760 Gyro Review and Setup Vids

[Angelos]

Hi Bob, For the 8 deg pitch on the tail rotor why not use a micro heli pitch gauge and use the tail boom as a reference?

Not all helicopters hover at 8deg pitch thus there is no point in trying to get it perfectly accurate. Anywhere near 8deg is a good starting point and if in doubt set it a little less rather than more.

Also, in AVCS (heading hold) mode, it does not matter what the neutral tail pitch is. In Normal mode you need to get the tail pitch right in order to compensate the main rotor torque. In the ds760 I have done a little trick that simplifies things. I mix a very small amount of heading hold into the normal mode. This give the ds760 the capability to correct for small errors in getting the tail pitch right.

Which explains why I had such an easy time of setting it up on my Trex600. Easy being that I didn't have to do a thing and it was spot on.:thumbup:

Same here and MAN!!!! This gyro had NO DRIFT AT ALL.....

When I can ring this out I will let you know but I gotta say so far REALLY this thing rocked!:thumbup:

i have a question . how do you mix a little of heading hold and rate together i have never heard of that before but it sounds interesting

[Angelos]

matrix1171, have you noticed that I am the designer of this gyro? Being in this position I can do things that are not normally possible to the end user. If your question was technical, inside the gyro everything is represented as numbers. To mix two signals you scale them with the right percentages and then add them.

[matrix1171]

yes, i did notice. i had no idea that you doing it in the gyro itself, thought it was a radio mix. that's why i asked, it's pretty cool none the less

[emag remrofni]

Man I thought this was an El Cheapo gyro until finless endorsed it. That means I gotta have it now:drool:

[MarkWebber]

Nope, Spartan RC doesn't do "el cheapo". Those of us using their other products know that these guys won't release a product until it's top notch.

[Pinecone]

And the price sure isn't el cheapo.

I would love to try one, but th price is holding me back, when I can buy goood used 401s for $90 and a new 2100T for $105.

[Angelos]

Pinecone,
It really depends on what you need. The ds760 does not compare with either of the two gyros that you mentioned. The 2100T in particular is not suitable for nitro helis as the tiny wires aren't meant to take the current that a normal size digital servo requires.

Even on a small heli like a Trex450 the ds760 seriously leaves the competition way behind. Here is a little video sent to me by one of our sponsored pilots. Unfortunately it was shot on a mobile phone but I will do a better one when the opportunity arises. http://www.youtube.com/watch?v=Lr4pl4r0lf0

In 1-2 weeks time we will be releasing the Spartan ds650 which will be a more affordable option at around USD 30 less than the ds760. When launched, the ds650 will have the same electronics, piro consistency and holding capability as the ds760 has today. However, the firmware of the two gyros will evolve separately and updates made to the ds760 will not automatically become available to the ds650 too.

The ds650 will support firmware updates via USB but we dropped all other connectivity features as well as support for the Futaba S9251/6 servos. So basically you get a simplified gyro like the GY401 but with much better performance and ability to set left and right endpoints individually.

This makes the ds760 our Pro fully featured gyro and the ds650 will be the more affordable Sports version. The best part of all... when you are ready for the extra stuff for a small fee you can get the upgrade firmware and convert the ds650 to ds760! We'll even send you a red ds760 label to replace the yellow one of the ds650.

Hi angelos

Perfect to have the posibility to talk to the people developing the products!

Is it possible to do a flybarless setup with your gyros? Like CSM 720 + CycLock.

Need to know, because im planing to puchase a couple gyros for that application.

best regards Anders

show me an el-cheapo that flies like this.

Great flight Ade, I think a DS760 will be going on my Xmas wishlist...

It is possible and will certainly do it. However, CSM have worked out some different tuning parameters for their 720 gyro which are more suitable for flybarless. I did not have to do this yet but will get done soon. However, I am not a big fan of this solution with multiple boxes and untidy wiring. I much prefer a single box fully integrated system.

And that is your next product?

[Pinecone]

Funny when a 401 is considered an El Cheapo. :)

Never said the gyro wasn't good, it is just that for those of us flying smaller helis, the price is a barrier.

[BigVanVader]

I had the chance to fly HC's Phazor 600 with the Spartan DS760 gyro this last weekend....it holds as good as anything I have flown and thats pretty much all of them:YeaBaby:
You have a winner on your hands Angelos:thumbup:

[mporlier]

Hi Bob,

I know you are super busy. Hope this week-end birthday party went well. When are you coming up with the rest of the DS760 setup?

Marc

[Finless]

The rest? You mean the PC software setup?

I am waiting for Angelos to release the next version before shooting that video. He said it shouldn't be too long.

Bob

[scottc]

any update as to when the Spartan ds650 is coming out.

[Angelos]

The ds650 labels just arrived. Should have some ready in 1-2 weeks. PM me if you want to reserve one. There are plenty of ds760's in stock.

So how does it fly compared to 611 and 6100 systems? Did you get to fly it properly yet Bob?
