SK360 Electronic Flybar setup and review

There is a 4th channel on the unit that Skookum said could possibly be used as an input for something like that in the future. But as Finless said, currently you cannot.

In the meantime, you could have 2 different cyclic rates by using dual rates and expo...

How is the new firmware working finless?

[Finless]

Honestly I am sooooo busy right now I havent messed with it yet AND Kevin (fireup) is doing a redesign of his Trex500 head parts for flybarless. Kevin is holding me hostage and until I get those I wont be able to test further. Even then it will be 1-2 weeks before I get the time....... Plus I am going to the Bakersfield funfly this weekend...

Too much stuff and too much to do! But trust me I will continue testing VERY SOON!

Anyone have a link on where to buy this baby? I can seem to find it.

Again, my co-worker and friend has been testing this since day one. He said that there is a LOT of setup involved, but once you understand it, it is easy.

I've personally never seen his fly-bar-less setup fly, but hope to soon! <hint, hint>

Yeah, yeah, I've kept it away from you so you won't feel obligated to open your wallet and buy one.

Actually, I wouldn't say there's lot of setup, but being an early adopter means that you have to do the extra work necessary to clear a path for everyone else. That, and the lack of flybarless head options also adds to the curve.

Also, going through this process has given me a much better understanding of the theroy of how a heli flys vs. just being a mechanic and a part-time pilot.

Personally, I think the biggest challenge people will face in the future is keeping tabs on vibes. Yaw gyros are so forgiving that we're almost spoiled. I'm grounded right now because of a couple real notchy tail bearings that drove the SK360 crazy. I seriously doubt the same vibes would cause any problems with my LT2100 or GY401 tail gyros. With the addition of an aileron/elevator gyro, problems will present themselves earlier. Since a problem is still a problem, that just means things will need to be addressed earlier in the failure progression. In other words, you'll just have to be more in haaarrrmmoonnyy with your biiirrrrrdddd... Bahahahahaha.

You are a ball of laughs! I personally hope that companies that produce these types of products for Helis will REFINE their designs based on feedback that you, Bob and others have provided, so that by the time that I get around to "going fly-bar-less", it will be a LOT more tolerant of these kinds of issues.

Looking forward to flying with you again!

P.S.

I'm SURE that HH gyros went through this phase as well when they were first introduced.

Has anyone tested this product on the T600E?

Thanks

Coming up! I am finally seeing the light at the end of the tunnel on the 2 90's I have built! So expect more info coming soon!

Hi..

Yes. I have it on my 8s Trex600E. It works very good.I do have some degree of kick rolls when i have my roll rate above 300%. I also had it on my trex600N, and roll rate had to be a lot less with low headspeed around 1700rpm to avoid those kick rolls. Im having a new SK360 on the way with the new processor update. This should kill those roll kick´s and i will try again on my nitro..

Many thanks to Art, for a great support..

Cheers James

My sk360 on a t-rex600E with rotorworkz cf frame, jr 770g gyro and jr 9900+9717 servos had its maiden hover in the garden today. It seems to work well. The wind was gusty and the hover did not feel particularly stable.

The rotor head is a modified stock head, using the directions from trextuning.com.

The swash setting numbers are about + or - 30.
The phase setting is -7 degrees.

At the end of a 2 meter "auto", it almost tilted to the right. That must be investigated.

I need to do more than hover to say more.
Tomorrow, I will try some sport flying at the club.

Does the sk360 contain any accelerometers?
An accelerometer might prevent the heli from jumping in gusty wind?

Thank you Bob, for the many helpful videos.

I'm wondering the same thing. It helps keep from pitching up or down in FFF.

No flybar + SK360 = No FFF pitch up.

Yet another reason to burn you flybar...

Just ordered a SK360 for my T-Rex 500 should have it in about a week.
Looking forward to seeing more of Bob's and every one's set ups mechanicly and program paremeters will be watching this thread for sure.
