My Trex 600 Flybarless using SK360
I have just converted my TREX 600N to flybarless, so far around 16 flights and it flies really good.

No extra conversion kit is required, I've just using the existing mixing arms and a fixing screw.

Casey - Is your SK360 mounted on a plane 90 degrees to the main shaft C/L? Maybe it's just the camera angle, but it looks a bit off the recommended mark.Cheers - Boyd

Hi Hoverup,
Yes,it is 90 degree to the main shaft. I have turned the front mount up side down.

Hi Flyawayed,
The set up is not so difficult, I started from the basic 3D set up that came with the package.

Attached spreadsheet is part of the setting that I am using. If you want, I can send you my setup file.

Hi Caseyho04

I am converting the Trex 500 head to flybarless. Same principle as the 600.

So are you still happy with your head conversion?

The reason is I ask is that your setup is a little different than the others I have seen, since you use the unmodified blade holders and all original parts.

How long rod did you use from mixer to bladeholder. Is it original Align rods?

Did you use a M3 (M3 x 3mm) set screw (the one you use for the lock collar on the main shaft)? Did you just drill a 3mm hole in the washout base and fastened it to the main shaft?

Thanks for all answers :-)

Perfeet, do you have any photo? How does it different from others? I am working on measuring the 450 500 and 600 center hub to make some low cost flybarless conversion kit. Only that project is on hold since the factory is moving, so I still have a chance to modify my design.

Hi Morris

I am planning on using the same setup for making the head flybarless(Trex 600) as Caseyho04, on my Trex 500. You can see his pictures in the beginning of the post.

It is practically identical to the instructions for converting a Trex 450 on Skookum Robotics: http://www.skookumrobotics.com/down...0_for_SK360.zip

I will convert it next week, when my Skookum SK360 (hopefully, if the postal service is nice) will arrive.

One last weekend with a flybar (if nothing is wrong with the new setup)

I will post pictures of setup and how the flight was after that.

I plan on buying the Mikado conversion set when that is back in stock...

quick question about the sk360, converting my 500 and got everything working and adjusting properly, my only question is when in setup mode and I move cylcic with tx the cyclic servos move fast like normal, but when I am in flight mode and I initialize everything up and move cyclic all movements in right way except it seems really slow movement not near as fast as when i move them in setup mode is this normal.

Yes, this is normal. In setup mode the sk360 is directly translating stick position into swash position, to make mechanical and mxing setup easier. In flight mode it is instead using a control algorithm that can be counter-intuitive at first, a bit like how a heading-hold tail gyro behaves.

Just did my first 11 flight with the newly installed sk360 and vstabi 500 head. Holy crap what a machine, it flew awesome right out of the box, had to crank my control rates to 285, to get the rates I wanted but other than that it was sweet, question, what do other people that are doing 3d have their advanced options set at. like control rates and bell hiller rates, and also hiller decay

Is the SK360 available at any stores in the US or do you have to order directly from the manufacturer?... BTS

Ordering from Canada is like rolling the dice. Sometimes a package gets caught up in customs drug inspection for many weeks. I have had some fast and some very very long shipping times myself.... BTS

By popular demand SK 360 is now available in the USA. I got mine from Canada and had no problems. Also set my head up like Caseyho04 suggested and it works fine. Originaly I tried the direct linkage set up but had to turn everything down to the point that I was getting no resolution. I used the Mikado swashplate driver. Just so I did not have to drill and tap the original washout unit. It is on sale at A Main Hobbies $30.00. Here is link to us distributor for SK 360.
