Flybarless Rotor Head Systems > Hirobo Freya with flybarless V-Stabi (VBar)

I have just ordered a Mikado V-Stabi for my TREX 600 and my Freya. There is a lot of information about turning the TREX into a flybarless system. Has anybody tried to convert the FREYA Rotorhead into flybarless?
Pictures would be nice. I will put mine down here as soon as I have the solution.
Thanks for your help.

Search around, it's not difficult. You only need to accomplish 3 things:
1: Remove the flybar mechanics and find a link that will fit from the swashplate to the grips. (measure before disassembly)..

2: Fabricate/purchase a swash driver. the easiest is Vario's swash drivers. Or, you could modify a washout base to clamp/screw to the main shaft, and the washout links will drive the swash.

3: Reduce your mechanical throws, either find a longer grip arm or use shorter servo horns. Since the flybar controls roughly 50% of the blade pitch, removing it will give 100% to the swashplate. This will mean your throws will be twice as far as they should be. Reducing mechancial throws is the best way to bring this back into check. You can fine tune everything within the V-Stabi software, but 50% is a good starting point.

Last: Install the V-Stabi and very carefully go through the parameters. It's fly-by-wire, so EVERYTHING must be set at least to the correct direction (both your input movement and gyro movement).

Dave said it right. Its not very difficult, but some things are remarkable.

Read my article at the VStabi WIKI for conversion.

This time i will post the german link:
