Flybarless Rotor Head Systems > Stratus with CSM flybarless system

Do anybody use the CSM Flybarless system in a Stratus? I would love to have some pictures how you mounted the 2 gyros, especially the roll gyro. Also what lenght on the link on the blade holder should I use? Well I need all the advice i can get! :-) Because I will test this sytem in my Stratus this week.

This is how I did it.



MrMel and I are testing this system on the Stratus. And so far ett seems very good. I havent tested mine yet with the CSM flybarless sytem. But the Mikado System that MrMel used in his Ion X v2 went very well! This head system is better because you can use the full resolution on the servos. And also putting a link direkt to the blade holder just doesnt seem to hold that much, but i dont know thou. :-)

I will report back how it went! :-)

That's funny, I just saw the post on HF MrMel did and I sent it to you. O well. Good luck!

Need understanding

I am not sure I understand. I can understand the gyros to go on the cyclic servos but what does the ccpm mixer do that our radios can't? Why do you need the mixer? When you use the electronic mixer (such as v-bar) how do you set your transmitter up for the inputs needed? I think I would like to try this setup but just want to understand it more.

Thanks

Mike Mass invented CCPM, Inverted Flight and he did it all before 1980

Mixing

Some radios cant do that kind of mixing like the 14MZ can where you can literly program out any and all types of unwanted swashplate movement.

Actually the Tx is set to mechanical mixing mode and and aileron and elevator outputs from the receiver goto gyros. Then the gyros need their output mixed for ccpm (assuming you're using a ccpm setup). It has nothing to do with the kind of radio you're using just that the two axes need to be mixed independent of each other.

I thought he was talking about the Cyclock.

flybarless stratus

Kristoffer

Did you use the factory ma phase ring as your swash driver? and how were you able to mount the short links from the bell mixers to the lower head block? Is that an entire separte piece or did you make it yourself?

Fury going flybarless

Check this setup out.

Wity CSM or VStabi your radio is just a dumb box with 90 degree mixing.

You send Pitch, and CSM/Cycloc or VStabi takes care of it and creates the correct output.
(so in their system you specify what type of mixing you are using, 120 or 140 degree etc)

quicksilver. Yes I made my own link that you screw in the 2 hole on the MA hub. I wanted the short link to be as Straight as possible otherwise when you moved the pitch to the extremes you got a very sharp angle on that link. And yes I made my own swash phase driver on an orginal MA washout. I just turned one washout arm 180 degress so could get more pitch and cyclic from the swash, and connected the link to the swash on the other side of the washout. I have also arranged the cyclic gyros in a different way now to reduse possible vibration when i hade them on the battery tray before. Look at the pictures below.

I have tested the system and it works very good! The Stratus as very fast! Im using dualrate 55 now and the Stratus is faster now and with my Stock setup with V-paddles. So you can imagine when i have dualrate 100! Its a different feel to the heli thats need lite time to getting used to. But you cen feel that you have more power and doing tictocs is so effordless! the head doesnt bog a thing, so its really cool! The system have very good potensial, and im still trying differents setups on the gyros to find the setting that i like the most. And im slowly getting closer! hehe

I have now flown the system for maybe 20-30 flights and its getting better and better and im starting to like it! the manuvrability is amazing! I just want to hear other that have used this system if they find doing pirroflips, and pirrofunnels harder. Maybe not harder but just different with the timing on the sticks. I want to know if this is a setting that maybe could be fixed or if i just have to learn the correct timing for the flybarless system?

I know you guys are doing mostly 3D with your Stratus but how do you think this would work for doing precision FAI/F3C type flying with the Stratus?

What is the life expectancy of the cyclic servos when you go flybar less? Is there any more strain or wear?

This system is perfect in F3C type of flying, I think its to good and that it isnt alowed. I think for competitions in F3C you are only alowed to use 1 Gyro. When you hover in Heading lock mode on the CSM system you can hover almost completely hands off the stick! It coorects for side winds also, also the helicopter is more easy to fly in strong winds. Its very cool! I wouldnt say that it is easier in the beginning thou, but when you can handle the system I can imagine that it can be easier to do Hover Manuvres. The same is with 3D type of flying. I can imagine many say that it is cheating and that it is easier to have a flybarless system. But I can promise that it isnt. It feels that you have to almost completely relearn timing on various pirro manuvres. But I guess its just a matter of practice, to use the system to its full potential. But like I said it feels different in the beginning, but the more you fly it the more you like it. :-)

I would also like to know if there is any more wear on the servos, and if I shorten the life on the servos? Im not sure of that eighter. when you fly with a regular flybar system, the servos constantly work also, but ofcourse the servos maybe work little more with a flybarless system. So if anybody know i would like the answer on that question also! :-)

Sounds very promising Kristoffer!
No doubt you've got me interested into exploring into the world of flybarless flying.
Now all i can hope for is that the CSM flybarless sytem becomes available soon and alot more affordable than the V-BAR system.

Post some videos of your Stratus with the setup if possible

The CSM flybarless system is available and have been so for some time. Realraptors.com are selling the hole kit. I can try and upload a video of it. But Im still working on the settings, wich can take some time. But im getting closer every flight. :-)

How is the fly barless Stratus holding up? What changes have you made since your last post? What is your current rotor head configuration? Pics would be great.

Back off man, I'm a scientist.

Kristoffer gave up on CSM flybarless due to some issues that was not fixable.
I will probably try VBar on mine soon.
