Flybarless Rotor Head Systems > Flybarless system for 3d and AP

Can anyone advise a system that has the benefit of Horizontal hold like the Helicommand Rigid and the 3d capabilities of v-bar?

Can the rigid be used for 3d with a flybarless setup and 'switched' to a higher gain for stability as a bail out.

I currently have the AP2000i with a flybar and would like a similar type setup without the flybar.

Thanks

Fergus

If you have AP2000i and you want to remove flybar you must add two gyros GY401 for example, for ELEVATOR and AILERON

Helicommand Rigid works good on 3D also

I think I will sell the AP2000i and IR sensor rather than use it in a flybarless setup. Using two 401's is not ideal and I am waiting way too long for Angelos to release the inertial sensor unit and altitude hold unit etc.. we heard about a long time ago.

As it stands the AP2000i is fine and I am not trying to run down Spartan RC. I bought the DS760 gyro for my Logo500 and think it is great and have got great value from the AP2000i since I installed it. But I like the idea of going flybarless on my Joker2 and would like to have as aerobatic a setup as possible with the addition of a stable platform at the flick of a switch.

I will look closer at the rigid in 3d flybarless applications. Are there any other systems which should be considered?

Just doing more research and it seems the gyrobot from LF-Technik would fit my needs well. 3d capable with stability at the flick of a switch. Anyone got a release date?

It seems the Helicommand Rigid has a weak tail gyro so that is out unless they release an updated version.

Anyone else know of other products out there?

I dont know anything about Angelos´s inertial sensor...
AP2000i + 2 gyros are only for CCPM helicopters, if you have H1 Heli you only need 2 gyros to replace flybar.

But you have other flybarless sytems:

AC3X http://www.eheli-tuning.de/ac3x.html

GyroBot http://www.lf-technik.de/shop/index.php?language=en

ProBar ( by Eco8gator ) search more info on Run Ryder http://www.runryder.com/helicopter/t413445p1/

SK360 ( by alvinchai and Bruce2.5D )COMING VERY SOON http://www.runryder.com/helicopter/t402647p1/

Others: CSM Cyclock, AP2000i, Helicommand, V-Bar...

Gyrobot price is more than 1.000$ and it has 3 axes.
If you have a good gyro like DS760 you only need 2 axes for ELEV. and AILE.
I think Gyrobot sensors are not better than DS760 or GY611 sensors..if you want to pay for third axis that you are not going to use to replace tail gyro is your problem.

The DS760 is on my Logo500 not the Joker2 which I will be using this unit on. I was just trying to say I am not anti Spartan RC.

Maybe you misunderstand what I am looking for. I want a system that offers 3d performance like the v-stabi and the stability of the Helicommand in one unit for a flybarless head. Gyrobot is a little cheaper than the v-bar from Mikado and offers the benefit of switchable levels of stabilization so it seems the best candidate so far.

The Helicommand Rigid is not up to it for all out 3d from what I have been reading. Nor will the Ap2000i as using gyros will require deactivating the IR sensor. I think the V-Bar does not offer switchable levels of stabilisation.

Thanks for the links to the other units. I will read up on them.

OK I have been doing more research and it seems the type of unit I am after is not on the market yet.

Probar - not released (don't know if it offers stabilization like HC)

AC3X - does not offer HC like stabilisation.

Vbar - Does not offer HC like stabilization.

SK360 - not released (don't know if it offers stabilization like HC)

Gyrobot - Ticks all the right boxes (not released yet)

So unless anyone has another suggestion it seems I will have to wait for Gyrobot to be released or for an updated Helicommand Rigid with a decent tail servo.

I am in the early stages of researching Flybarless for my J2 so please someone correct me if I have done any of these systems an injustice.

Why you said other systems dont offer HC like stabilization ?
Do you think HC is the best of world ?

You cant give arguments without proving them. At the moment you have only seen videos on youtube, you must hope to see that other people say about all new flybarless systems like SK360, ProBar, Gyrobot and AC3X.
I know HC Profi is so good but for cientific experiments only, it is very expensive for our hobby.

I am not referring to the Helicommand Profi I am talking about the Rigid. This system will return the heli to level when you release the cyclic stick but it is not suitable for 3d due to a weak tail gyro. The questions I posed are if the others would do the same. As I understand it now they do not - instead they leave the heli in the same attitude when you release the cyclic stick (with the exception of the gyrobot which will have a function similar to horizontal hold on the Helicommand Rigid). In other words the others are more 3d orientated.

A gyro system which replaces the mechanical flybar is one product a stabilizer which returns the heli to level is something else. I am looking for a stabilizer for flybarless Aerial Photgraphy but which is also capable of 3d performance for when I remove the camera mount and need make a single adjustment (via a switch on the Tx).

I am going to close this topic as I seem to be repeating myself. No disrespect Andika. Thankyou for your input and replies.

I purchased the Gyrobot yesterday for my Joker2 so this topic is no longer relevant to me anyway.

I hope now to have a system for all out 3d which with little adjustment can also provide a rock steady hover for aerial photography . Time will tell.
