Converting a flybarred head to flybarless? doable/worthwhile?

[Telehandler]

Decided to keep my n5 now and give fbl a try I have a couple of spare n5 flybarred heads here and want to know if possible to convert to a reliable fbl head,any advice please .if anyone has done it please could you post some piccies up.

Ive been looking at my K3d with regards the same prospect. Yeah its definately do-able.

From what I can tell is you need the linkage rod to run in perfect line with the mainshaft, and obviously youll need to get a swash driver (£5 off fastlads).

But I have decided to fit the 6hv head as will look better and it has Compass etched on (yeah I know small things etc)

yes it is possible to convert a flybared head to fbl
how you go about it depends on the head

here is a hirobo flybared head converted to fbl to give you an idea

There are a few ways to do it. One way is to attach links directly to the grip arms where the mixer goes on the flybarred head. You'll need some longer link balls or if you can fit different grip arms, basically you have to get them further outboard for the correct geometry. Then just fit a swash driver. I happen to have an N9 head that was done that way and it has plastic grips where the grip arms are part of the grip so there are extended links fitted (about just under 2cm) where the mixers used to be. The pins that were there for the washout base have been chopped off.

The other way to do it is to leave the mixer arms on and take the end that was attached to the flybar and have it linked to a stationary point. This is how some of the JR FBL head conversions are done.

Ive been weighing that one up Sheryl fer when I get round to it. And looks like all I need on mine is the swash driver and arms, and use what I have already, but have u seen the bloody price JR want to do it properly??

And you thought my £70 tail repair was expensive................................

Yeah JR stuff is quite expensive as is Hirobo. I really like the look of those JR three blade heads but they're like £250.00! something like that, silly money. Usually with just a little enginuity you can mod a FB head. There was a thread on here a couple years ago from J S Q about modding Align heads using the existing washout arms turned 90 degrees and connected to the grips where they used to connect to the flybar and I have seen a couple new FBL helis using that approach where the swash driver doubles as the input from the swash to the grips. I managed to track down the FBL headblock for the Rave as I'm converting it as well, just need to figure out what it's going to take on the linkage.

This is how I did mine, the same as this Kasama Shrimok head. Just add a ball and fix the pitch link to the mixer arm.

Hi,

It is possible to convert the standard flybarred head as in the picture posted by Rctintin, you will however get better resolution for your FBL controller with a true FBL head setup.

The inner swash locking assembly is available as a complete item if required for the conversion of the original head (Part No: 200-409)
200-409 FBL Inner Swash Locking Assembly

Complete flybarless head assembly (Part No: 200-408):
200-408 Synergy 50 Size Flybarless Head

Hope this helps,

Hi,
I converted an Audacity Pantera P6 to FBL following the instructions on their website. Set up using a BeastX and flies okay.

Had to modify the washout base and arms.

Maybe in some cases depending on the FB head but in general terms there's nothing magical about a FBL head and many FB heads can be modded to work just as good. One other difference is often that the FBL heads use harder dampers.

Someone somewhere has probably worked out an ideal ratio of servo to grip movement and the optimum setup would be as linear as possible but even without those specs we can easily look at a number of FBL heads and see what generally works. I suspect also that the linearity and ratio is not super critical because the FBL controllers will simply move the servos as far as it takes and adjust for all the changes of geometry. The main thing would be having enough resolution, similar to the setup of a tail servo and linkage, there is a threshold you want to stay above in terms of servo resolution and FB swash linkage is often able to supply more deflection than you need at the grips, hence the need for some reduction via levers or longer grip arms.
