Just trying to grasp the edge of flybarless technology.... I was wondering about all of the flybarless units. They essentially are only a pitch and roll gyro system if I am not mistaken. Most include a yaw gyro also.., but my main question is why do you need a gyro on pitch and roll?? Why could'nt you just have direct mechanical linkage setup and fly it that way. Maybe I'm being narrow minded but the mechanics are already there. I've been thinking of removing the cage on my trex 600 and flipping the main grips to make them leading edge pitch control as opposed to trailing just so the swash could move int the same direction as designed. This was just a thought because it seems to me that all of that money for the flybarless unit seems to be a waste of time. It really to me seems like it does nothing more than a heading hold gyro does. Anyways feel free to educate me.

I thought like the way you did before and wasn't really a flybarless believer. Since i got a new Logo 600 flybarless i noticed alot of deffferences between the two flybar and flybarless. One thing i can give you for sure a fact is the stability when hovering upright or inverted. Less correction and more manageable to control. There is something about the flybarless i can not describe, but one thing for sure i can say is you will not regret it!.

There are people who have figured out how to fly without the electronic units,

Similar question was asked here, https://rc.runryder.com/helicopter/t544894p1/

Yes, you can fly it without electronics, some even claim it flies good, I have flown both with and without, so has friends of mine, and no, it dont fly as good as electronic stabilized, not even close.

as you remove the paddles you get some ill effects, you also get more travel with direct linkages, so it would be wise to use some type of mixing.

with no electronics you have two things you can tweak only, weight of the heli and blade type, those two will be the only thing you can change to make the heli fly better and get less "ill effects"

but it will be skittish, and it will balloon up in FFF, also you will get some spiral/wobble at piroette flying.

But it will fly.

with a good FBL solution you get non of the ill-effects, and you get a really good flying machine, with more power then using paddles.
the increase of power comes from the ease of which the heli now can turn without gyroscopic stabilization from the paddles.

Okay was just a thought. I know if you did make it direct to the swash your EPA's would be a third of what they are with a flybar. I too like everyone else in this area has gotten the Flybarless virus, Just was weighing the options. It's just so hard to drop 400 to 500 dollars on a FBL unit when I know it only cost's about 40 dollars to make them. I wish Carlo had his stuff readily available.

Its not the hardware which is complex (however, just processor + 3 x Analog Devices Mems > 40 dollars..) its the software and time & effort put into the development.

In no means am I trying to be ignorant... I know what goes into writing the programs. I just wish it was just a little cheaper. I dont have what you call a liquid budget. The V-bar is just way to rich for my blood. I know they are probably close to the pinnacle of engineering but 600 dollars for a complete system is hiway robbery. The old addage is true i suppose, Is the juice worth the squeeze?
In the case of flybarless, HELL YEAH!! I just love the way a FBL heli sounds in the air, It's incredible, makes my hair stand on end.

This may well be the answer for those without deep pockets, and it may even surprise us.

Thanks to Heli-cuzz, I finally tried 'naked FBL' a couple weeks ago,
and the first session I just wasn't sure about.......but it was low
light at the end of the day and windy. Couple days later, tried it again in much better conditions, although I only got a flight and half
in, I was very impressed! Made several straight-across-the-field passes and NO pitch-up at all/ stationary,consecutive rolls till I got tired of em,etc. Even the few autos I tried seemed to be as I was
used to.

Not saying I may not eventually go to a 'stab' unit, and not saying it
flew perfect in every way......but, I am certainly looking forward to
getting back to the field w. it!! Weather has basically nixed all that for now......but for the way it flew and saving $300-400 (for now).

And, yes, would definitely use a dedicated FBL head, not just pulling
the paddles......

With the advent of the mini VBar and the new Satellite Ready VBar I would presume there are some older Standard VBar units on the used market. In fact I picked up my first VBar from a reputable used source here on RR. Also there are artiles and posts on how to modify a standard FB Trex head to make it a FBL head with no additional parts or cutting or grinding. So if you are interested you can go FBL for somewhere around $300+ and then if you choose to sell the old Gyro you can cut it down even further.

It can be done for considerably less than $600 and even probalby around $300...

IMO it is worth it If it really comes down to $$$ then stick with the flybar and save your $$$ so you can do it right. If helis flew perfect without flybars and no stabilization (no tendencies etc) then there would be no need for the units that are out today.
As to the naked FBL helis, they will work but never as well as with a 3 axis system. When you fly a properly setup FBL heli, things like wind and such become a thing of the past. You have to try it to understand...........Ron
