Search "Nobar" on here

I'd give credit to who coined the name but I forgot...

I believe it was HeliCuzz.
And yes, it works. I've flown it in a Raptor 50V2 FBL with a GY401.

NoBar does not mean no gyro.
It refers to an FBL head being controlled only by the radio's mixing. The term does not mean no tail gyro.
A tail gyro is used. Or the cyclic gyros are turned off.
The helicopter is completely controllable and simply has no gyros controlling the cyclic.
It works just fine as you realize when setting up the mechanics for a FBL bird that the cyclic gyros are turned off in the test flight to verify the mechanical setup. Exponential settings are turned up higher to help tame down the very quick response from the FBL head.
My hat is off to anyone wanting to try no gyro at all, but that is not what the term means.

Hi Wayne, hope you are doing well!

Helicuzz sounds familiar. I'm pretty sure that was the name.

To your question unruly_heli_nut:

I read a post once where the pilot flew an entire flight only to find out when he landed that the cyclic gyros were turned off. It's kinda like that. It will not correct for the wind gusts and stuff, but it doesn't get in your way or argue with you either. It cannot accidently tip your bird over. You might, but it won't be the gyros. You are in complete control of the bird with a really smooth and quick head design. Personally, it is too responsive for me and I had to set my exponential to 35% to be comfortable.

Thanks for comments, should have remembered my basic Bell-Hiller cyclic stuff. If memory serves right, without flybar, it's Hiller only. Or was it the other way around... can never remember. Or maybe it's neither.

Flybar is a Hiller adaptation.

Helicuzz is a good friend of mine. He definitely coined the term NOBAR. His play on words referring to flying FBL without electronic stabilization.

In my experience with NOBAR, there's no real increase in sensitivity in the cyclic. The feel is a little different because you're not "fly-by-wire" anymore with the FLB unit doing the inputs through its control loop, but it's not more sensitive. It's actually more natural feeling, especially with no wind.

In fact, I'd suggest taking out any expo. With a wind or in FF you have to hold control inputs to counteract tilts of the rotor. Expo really exaggerates how much stick you have to hold. I find it quite uncomfortable having to really throw the stick around with any expo in the AIL and ELE.

The CGY 750 + 8FG radio is the ideal combo if you want to fly NOBAR. I setup a seperate set of gains on a switch but the AIL and ELE are simply set to 0. I then set the expo to 0 in the unit when switched to that bank of gains.

I'd try it first with little to no wind, because it's pretty shocking what the uncontrolled rotor disk does at first. But you get used to it after a while and it's a lot of fun.

I have a five bladed head on a Hughes 500 with Raptor 50 mechanics and no stab unit installed.

My buddy and mentor Emile (Copterdoctor) did some mixing in the Tx and it flies well.

I have a four bladed head on a Century predator with no stab unit that has no mixing at all and I have a video to prove just how smooth and stable it flies. Emile's Bell 407 with the same mechanics and four bladed head flies just as well as I got to hover it in a good wind and had no problems holding it in a steady hover.

I have been told repreatedly by folks with more knowledge and experience than I that with a stab unti I will enjoy it more especially when flying in wind so I purchased one to try on a Long Ranger with Raptor mechs and a two blade FBL head.

Interested
Are those of you that are flying this way doing 3D style flight? Or just basic forward flight like an airplane. I have a trex 700e and a DX7, would I be able to mix this in my radio? Would love to try it. And are there mods that have to be done to the head?

Did he crash? Dang, I missed it!

Aces:
My experience with NOBAR was brief and I only flew basic FF circuits and hovered. I was just getting started and that probably explains my perception that it was so sensitive. I had come straight from a 50V2 with flybar set-up mild for a beginner. It definitely was more responsive than what I was used to. I soon got the CGY750 at the advice of several folks, hence the relatively short experience. But, it was stable and controllable enough for a complete noob. No reason that I wouldn't try it again. The ultimate in simplicity and minimum of maintenance.
Here's a link that should explain a lot.

After watching these videos again, I definitely want to try it again.
