Well from what i know how a Flybarless controller works Its commanding deflection until it achieves a certain rate of rotation like the tail gyro. If it doesn't sense rate of rotation and you demand a roll for example it would go to hard over making it essentially unflyable flybar or no flybar.. But then what do I know

That depends on the programming. It could be setup much like a mix. The mechanics get the angular rate in the ballpark and the feedback loop tweaks that. Also, we should consider faults other than complete sensor failure.
Actually, with or without a flybar, the fact that a heli will roll hard over due to a sensor failure is just poor design and programming...or they just haven't gotten to that level of sophistication yet. But, that's another topic.

Snowballing - that's exactly what happens. You have an older heli that you'd like to have 3 axis stability on and you get a FBL head, then you find out that your servos are too weak, and have to get stronger servos, then possibly your BEC needs upgrading... etc..

I have some older helis with flybars and I really prefer my flybarless helis because I'm not a pro and they fly better for me.. So I wondered the same thing - with controllers so cheap now it's worth a try.

I can't see how the two systems would fight each other - It looks like so many people got on here to makes posts to get their numbers up. I'll report back my findings when I get around to putting a vbar on an old trex 600 nitro with flybar.

You were just guessing - you didn’t know, but enjoy hearing yourself...????

Been away from flying a while... but I just setup a trex 600n that I’ve had all along - with flybar of course. I didn’t want to sink any more $$ into converting it to a FBL head. Put on a mini K bar and as I suspected it mostly flew great. There was a little bit of oscillation during high speed inverted circles. I’ve dropped the gyro gains down and Im optimistic it’ll do much better next time out. Its super stable and probably a great way for a beginner to get airborne. Cheap older FB heli with a cheap flight controler. After stacking it up put on a FBL head. In hovering and medium speed flying around it was rock solid. It was down on power as should be expected compared to one of my 600 nitros with a FBL head. Which as a sidenote old 600 Electrics work way better when the fly bar is removed due to the increased efficiency.

A mini k bar is not vibration resistant, you'll want to be careful.
If you turn down your gains enough you're essentially turning off the gyro.

My 600N has better power FBL vs flybarred
since the head has less weight and drag from using a flybar .
some FBL units allow the use of a flybar now a days but that wasn't the case just a few years ago.

spending time, paying attention
