Blade stop auto

[Geek]

Right have people been doing blade stop auto's on Flybarless?
I tried one yesterday and was shocked at what happen

The model slowed the blades so I could count them model looked like the nose had dropped so pulled the stick back but all I did was flip it inverted tried to get the blades to spin up. wasn't having any luck so woost out and took the hold off in normal mode then luckily it spun up.
I was a Lucky man so will lay of them for a bit.

Is Flybarless harder to start blades back up?
I love autoing the Flybarless as it flies with so much more power at the end

I would imagine that the flybar is better for blade stop autos as the flybar acts as stabilizer

Not when it's stopped!

The gyro trys to correct the head thinking it has a good headspeed as the speed is low it will give a big movement hence the inverted fun!!
I'm using the vbar and have a memory bank setup nice and soft for blade stoppers...

[Ashley Davis]

Daren is spot on, remember flybarless acts like a heading hold gyro, so when you put in the control it demand a certain flip rate in terms of degrees per second. If your headspeed is really low then this will result in a massive cyclic command as the head will respond very slowly.

You need a flybarless system that does one of two things to counteract this ......

1. knows when you have hit hold and swaps to a rate mode instead of heading hold for autorotations
2. knows the headspeed (ie. has a governor of some sort built in) so it knows the headspeed is low and can adjust the flip demand rates accordingly

The only one I know of currently that has either of these is the new Curtis flybarless system (there may be others, this is just to my knowledge).

yes, the flybarless kit will apply more and more cyclic looking for a response, but it wont be getting any becuase the blades are stopped.
when you pick up a flybarless and carry it with the blades stopped does the swash not tip right over and wobble about in response to the helis every movement? thats what it will be doing when you do the blade stop.
so when you powered up again it probably had the swash topped right over, even if your stick was in the middle. So I reckon you were very lucky indeed!

Powering out of the blade stop - I guess you must have had the blades pretty tight in the grips!

Thanks Guys so if I lower the gains it would make it better

The swash does move when walking but not that much.

The powering up I must of been lucky as I didn't do blades up just to do blade stop auto was just how tight I run them so I might run them a little looser

Thanks

you nutter Paul, just can't stop yourself.
Never tried them on a fbl model yet, and after reading this i don't think i will bother....lol

Thanks James it's a bit of a heads up for you
Next time we are out I think normal auto's for me

The only one I know of currently that has either of these is the new Curtis flybarless system (there may be others, this is just to my knowledge).

So that would explain Curtis's auto masterclass video using a flybarless 700, especially his final inverted, rolling, bladestop auto.

I think this was explained in the first RC Heli Nation podcast in an interview with Curtis. I didn't fully understand (I've only got an esky co-ax), but he seemed to be talking about the same stuff as you guys, and he mentioned that his system was special... :-)

The CSM system was always capable of this. Unfortunately as they didn't write a flybarless specific manual and alter their 720 programming software to make it obvious to people what each window did in regards to a flybarless head it was not widely adopted. I ran with it for some time, and was supplied special settings by Andy at Real Raptors and it performed pretty well. Had edge blades been out back then I might still be running it. It was as good as most other sytems out there, and better than some of the more recent ones.

s***, that coulda been nasty, good your engine didnt stop, i did a blade stopper before and the blades stopped, folded up, so i flicked back in and the force of the power coming back on and the air on the blades cracked them straight accross the blade but i managed to get it back down and get some new one back on.

From what i've seen so far the Curtis unit Total G will be the daddy of all fbl systems especially when it comes to Autos, again just from what i have seen the Total G has a separate set of parameters that are only employed when you hit hold and the HS drops to a certain speed, As stated already his Autorotation demos are awesome and its fair to say it works!

On what Callum said, i would of thought along similar lines mate but more so that the blade restart would be much easier with a fly bar as stirring would bite the air with the paddles and get it spinning again.
