I've just setup and flown my first vbar and absolutely love it. I've flow the cyg,align and Beastx and this one is hands down the best I've had.

Only thing is that the roll and flip rate were a bit slow so I upped the " agility slider" from where it was at 80 to 100. I didn't notice a real difference.

Maybe I adjusted the wrong slider?

Any input is appreciated.

Thanks

You can adjust the 8 degree portion of the setup to 10 degrees and you can also adjust your endpoints in the tx wider. What are your setup numbers now?

I did the 8 degrees only and end points are at 100 for ail,elev and pitch. I see you can go higher with the slider than 100 but the color on the menu showed it in red once you do that which I figured was not good.

Thanks

The 8 degrees is a calibration point for the vbar. Calibrating to something else will not effect the pitch and roll rates, it'll only throw off the calibration point.

Bob, please do not respond. You are wrong, once again.
OP, the 8 degree setup and endpoints will do exactly what I said. Try them one at a time and advise. BTW what Helis is this?

Yep, roll with it. That Heli should be pretty fast anyways, tried turning up the HS as well?

I don't know if the current software does this, but in older versions, I found that if I did a bunch of mild flying with the optimize cyclic turned on, the optimize numbers in the cyclic advanced menu were lower than they should be and slowed down the cyclic rates.

The numbers for cyclic optimize should be 1/2 of what your agility is. If not, turn off the optimize and raise them so they are. Keep the ratio between them the same.
IE: if your agility is 100, but right now your optimize numbers are 30 and 40, change them to 45 and 55. You can turn the optimize back on after making the change. Then try a test flight but be careful as this can make quite a difference in agility if they were out a lot.

Doing this, you don't mess with the reference settings for the collective or the radio channels. Like I said at the start, I don't know if this still happens in ver 5.3.4 but it is something you can check.

It's poor advise. Been discussed. See MrMel's explanation here.

There are better things to adjust. Like optimizer.

Btw I have done it on both my machines, I like a sick flip and roll rate as well. They both have suffered no changes in any other flight characteristics. Some of the Mikado pros so it as well (10 degrees).

Please do not raise the Cyclic step and overdrive the system.
Raise Optimizer manually if you need faster cyclic where agility slider makes no difference anymore.

(also make sure Cyclic Ring is not set too low as it's the hardlimit which no other can override)

Overdriving the system might work but you might boomstrike and have a totally dead bird, I have to sit and say the condolences to those (already happen).

Going outside "the base" on the system is fully possible but should really only be used if you FULLY understand every aspect of cause and effect.

So it can be used if necessary, just not in a "general" sense. I have done this since IRCHA with my XXtreme, Goblin, and Logo 400SE with no ill effects, boom strikes or any other things based on the recommendation of a Mikado pilot. I know the "red" are is to be avoided but 10 degrees is easily achievable without getting there. 'So to be clear, is the issue the 10 degrees or the "red" area??? I realize some can get there with a bad setup as well.

Cyclic step is old Cyclic gain in v4, 10 degree is outside what optimal, period, 20% outside.

You overdrive the system, you speed up the control loop, put more strain on the servos and so on.

As long as you have high end equipment, no issues.

But if you do not, your gone.

Simply, my view is that it was wrong by pro's recommending it in public for the Logo 700, keep to 8 degree, use other means or after a review of the vbar file as a whole I can say if it's Ok.

Because if you take your recommendation of 10 degree, then you choose to use some others for lets say cyclic ring options, you have a total crash.

Ok but what does " raise optimizer manually" mean.
I'm away from my PC so I cant see the software but do not recall a tab named optimizer?

Thank You

Manually raising the agility

Optimizer values are under expert cyclic (they change when you fly with optimizer on)

MrMel, thanks for the clarification. Glad I use high end stuff I see that it may not be optimal in all situations....OP I APOLOGIZE, please follow MrMel's advice as mine might work for some but NOT for all......Ron

Had one set up to 14 degrees. That was a BAD @ZZ machine alright. No problems.
But, 8 degrees works better in the end.
