Vbar flip rate setup

[helimadness]

Hi All.
I have been playing with the flip and roll rates on the Vbar. The problem I am having is with the servo ball links on the inside hole (standard Align alloy ones) With 11deg collective and 12 deg forward ele it bottoms out on the anti rotation bracket. Even with the collective only half way up say 5-6 deg it bottoms out with full forward Ele.
At the moment I am sure I am not using full forward ele and full collective at the same time but it just doesn’t seem right so keen to fix.
In the Vbar setup the cyclic and collective numbers are at 70 to get the 12 and 8 deg with the servo links on the shortest hole. If I moved out to the outside hole the link would clear the anti rotation bracket but the setup numbers would be say 55-60. Even 70 is out side there min suggested range of 80-100. What happens if you get too low a number in the setup?

To get 12 deg Ele I had to drop the DR on the Ele to 55. This made the flip rate really slow even with the Agility slider at 115. I increased at the field to 60 on the DR and the flip rate is ok but certainly not super fast. With the DR on 60 I assume now around 13-14 deg cyclic which seems like a lot.

Another option I was thinking of filling out the Anti rotation bar a little. Wouldn’t take much to get it to clear.
Or go back to the outside holes so everything clears but would be well outside the recommended setup numbers on the vbar.

Basically it is flying real nice. Just this small setup problem that is bugging me so keen to fix. Also no real range left to speed up the flip rate.
Havernt played with the Style or Gyro sliders yet. I assume they wont effect the flip rates just the way it feels. And it feels great.

Just remembered. I have zero on the Exp in the radio and 15 on the Vbar software. Maybe I go to zero in the software and see how that feels. Got the Bank switching setup now so might give that a go.

How it works on the bench is different to in the air...is it a 550?

I have a question:
Did you measured those angles in cyclic setup menu, isn't it?
You should set properly the cyclic value, then tweak the agility to obtain the desidered rate.
You should also set the cyclic ring value to avoid binding or extreme travel of the swash.

Be sure to not use dual rates on tx, you need to see 100% of travel of value in transmitter setup menu. Every limitation to the travel must be dome via setup.

Hi
When I did the setup I set the Collective to 12 and the cyclic to 8 as per the instructions. Once setup was finished I checked and had about 14 deg. There doesn't appear to be anywhere in the software setup where you can adjust cyclic travel in flight mode. Also the problem is the binding is only at the extremes of collective and cyclic together.
The easiest solution would be to go to the out side holes and all would clear but the cyclic travel number in the software was 55 ish from memory.
My understanding was DR was used after setup to control travel. I think Mr Mel videos explained this.

>> There doesn't appear to be anywhere in the software setup where you can adjust cyclic travel in flight mode

The parameter is 'cyclic ring', at least in the pro software. Setup, swash page, click the little blue clown hat.

It has nothing to do with dual rate or expo.

You can only go from the settings in the Setup part of the program when your connected to the computer.

Once your out of the setup program the control loops take over and you'll see strange things like to much cyclic movement, as the gyros are then active and while sat on the bench your asking it to roll, the gyros don't see a roll happening so the system puts in more roll to try to get it roll over still nothing so it adds more till it locks up on something.

Set up like it asks you to in the software and then adjust the Agility setting to speed up or slow down the roll and flip rate, It's very simple, just follow the steps in the setup from the beginning to the end and it will fly very nice, and leave on the inner holes on the servo wheels

Exactly so set the cyclic up in the software at the 8 deg it ask for and then when in flight mode you may see a lot more. on the bench I had 14 deg.

It is flying really well and I can easily achieve what I want from it in terms of flip and roll rates.

Problem is on the inside balls it binds up on too much cyclic forward and + collective. Maybe ill put a red make on the antirotation bracket as a limit and camera on the tail and video how much I use in reality. I think at the moment I am not getting anywhere near the limit but just want to make sure I am not binding my servos up all the time.

Maybe I might have a go at filling a grove in the anti rotation bracket to make more room. Think that is going to be the best solution as not sure I am going to be able to limit the travel and still have it fly how I need.

Might work on rigging up a camera first.

What your happening is normal, Just go out and fly, stop worrying, and enjoy the heli. Like i said before you can't take on the bench readings for cyclic for real, except when your in the setup part of the program.

ok thanks for the advice. Just really like to totally understand what is going on.
Would be interesting to see how much pitch I am using during flights. Not sure if there is anyway to measure that?

cheers
