Hi Guys,

I'm trying to learn 3D and I'd like for the cyclics to remain fast but need to soften the sticks around center.

Is it better to adjust expo using the radio (DX7) or through the software (or both)?

Thanks in advance.

Either way works, I like to tweak it in the radio and leave Linear in the program.

Light is about 7%
Medium = 15%
Deep = 30%

Just like it was said you can do either or run both. I have, but I prefer to run linear in the vbar on the head and tail and run both in the TX like a regular flybar model. I run 35% on the cyclic and this is plenty numb. Like 25% on the tail. Try and see what you like.

I set the Vbar in the Aurora up to be "linear" in the program...meaning you need to set some expo in the radio....

as others have stated...it's the BEST way...the expo curves in the vbar program never felt quite right for me so I always go linear in the program...

It's all preference really. Try both and see what you like better. Just make sure not to enable expos in both the TX and the Vbar at the same time.

Me personally I like my vbar cyclics at linear but I like the vbar tail expo. There is no right or wrong.

I have been running the cyclic and tail expo in the V-bar unit itself. It works OK, but I think it would be better if I put it into the radio instead.

There is one difference, if you run Linear in the program and Expo in the radio it allows for higher piro rate than if you run expo in the program (there is some "upper" limit built in when using expo in the program).

Thanks for the input everyone.

I was reluctant to put expo on my radio because I thought everything needed to be adjusted via the software in order for the VBAR to work precisely/accurately. Well, we know better now. I'll start with linear on the program, set expo @ 7% on the DX7 and work my way up to my happy place.

Anthony -I was flying the Aurora on light setting.

Linear was too twitchy. When you told me over the phone to give it a lot of expo, you weren't kidding. I must admit that I needed to dial down your set up quite a bit. My flying skills have not matured to that level... yet

Thanks again guys, much appreciated!

Just to give you an idea with settings to linear on my DX7 i run upto 35% on cyclic and 55% on rudder.

I've run the Expo linear in the VBar and 15% in the Tx. Just tried using the Expo in the Vbar this last weekend.. Don't really like it much. On medium it felt like there was a delay in movements. Light wasn't too bad but still didn't feel right. So i'm going back to Linear and expo in the TX.

I was using the dual rates also to get the cyclic pitch to a managable rate. Everyone says to shorten the servo arms on the Synergy to 10mm. Tried that also but didn't care for it either. You see any harm in doing that for the cyclics?
