Vbar Mini Blueline w/5.3 Express Firmware & 3 Bladed Head

[tshelby73]

I'm not positive but I believe vbar is looking for 80-100 at around 12-13 pitch. I know you don't need that much but maybe set it up that way and use pitch curves to lower it back down to the 10 you need.

Someone else will need to verify this as I'm just doing my best educated guess.

When I started setting up the new model for 3-bladed in the vStabi software, in the COLLECTIVE tab I just adjusted the slider to whatever would give me +/- 10* of collective pitch. Unfortunately I wound up w/the slider way down in the 60 to 65 point range which was well below the software recommended range of 80 to 100 points. Same thing happened w/the CYCLIC tab. What can I do to get these throws within the suggested ranges? Could it be related to my 3-blade head servo to swash linkage rod geometry?

You need to move the balls in on the servo horns.

+1, you can even see the links are at an angle. Shorten your servo arms and you will be able to increase the numbers in the Vbar.

Not sure what that will do for your feeling of it being off.. Could you explain what is wrong?

+2 on using the hole closer to the servo, not the one in the end.
The lower numbers for a lower pitch shouldn't matter too much but if your cyclic numbers are low, you must fix that.
I had a NEO in a Blade 300x and had low numbers. Couldn't use the inner holes as things would bind.
Thet heli never flew right.
Sold it and bought a 450. Installed the same NEO on that heli and got good numbers, it flies great.
