How to put mini VBar in Rate mode
May 27, 2011 06:45AM
How do I put VBar in Rate mode? I see a Rate mode button in the advanced tail settings, but it's difficult to tell if the button is actually doing something. And when I do push the Rate button, it looks like it stays highlighted in both bank 0 and 1, even though I selected it only in bank 1.

The reason I ask is because I would like to put my VBar heli in rate mode to set up the tail rotor mechanically. That is, I want to put the heli in Rate mode and then adjust the linkage so the tail holds in rate (the way I have always mechanically set up a tail).

Thanks for any help!

Hi.

Well, actually this is not necessary, if you do it this way:

Servo arm as close to 90° to housing in setup mode, powered on.
Then power off, move it exactly 90° to housing manually, and adjust for 90° crank at the tail rotor (for most makes this is default), then you should see approx. 2-3° of pitch at the tail rotor.

Then do the trim flight an VBar adjusts for you, more accurately than you could do in most cases, and without the hassle.

But:

Rate Mode sets the I value (integrator, heading hold value) to zero.

You must have VBar connected and set to Bank mode (0/1/2/3) to access the banks separately from your tx, although you should be able to set it by "Edit Bank #" anyway.

OK, thank you. I think I understand that...

I would feel much more confident with VBar if this kind of information was written down in a setup procedure somewhere in the manual. As it is, I often feel like I am tampering with the settings of a black box, not really quite sure what I'm doing...

I do appreciate the speedy tech support when I have questions!

Yes you are right.

I tried to write this in a article here, maybe you didn't find it:
