Devo protocol >=8 channels only?

Right now I discover that Walkera QR Ladybird doesn't accept GEAR channel for switching 6-axis/3-axis flight mode at 6 channel mode. Earlier it worked. Seems that QR Ladybird now always see 8 channels and wait switching flight mode at AUX2 channel.

Is it right? Devo protocol haven't real 6 channel mode?

devo.c
//FIXME: Properly set number of channels;
num_channels = ((Model.num_channels + 3) >> 2) * 4;

((6 + 3) >> 2) * 4 = 8

It has been this way since the beginning of time.
I only support emulating 4, 8, and 12channel Tx.
If you set the channels to another number, it will always round up to one of those values internally.

You need to configure the channels as if you were using a Devo8 or Devo12 tx, but this has always been the case.

Actually I agree with Vlad, it was that way in the first one or two release.
I had the gyro (actually flip mode) on ch5 for my Ladybird too, but it was long time ago...

It's surprise. My first config for Ladybird worked with GEAR channel at 6 channel mode. Since that time (3 months 2 weeks ago) I didn't check this up to now.

I've changed my config for Ladybird at forum.
