2014 Quad Frame in 'discovery' layout (V frame type?)

Archive

The 2014 X4 frame has another set of bolt holes in base plate for mounting rear arms further back, similar to a TBS Discovery. I went with in the this ‘Discovery’ style to help balance out a front-facing gimbal (and frankly it looks good). My maiden flight was a little twitchy, and rotating yaw 90 degrees sent the whole thing into a serious wobble. My frame type was X for this flight. However, I noticed in the newest APM Planner when setting up the newest firmware that there is an option for a ‘V Style’ frame which looks like what I have. My understanding of ‘V Style’ frames is that the rear motors are angled (or even inverted). I could just fly and see but my flights are few and far between at the moment so I’m trying to make best of downtime.

I haven’t been able to find much documentation on this new ‘V Style’ frame setup, is this just for tight inverted/angled tail setups or ‘Discovery’ type styles. Is anyone else flying the 2014 X4 frame this way?

Thanks.

You’re mixing up V-tail and V-frame.

V-style frames are supported already a while.
V-tails are brand new in the software.

Thanks so much! Part of the trouble doing research is having the terminology correct. So I’ve got a V-frame setup.

I’m hoping to find a bit more information regarding the angles in the source code. I need to compare how far off mine are to the values in the code…

I will do some research and post a formal question there.

But for anyone interested, yes, after selecting the V-frame layout during setup I was able to yaw without wobbling like crazy. Copter few much better (but needs some serious PID tuning as a separate matter)
