Hoverfly never did mention their big release did they? not to change subject.
Gave the Super X/Discovery combo another go at the field today, I'm not liking this combination much. Seems impossible to find gain settings that work well on the Discovery frame, I think the big problem is the lack of fine tuning ability the gains can only be changed in increments of 1 rather than fractional increments in between like the other flight controllers I use. I have to say this same Discovery flew much better with a Naza on it and that same Naza is going back on it this week, I've tried my best and can't find settings that give the Super X the flight quality I'm used to without being "pitchy" or having serious oscillations in FF.
The X will go back in the box for now and when I get some spare time I'll give it a try on a standard quad frame. I was hoping it would work well as a Naza replacement but given that the majority of the FPV frames I have are asymmetrical it looks like that isn't going to be the case, I'll have to stick with Naza and Multiwii for those.

Ken I think the gains can be changed in increments of .1 not 1 which should give a user more fine tuning. Below is the way Drew for Xaircraft America explained it to me. You have to look at the Black Box data to see where your G gains are actually set to get the most accurate reading.
From Drew: The gains you set in the software adjust each of those parameters and the gain on the knob is a separate "overall" gain that adjusts as a percentage of the gain mix you have set in the software. For example if your G is at -60% then you are running your quad at 60% of the mixture of values you have set in the software.
I see no way to make changes that small with the sliders in the GUI, it just goes from one number to the next. No matter where I have put the GUI gains the adjustment knob either makes it too soft to be stable in FF or there is constant visible oscillation there really isn't any in between where it flys like its well balanced. Some of the twitches are actually scary as I usually only see things like that through the goggles when something is about to go horribly wrong.
For whatever reason the Discovery frame can be a challenge for some flight controllers, took me several tries to get one stable enough with a Multiwii to actually be able to fly it without it trying to crash everytime it started FF. Still working on the tuning with the M/W but it flys quite well even with the little bit of jitters I haven't been able to smooth out yet. The X just isn't happy on this frame and as I said in the previous post, this Discovery flew really nice with a Naza on it, all I did was swap one flight controller system for the other, nothing else has changed.

Hey RTRyder, the issue is with the untraditional X on the Discovery, the SuperX does not seem to like it very much for some reason. XA knows about the issue and hopefully will be addressing it in the next firmware update. That being said, if you put that on a regular X it will be rock solid out of the box.

logically speaking, why does it make any difference? I dont think any other controller has a specific layout for the asymmetrical layouts either. Also, as these are not closed loop systems, how does the controller know where the motors are placed? I'm just curious why it is different if you can run an XY8 with the x8 config on Hoverfly, wookong and MK.
I have the manual for this AD1, an asymmetrical quad, and it shows it having a SuperX controller installed on the quad's . I mean hell its in there own owners/build manual. Here is the picture taken straight from the manual.
So it must be possible, otherwise how did they get this quad to fly if it doesn't work?
