it's made for the alien but it is cut pretty close. https://store.rotorriot.com/alien-5-lipo-pad-replacement-black/

Betaflight devs have been working on optimizing code for f7 processers, it's not there yet.  I run 16/8 with the gps, barometer, and accelerometer.  That setup uses 47% of the processor.  Flight controller is powered by 5v from the pdb.  A ribbon cable carries everything to the flight controller.  It's a great setup, completely protected and no worries about vibration, dampners are in place between fc and pdb.  It even carries a uart for changing video channels.  I rate the hardware a 10 of 10.  The code optimization covers all f7 processers, none of them can run 32/32 yet.  I'm sure in time the code will get better, there must be something fussy about the f7's.  I don't regret the purchase and i would recommend it so long as you can wait a bit to run 32/32.  I'm curious to see if the butterflight guys will optimize the code, they are all about high
pid loops.  I have had no issues other than waiting on firmware.

Cool, I just finished my build with the Matek F722-std and I am impressed so far. Running 16k/8k with no overclock(no baro) and getting 30-40% load. Dshot1200 on the other hand I am not so impressed with, but this could just be me not setting it up right.

I have it wired directly to the Ic2, betaflight and inav recognize it fine. It's led lights up blue so I think it's fine. I'm having a problem with the compass fighting the accelerometer, it drifts back to it's original orientation. I'm totally self taught from YouTube so I haven't had any help with this. I'm sure I just need to find the correct orientation, I tried all directions in the cli with no luck. I've just read that I probably need to flip it in the cli as well. I've been strapped for time lately, but I will have some time soon. I'm going to reload inav and see how it goes. Hopefully I can get advanced modes working. The GPS is working fine, I have the home direction arrow, coordinates, and distance from home in the betaflight osd. I really like the confidence that gives me when I fly new areas. I will update after I load inav again.

It works surprisingly well. I've only gone 700 meters away and it's solid that far. I tried it in the top antenna mount as well. The difference is minor at best. No more broken antennas!

Sorry it took me so long to get back to you. The way I have it built with 6mm standoffs, from the bottom to the top of the USB connector it's 19cm. One set of the standoffs are vibration isolators, they are included with the flight controller. You need them with that gyro. The shield for the vtx is on the bottom of the pdb. There is 3mm between the shield and the bottom. 3mm is all you can safely get, unless you take your chance on O rings. That gyro is sensitive to high noise esc's, the racerstar ones I'm using tested pretty low noise and they are cheap. Stick to a low noise esc and you should be good. I'm running INAV now but I'm going to try Betaflight again when the Kalman filter is released.

I forgot to mention, this is freaking amazing hardware!

Thxs for the answers.So all u had to do, if u werent using the gps and was just using the stack for a freestyle build, was solder the camera and receiver to the flight controller? All the other wiring u had going to the flight controller was for the gps, buzzers, and led's?

Yes, that ribbon cable even carries a uart for stick control of the vtx.

So far they have been rock solid. Power is very close to the big names. Glad I watched reviews on these. I can't speak for durability but if I ruin any of them I'll post an update.
