Just built my first Micro FPV Quad- Ascent X 2.5.  This was A Blast to build! Amazingly versatile frame.  Built this one with a 4-Stack configuration! Includes a Runcam Mini FPV Onboard DVR in between Flight Controller and VTX. 

Video of step-by-step speed enhanced build is below.  Includes captions to highlight important things.    Please let me know what you like about this build and how you would personalize it for your own fun-flying!  Enjoy!

That's the Tightest build I have ever seen!.....
It's amazing that you managed to squeeze all that into such a small space.
You DID fill up every nook and cranny! Lol.
I'll be interested to see how she flies.....

Thanks! I know, right?! I am amazed at the versatility of this frame. 27-29mm of stack height space (depending on if you want to go to the bottom of the "roll cage" top or the top of it). I'm lowering stack height by at least another 1 mm by replacing 5 mm standoffs under FC with a 3 mm spacer and a washer (sort of a little soft mount). Doing this to see if I can put the 3D printed canopy from FlexRC on top (just because it looks cool!). I AM a little concerned that with this 4-board stack it may be a bit top heavy. I'm hoping LiPo will counterbalance it well. We'll see soon enough! Gotta configure in Betaflight (I have a couple "quirks" I'll need to do with that) and BLHeli (motors & ESC) next then take her out on her maiden. Those will be next 2 videos. Fingers crossed!
