Still waiting on parts to complete my Kylin. The frame is assembled, so I just need to slap it all in there. I'm debating using the LEDs in the back or not, since now I'm thinking about a "murdered out" look and going all black thanks to a screwed up order by helidirect. I had ordered a blue cased Foxeer Night Wolf v.2 but got black instead. I have a bunch of older ESCs and motors I can slap in there just to get it flying while my permanent motors and ESCs arrive.

Notice from the pic below I'm giving soft-mounted motors a try. I'm using silicon Rescue Tap on the top and bottom motor mount surface of the arm. The motor will sit on the top surface. I made some plastic disks by cutting up a clear plastic disposable dinner plate. The screws will go through the plate, to lightly compress against the bottom layer of silicone, while drawing the motors lightly onto to top layer of silicon. The FC will be mounted on those standard rubber isolating 3mm mounts.

Speaking of FC, this AIO FC should make for a SUPER clean build. No external PDB, no external OSD, no external VTX. Smooooth.

Parts list:
-Realacc X210 Pro 4mm 3k carbon frame
-HGLRC F4 V5Pro FC with integrated VTX, OSD, PDB, BEC running BF 3.1.6
-Frsky XSR SBUS receiver
-Foxeer Night Wolf V3 IR sensitive camera
-RCX RS2206 2400kv V3 motors
-XRotor 30A ESCs
-King Kong 5x4x3 props

Temp parts:
-"Emax" MT2204 2300kv motors
-DYS 16A ESCs

I'm somewhat disappointed with this microquad. It looks great, if I do say so myself, but it's in need of some serious tuning that not even BF 3.1.6 stock PIDs can fix. It could also use some 65mm props instead of the Ladybirds that I have on there. I'm guessing one of the motors or props is out of balance and causing some serious vibration. I'm also running the AKK Technology BS2 cam/VTX power wires loosely across the FC to the battery pads so maybe they're banging around on the FC too. Anyways, it still flies, but will need some work. The frame certainly feels sturdy though, so it has that going for it.

Parts list:
-"DIY Micro FPV RC 100mm" carbon fiber frame from banggood
-Racerstar 8520 coreless motors (direct-soldered)
-Ladybird props
-FRF3_EVO_Brushed FC running BF 3.1.6 with integrated Frsky SBUS receiver
-AKK Technology BS2 AIO cam/VTX

So far, this QX95 is my best flying brushed micro. How's that for an opening statement? It's even on the stock Cleanflight 1.13 firmware that came on it. Thanks to a little diet to lose some weight (ditched the upper plate and stand-offs), and some beefier Racerstar 8520 brushed motors, this thing now really moves! The power to weight ratio is incredible for the size.

I was so confident in how I'm able to fly this craft, that I even attempted to do some cliff diving with it, but it ended in an epic fail due to two failsafes and two difficult walks-of-shame because of the steep mountain terrain while wearing flip-flops. It was a spur of the moment thing. The first failsafe was due to the location in the air that I had parked it, to line it up for the dive. It was behind and above me, so my radio that was in my lap had to go through me, as well as the FC due to where my antenna was pointed. I'm sure some boulders were probably in the way as well. I say "was pointed" because this crash ripped off my antenna, which I failed to notice before my second attempt. That explains the second failsafe, which happened about 30ft from the cliff edge that I was standing on, and resulted in a 100ft free fall.

Parts List:
-eachine QX95 frame (this is my third replacement frame)
-FRF3_EVO_Brushed FC (de-socketed) with integrated Frsky SBUS receiver running CF 1.13
-Racerstar 8520 coreless motors (black) direct soldered
-Ladybird props
-AKK Technology A3 AIO cam/VTX with selectable power

I had some spare parts laying around due to a destroyed Eachine QX90C frame, so I figured I'd cobble together something cheap and tough; something that I can let my friends and neighbors fly around and crash into things without any worries. But it still had to be fun and cool. A quick trip to thingiverse yielded this 90mm frame created by dschiedsch.

I took some liberties with the plans. I skipped on the battery tray, and opted for Velcro to hold the 600mah 1S lipo to the undercarriage. Rather than bending the camera platform down to attach the AIO VTX/Cam as per the instructions, I kept the shelf and adhered the cam using hot glue. After printing the main frame out of bright green ABS, I started the print for a second frame, except I stopped the print after the main body was finished (before the motor supports started to rise up out of the print). After reaming out the motor holes in the second lower profile frame, due to the stop-notch that's built into the motor mounts to keep them from falling straight through, I now had a dual-level micro frame that would always keep the motors perfectly square and upright, and has so far proven to be my most durable FPV. And as a bonus: it practically glows in the dark, just from the FC's LEDs shining through the ABS.

Parts list:
-3D printed ABS frame (see above)
-8520 motors from an eachine QX90C (direct soldered)
-eachine FRF3_EVO_BRUSHED FC from the same QX90C (de-socketted) with built-in Frsky SBUS receiver
-eachine TX03 AIO cam with switchable power VTX
-Ladybird props
-micro buzzer
