Update 7/16/2019:
Added Eskimo hood on camera held on with small rubber band.  Wrapped arms with silicone tape, sealed ends with ring of UV cure adhesive to keep from peeling back.  Swapped linear antenna for circular polarized, supported by foam and UV cure adhesive to maintain angle.  Added o-rings to camera screws for better camera angle retention.  Setup global variables on X-lite to put compensated throttle curve adjustment on a slider, (helpful in finding what works best, I'm no expert but I recommend recording the values you like and setup a switch for 2 or 3 configurations depending on flight style).  Throttle cut for basement flying tonight.  The new AUW with 2S 450mah is about 76 grams.

Update 6/21/2019:
Changed to 2S 450mah battery and back to 65mm props.  8 minutes of hot laps in the basement moving pretty quick and around 40% throttle, battery was down to 3.65v per cell.  I like the responsiveness and punch of 3S, but these motors just can't handle what I want to do with them.  I'm downgrading this to 2S for now.

Update 6/16/2019: Complete rebuild, 10 grams heavier and better range.  V080x frame, 2-4S 12A iFlight Succex Micro F4 Stack, 9000kv motors, XM+ Receiver, Eos2 camera, Azure 2.5x4x3 props.  6-1/2 minute cruising basement flight.  VTX does get hotter than most, performs ok so far.  Camera mounting with a stack needs to be revisited. Flight is smooth and quiet, never needed more than 40% throttle indoors. Should get it out later this week.

Update 5/28/2019: Trying the sailfly-x props, flew 8 minutes, cells ended at 3.6v each. Good control. They have a less parabolic leading edge and rougher surface finish than the Kingkong 65mm props. And I noticed the edges are flat instead of sharp. I'm going to use them as beater props.

Update 5/27/2019: So after shredding my props on the coffee table, I didn't fly this one for a while. Plugging it in today, no Betaflight... After 20 minutes, discovered that the boot button was depressed against the frame. Added soft mounts under FC, and had to change the battery settings back from defaults of 1v max per cell. Weird. But after remounting FC, had a 9+ minute basement flight that got me smiling again. Batteries were down to 3.3v per cell tho.

This is the blending of a 3S whoop powertrain with a toothpick style ultralite. Probably best served as a tiny backyard racer.
I found the camera mount for the Mobula camera to be a hassle. I would recommend the Caddx Eos2 (edit: RunCam Racer Nano, plus new mount) instead, frame kit includes a nice Eos2 mount. Trashcan VTX mounts with a separate accessory, designed to go along with kit. 7700kv a must for 3S on Happymodel F4Pro V2.0. (edit: 9000kv for GEPRC/BetaFPV AIO 2-4s FC).
A bit of tiny soldering required to land camera wires on FC board. The canopy is really nice and has multiple areas to run antennas out of. I zip-tied the power leads to the arm to keep them out of the props. Then wrapped the arms with silicone self-fusing tape to protect receiver whip and motor wires. (I include a link below for what it looks like, just buy from hardware store).
Weight all-in with battery was 62 grams, lose the silicone tape and it was just shy of 60.
Maiden flight last night in basement due to wet conditions. Battery charged to 4.1V per cell, cruised around in stability mode for just shy of 5 minutes. Everything came down cool, just VTX was a bit warmish. Typical amp draw around 1.5A. Good throttle response, but had to limit short punchouts to 2.5A to keep from smashing thru the ceiling. Plenty of power, my instant favorite micro. Will try some ACRO outside when the yard dries up.
I left default PIDs on FC.

Update 5/5/19: Cruising basement speeds on 3s charged to 4.2v per cell, 300mah. 8 minute flight, cells each around 3.7v. Motors just a tad warmer than room temp.
Another 3s 300mah lipo charged the same, performed a whole bunch of mini-basement punchouts, 2.5 amp max. 5 minute flight, cells each around 3.9v. Hit ceiling, canopy absorbed it, protecting camera. Everything still looks mint.

Do not attempt to wear shorts when operating this vehicle. Pajamas are pre-approved for morning flights only. Some peak amperage limitations may apply. Consult your local guru about 12amp service, 200mw VTX, and full range receiver.
