This is my daily flyer.
Custom sub-50g freestyle micro, designed to replicate a 5" top mounted battery layout and flight characteristics.
Best flown with a 350-400mah 2S Battery due to space limitations. Anything bigger has to be underslung and retuned.
Frame designed for 1103 - 1106 motors (8.5-9mm mounting pattern).
Requires 4x 15mm nylon standoffs & 8x 6mm m3 nylon bolts.
Supports up to 3" props (with alternative 3D Printed pod design). 2.5" (65mm) prop size max with carbon canopy.
Femto FC mounted with foam tape, but the frame supports 16-20mm FC standoffs as well as standard 30.5mm for the lols.
Motors are soft mounted with bicycle inner tube rubber. Same material used for the battery slip pad.
RX and VTX antennas are custom cut from 1.13mm IPEX coax cable, routed through the plastic straw from behind the LED panel to route them away from the carbon cage.
Range could be greatly improved with an XM+ receiver. Then 2.4 will outrange the video on a 25mW whip VTX, but there's no space for a CP.
Betaflight PIDs for acro tune
350mah 67g AUW. Every gram affects the tune at this scale.

Awesome job! That frame is sick!! Watching the vid, I was sure you were going to smack the ground going over that first tall pine tree...totally pulled it off though.
Hey if you can, can i give you drawings with measurements and can you turn them into a frame? im very desperate now because i cannot find the perfect frame. I needs to be lightwieght but also top mounted. I need help huhuhu
What do you mean? Turn a pencil drawing into CAD? Or you have a CAD drawing you need cut? You can get your CAD cut with http://armattanproductions.com/ (I used them they're amazing). I wouldn't really consider making a CAD drawing for you because it takes quite a bit of time plus a few prototype runs to get everything right, so without charging for all the R&D I can't, sorry!
do you have the files for the frame?? i reallyliek the design and i want to use it for my prototype im working on~
Hey i got a tip for you, if you buy new motors for this quad get 1103 8000kv. It works realllyyy well with the gemfan 2.5" flash props!! gonna post a build in a few days about it!
do those props make the quad more drifty? i mean like in sharp turns...does it drfit and take more effort to take a sharp turn or its easy to make a sharp turn around something like a tree?
It's not bad in windless conitions! I have a video from dvr here https://youtu.be/j0jTkHa0GJA?t=229 at 3:49-4:09.
Do you have any fpv vids? Really nice build
Hi there, just saw your build in Flight Club Auckland. I'm there too but haven't raced yet. I have a couple micro builds both on here, sing out if you get caught short on parts etc. Love that frame, did you design yourself?
I live in the city, so Mayers and Albert parks are my only option, except for maybe some urban spots where nobody is around on weekends. Can only mostly fly on Saturdays or early mornings before work.
BTW You can't fly in Cornwall without permission because it's private land, not council controlled.
Keen to fly together some time!
ERMAHGERD TOO CUTE. seriously ... it's very cool ... not trolling :)
I bet it rips, too. My 65mm build is like 10g heavier and runs 6500kv 1103's and is a blast. Flies for like 7.5min on 450mah 2s.
Nice build! I wish there was a circular polarized solution that's smaller than a clover or even AXII for these tiny builds. If you go with a whip, you can loose all that canopy. Also cutting down your motor wires will loose you a gram or so, so will those zip ties, don't need the RX antennas that long :)
I'm keen on a micro foxeer that was just announced.
Ok. Mine seriously has to lose weight. It is nearly twice the weight of yours, at it's lowest it was 88gm and only runs 2" props. Like I said, needs work.
I also like the battery on top idea. I am having some serious tuning issues coming out of dives or fast forward flight. I think battery on top may help! Thanks.
Looks great! Are you selling the frame?
I like the back of it, mainly because how parts from completely different places have just fit together so well (the hole in the LED board is perfect size for the antenna protector straw) plus I love LEDs, but I see what you mean, I changed it to something that makes more sense, thanks for the suggestion!
Guides & Reviews
AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

haha thanks bro! I've been out of quad game for a while. You think quads are an expensive hobby? I got into sailboats... lol.
Appreciate the support!
