The Lumenier Piko is a pretty nice 2" setup with a very adaptable camera mounting design. Weight with no battery is 80g, somewhat heavy for a nano/micro with 2" props, but it definitely feels fast in the air. It handles like a larger quad, perhaps due to the ~120g (auw) prop loading, but it's still extremely capable. So far flight times are around 3-5 minutes.
The Spedix ESC listed here has M2 hardware mounting, and I drilled it out to M3 to fit this frame - however after finishing the build with steel bolts rather than the included plastic hardware, it failed the final continuity check (always check a new build! it saved my components here!), obviously from the ESC PCB layers shorting out on the hardware. The plastic hardware eleminated this issue, if I were going to build it again I would definitely opt for a 20x20 4IO ESC that used M3.
The camera mount simply uses a thin rubber stick-on layer on both sides of the mount and sandwiches any 19mm wide camera, whether it be most micro cameras or the AKK AIO SA cam I used here. I have confirmed myself that a Predator Micro and a Caddx SDR1 Micro will also fit, but you would need a piggyback-style VTx right behind it as well.
Overall, I love this tiny quad, I fly it often because it's so simple and quick to get in the air. Betaflight 3.4 defaults work great and DVR on the goggles still allow for some recorded flights. It's very peppy and definitely likes a steep camera angle.

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..

Hello Etolier,
Thank you for sharing this great quad!
I have some questions please if you don't mind, as there are no reviews for this frame and it is not even referenced on the Lumenier website... (weird)
So, I am in the process of choosing my parts (for a piko 3", its my first build, I guess I might need the 3mm plate despite the additional 4g) and I need advice please.
I chose a 20x20 4IO ESC as you recommend : XRotor Nano 20A 4in1

But you lost me with the M2/M3 screws problem. Is this frame for M2 or M3 parts?
I am now afraid that I will not be able to mount these parts with this frame... :/
Thank you again,
Ericno
Hi Ericno, this particular frame uses M3 hardware, and since the FC and ESC boards need to be fitted to those same M3 structural bolts, I had to mill out my Spedix ESC (it was designed for M2 mounting hardware, and not ideal for structural stack frames like the Piko 2", so I had to modify it). If that XRotor Nano uses M3 mounting holes then you should have no issues, but I would still encourage you to do a continuity check with a multimeter to determine if the conductive material that contacts the mounting hardware is battery positive or ground, as some components can use either in their design. For example, after milling out the mounting for my ESC, I found that the board would short out battery positive to ground on the FC board if I used metal hardware through the stack. Checking with a multimeter first allowed me to save shorting out my components and damaging them - I switched to plastic hardware before powering it on for the first time and had no issues thanks to that continuity check.
I tried to research your XRotor Nano stack that you linked, but it seems like the manufactuer doesn't provide details on whether it is M2 or M3. It looks like M3 according to the pictures, so I think it will be a good stack for you to use with this frame. I hope it goes really well for you! Don't hesitate to ask me anything else, I was surprised by the lack of information on the QAV-Piko frames, I would be glad to take a close look at anything on mine for you.
