My attempt to make a super light, public save 2S outdoor "Whoop" with the almighty 65mm props ^^
Guys, this thing is so much fun!
UPDATE
The BeeCore board stopped working after one week. Now it's only starting with a 1S battery or USB. With a 2S pack it don't turn on at all.
I'm waiting for new parts which will probably take 2 weeks... Missing to fly that thing already.
Version 2 will get a decent nano VTX and definitely a better camera!
AUW: 61g
I'm currently using a modified 95mm RJXHobby frame.

Motors are HBFPV 1103 11000KV motors

Very unhappy with the picture quality of the Caddx Beetle AIO cam... The light handling is really bad.
Someone know a nano sized cam with decent picture quality? Please let me know!
Here a video of the maiden flight.
Follow me on YT if you want to see updates on this little thing!
Thanks!

I'm sorry for the issues with the Beecore. I'm sure I'll find it has issues too. That is also too nice of a build for those motors! Looks super fun
I've got the Caddx Firefly (cam + vtx combo) on a micro build and the video is fantastic. Handles flat light/low contrast conditions and light/dark transitions very well.
Looks sweet dude!! id probably follow this for my next build. You should try the Caddx Eos2 maybe. Its decent and light handling isnt that bad. And I think its as small as a nano camera. Anyways, great build!!
The problem is most of the 1104 motors are made to run on 3S.
Nearly all of them are between 5000 and 7500KV which is probably a bit low for 2S.
In addition they are much heavier. The T-Motor F10 for example are 6g which is double the weight of the 1103 motors I use right now.
Unfortunately all I have right now are 2045 four blade and 2840 tri blade props. I don't think the 2840 will fit but I will try tomorrow.
itll be interesting to see what you find but i doubt that 1103 can effeciently and smoothly spin a 2.8 triblade hahaha. you know someone should make a vtx backpack for the Eos2. Its a great camera for these tiny things and yet ive not yet seen any 3d printed mount that fits a vtx and the cam together while being able to use the mounting holes. That would have been cool hahaha
The AKK AIO cam from RDQ was decent IMO.
Very cool! I'm following on here and YT now. I've been curious to revisit this type of build with the new brushless stuff instead of 8520. What kind of flight times you getting? Have you tried "long range" with it? :D
Thanks a lot!
Freestyle like in the maiden flight video about 4:30
Cruising will get me 8 minutes flight time with the Infinity 450mah batteries. It's insane!
I finished the build yesterday so I can't say much about the range but I don't expect much from the 25mw VTX on the Caddx cam. We will see, I will do a range test and upload a video this weekend.
They are fun, aren't they?
I have an Eachine US65 camera/vtx on mine and I am also very unhappy with the camera (which I believe KababFPV lists as one of the better cams).
How did you mount an R9 antenna on this little frame? It's not always easy to do it on a 3" drone!
I raised the FC just as much so the R9MM is fitting underneath. I use the stock antenna which is coming with the R9MM. I routed the wire under the arms. As seen on the picture they are a little longer than the arms and stick out a bit. They can't get into the props though.
I know beneath the carbon is not the perfect place for the antenna but there is no other way I can think of.
I really like the 3D printed mount for the FC on yours! This is such a good idea.
My frame also only have holes for 16 and 20mm stacks like the Lil' Duece.
I have a Caddx Eos2 but it's nearly 4g without the VTX.
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..

How did you wire the beetle for betaflight osd?
You need to separate the last pin on the side with the 3 pins and solder a wire on both ends. One on the camera boad and on the VTX board. Those wires you solder to the Vin and Vout pads on your FC.
