This was inspired by FPV cycle Baby tooth 1S.
Unfortunately, I was not able to source the FPV cycle parts. I had to find something to replace them.
I have been using CrazyBeeX v2.2 FC. The VTX and one of the ESCs have died. Now I have switched to the CrazyBee F4 Lite. Since this FC also had fried VTX, I have used HappyModel description to connect the external VTX to it. Described here: http://www.happymodel.cn/index.php/2021/01/23/how-to-add-external-vtx-for-crazybeef4-lite/.
I had to add the inductor (10uH) between the +5V line on the FC and the TBS Unify 32PRO nano VTX. The cammera is powered from the VTX passthough pins. Video signal and Smart Audio are connected directly to the FC. Without the inductor I had terrible video noise and screen rolls. Now it's flyable with minimal noise.
This FC have problem powering the VTX when set to more than 100mW output power. It will brownout during the flight. When you will switch back to 25mW or 100mmW everything is back to normal.
Whole drone weight is 49g without the battery.
I have rebuilded this quad in new version. GRI BabyTooth v2
sweet!
for 1S you can loose the prop bolts and save a gram or two.
I run 2s with no bolts for that reason :)
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..

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..

Did you have to flip FC upside down or kept it as it is? The reason why I am asking is that I've got the same Apro 125 frame, Flywoo motors, Ant Lite camera, etc. to create a babytooth my own but do not have the BeeBrain canopy that everybody uses, and I wonder how I can set it up to have USB port access...
Yes, I had to flip the FC. Unfortunately I have to take the canopy off to access to the USB. Now I'm using the FEICHAO canopy. I find it most durable of all tested. I have tried the mobula 6, modula 7, Eachine Cinefun, Eachine Canopy for UZ65 and the Happymodel Crux3 canopy. They are all very fragile. I have ended breaking them every 2 days. Happymodel Crux3 is second toughest I have used. You can cut off back side of it and then you will have access to the USB port.
