At this point, it's safe to say my favorite micro of all time is the Babytooth 3". I've built at least 10 and they all have that super sweet power to weight ratio that put the Toothpick on the map as a micro class. I took advantage of a few free days over the holidays to build this one with the new TUNERC 1-2s board and FPVcycle 13m Light (11400kV) motors. If I'm counting correctly, this is the 4th version of the 1s board and the 2nd iteration of boards with TUNERC. This board is back to a traditional whoop square board which provides a bit more real estate for place your RX and VTX. It's also a few grams heavier than the previous 'X' or cross shaped board so that should be considered. I decided to flip the board upside down as I like to solder my motors under the board and that turned out fine considering the through-hole design for both the RX and VTX connection points. With the flipped board, I had to reroute the motor resources and flip the gyro sensors in Betaflight. All very easy to do. As for the frame, I used a custom 2mm frame that my friend FaebuFPV designed and had it cut by Nick at CNCMadness. It was roughly $15 to cut and included chamfered edges which I really like. I also lightly sanded the edges and use a Q-tip dipped in CA and run it around the edges for a glossy smooth & clean look. The RX & VTX are both TBS and are wired using the Crossfire protocol that allows the system to be controlled by the TBS Agent Lite on my TBS Mambo. It's a little extra wiring and not 100% necessary but the TBS ecosystem is super slick and has ongoing updates. The camera is the FPVcycle Caddix Ant Lite that has been my go-to since lanch a year ago.

I'm very happy with the end result. Although it weighs a few grams more than my daily Babytooth flyer, it performs great with the new board and motors! Special shout-out to Bob Roogi (FPVCycle), Raphael Pirker (TBS), and Aria Chen (TUNERC) for pushing the FPV hobby forward!

Please feel free to hit me up with any questions.

Thank you! Flies like a dream.

Any chance you still have the frame files? I've been meaning to make a babytooth frame with a USB slot and that exactly what i was thinking of. Great build, i can't think of a single thing I'd change.

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..
