UPDATE: So sad to inform that I had the fatal 5v Crazybee F4 Pro regulator fail today. I plugged my 2s battery the FC failed. As per others observations, the FC has no problem with USB connection. This is a known issue with this FC when using xt30 and 18-20 guage wire. Sooo bummed!
Excited to share my Toothpick inspired 2s build! If you haven't been watching, Bob Roogi proposed a new ultralight class that uses the Beecore F4 AIO fligth controller and 1103/ 7500 motors. He's created a frame that is being replicated as everyone waits for the original to be available again on his site. (Kababfpv.com) The frame I used was created by, Alexandre Arvinte, a follower of Bob's and was posted on Thingverse. It's called the Pickle Frame and will serve me well until I can get my hands on the two Toothpick frames that I have on order with Bob. After flying it today, I'm convinced this will be a new class that manufacturers will start paying attention to. It's fantastic in all conditions. Even with a little wind today, it flew great.
It's a pretty straight-forward build that allows 4-5minutes of flight time with characteristics of a larger 4-5" aircraft. You can choose to lighten the load by removing the stock plastic motor connectors and hard wiring. Many are also installing a xt30 connector instead of the stock battery connectors that come with the board. Noticable difference in punch if you choose this path. It is a bit of a soldering challenge!
Once you have it all soldered up, you simply slide the FC and components onto the 20mm M2 screws and then insert the camera into the Beebrain camera holder. This is the best solution so far for this application. The battery and the motor leads are held in place by a rubber band that you wrap around the arms. It's one of those blue ones that you get when you buy produce. AUW is 40 grams with the Gemfan Flash 2540 props. The 350mah Tattu 2s batteries add another 30ish grams.
Final step is balancing props. These tri-blades are good however Bob recommends the KingKong 65mm double blades. I've yet to try them as I'm waiting for Bandgood to ship them..

hey is it because the gauge of the wire was too large or too small? Also Love your build!!! so cleann
Nice little quad! Is this a 110mm wheelbase frame like the toothpick? I can't find any information on the thingiverse page.
FPV has had quite a journey. Just a few years ago we started racing drones around a track and doing flips over trees, but professional cinematic FPV is a more recent development. DJI has always owned the drone photography market, but smaller acrobatic drones are starting to enter the market. They have the advantage of close proximity flight indoors and around people. There's more artistic freedom and..

With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..
