This is my first toothpick build, never been a fan of the undermount battery design. However, flew this on the weekend and I like it..... I fly with 520 mah and 820 mah 1s batteries.

Specs:
Dry weight: ~50 grams

Things to do:

  • Not quite happy with the capacitor mount want to see if I can remove it without impact or see if I can improve the design
  • Need to see if I can get a buzzer on the drone.

The Bitmatta brothers, Paul and Thomas, are racing icons on a global scale. They have put in countless hours perfecting this frame to suit their demands after years of racing at the top levels all over the world. google

remove thoses ugly skids and the capacitor, you'll loose a bit of weight, the build is cool tho!

This is an immaculate design/build!
I bet it flys amazing. I dig the look of the skids, and the overall vibe is athletic.
I am afraid for your Rx antenna!! I see the multilayer heatshrink job, and I want it to work, it looks so good.

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..
