Worlds lightest 2.5 inch 2s quad

By Derk on Sep 01, 2018

4 387 3

I built this because I wanted something that performed better than my old brushed micro quad, but I also wanted it to be lighter. I made up some 3d printed adaptors for the motors, and the 16mm x 16mm flight stack. The end result was a quad that is significantly lighter and more powerful, at 53.3g including the 2s lipo!

did you happen to still have the 3d printer flies for the brushless adapters? have one of these frames lying around, figuring out what board to mount with my old flysky transmitter.

i have this frame for brushed quad as well, not so long ago, 3 months or so. i've used it to learn fpv. i've had great time with it. nothing like first time flying fpv :). i'm still using it to practice flying line of sight, because i still have many spare parts left. did you try it with 2s batteries ? it's really fast. anyway, i'm going to convert one of this frame to brushless build too. because i can't find frame that uses kk 65mm props and 08xx motors for 1s build.
anyway, onto brushless now.
your build should fit this frame nicely.

Very creative with the 2x 1S batteries, tapping into a readily available power format, there! At that weight I'm sure it rips. Radical.

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..

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

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..
