My second build (in the 200+-class). After i've built a very low-cost (but fun!) realacc x210 i felt like building something with (even) nicer parts. :) Since I was able to learn quite a bit about the basics during tinkering the realacc, I wanted to try to build it a bit more tidy this time.

nice build, out of interest what does it weigh?

Moxl Jun 10, 2017

Thanks! 380g without battery. Guess I could have saved a few g here and there, but I did not care too much about it.

Yea, I was just flying in insane wind with my action cam and largest battery and it was still fast though the wind was more of an issue than the weight to be honest

hey man, sick build! are you using the ppm or ibus on that flysky? im having such a hard time trying to connect my quad to sbus ( not really sure whether its the uart that im activating incorrectly on betaflight or the solder point that i connected it too) i have it on ppm as of now but i can tell theres a big difference in the flight characteristic. if you can help me out that would be great!

Moxl Jun 06, 2017

Thanks, mate! I had problems getting ibus to work on that particular fc, too. The reason was that the port that is labeled as ppm/sbus is harware-inverted which is bad for ibus. Thus, i did not use the pins on the half of the fc where the motor signal wires are located but the uart pins on the other side. This video explains it pretty clearly:

Afterwards you simply have to set uart1 to serial rx in betaflight. Hope that helps :)

Jun 21, 2021

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..

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..
