CrzyX²

The story behind the build

After I build the CrzyX I tried to tune it, but I reached the boarder very soon - in my opinion the arms of this frame are to weak, at least for the higher weight of an digital build.
During a testflight the copter dropped to the ground (soft meadow) from less than 10 m and two arms broke. That was the moment I decided to mod this frame.
And yes, it dropped due to an accidental disarm... :)

Choice of components

The components are more or less identical to the CrzyX. I just used a second set of arms to reinfore the frame added a Mamba interference shielding and changed the capacitors. It was an 2-month odyssey to get the arms from Armattan Productions, but it wasn't their fault and they provided perfect support!

Building

It was more a modification than a new build, but amazingly everything fits together, like it was meant this way.

Flight quality

I changed the props to 4.8" what meets the motor characteristic much better. Now the voltage drops are in a normal range and the copter still has more than enough power. Due to the small weight it feels extremely agile and the accerleration is just sick.
With the rigid frame, I can reduce the filters to a minimum of one single D-term filter with RPM-filtering and a Yaw LPF, pushing the master multiplier to 1.7...and it's not at the edge yet.

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..
