This is my X-Class "Beast". I built it a year ago with analog technology. Back then I scrapped it because of VTX problems. Half a year ago I converted it to the DJi Fpv system. Building such a drone takes a lot of time and money. You have to learn to solder such thick cables before trying it on a $ 99 ESC.
I shortened the frame by 4 cm per arm because it just looked nicer and it is still huge. The frame is completely foiled. I designed a lot of print parts. I installed the Brain FPV Radix Fc because it is simply the best for such drones. But if you take the 12v from the APD PDB500 you often get OSD problems. In the video I still fly like that and it was the first flight after the conversion .. the pids weren't great either and the video doesn't show the potential of such a drone. Today the thing flies really well and I run the dji Air Unit with a separate 4s 850mah Lipo.
Such a drone is not suitable for everyone. With such a drone you can kill yourself or other people. So such a part has to be done with a lot of respect. When flying there are 1 meter drone with 12s, 50v and 500 amps in the air. With an insane speed and 4500 grams flight weight. So always fly with a spotter and think carefully about what you are doing. If you consider all of this, I can only say: Flying an X-class like this is the best I've flown so far. I was unable to include the motor link in the price calculation below. You then have to add 460 euros for four engines. Are currently available at Banggood in 360KV. Greets

Great build sir! I am converting one now myself from analog to DJI. any chance you can share where you found the prints for the xt30 for the air unit. as well as gopro holder and gps. if they are your prints. can I pay you for the STL's by chance I did not see them on your Thingiverse profile or anywhere on Thingiverse for the source x with those prints.

BEAST....look how tiny the GoPro looks on this thing?!?!?

The Batterie Strap in the bck its for an extra Lipo for the DJi Unit to power it up. The 12 v from the PDB make often Problems and you have OSD problems. I asked Catalyst Maschineworks and they told me that they heard much time from that. The Idea with an extra Lipo comes from the nice guys of Catalyst. Its worked fine

i have an idea as to why you have a battery strap towards the rear, but can you confirm what all of that is used for?

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..
