Fractal 75 1s

*Update on 4/2 I moved the thicker frame (carbon fiber portion) to a 2s Fractal 75 I am building and put the thinner stock frame back in and lost 0.6 grams. of weight. Now weighing 24.9g.

Once I saw this frame I had to have it. Started with the 65mm and now have two 75mm frames. This one will be 1s, the 2nd will be 2s. Please notice that this is a whoop in compressed X layout.

JHEMCU GSF405 FC is, in my opinion, the best whoop FC currently. At 3.3 grams with built in ELRS I would still favor this over the new blheli32 - T-motor FC. Paired it with HGLRC 0802 at 25k kv and an TBS unify nano pro 32 VTX and thats about it. The fractal frames have option to come with or without whoop frame (cut it up). We cut the frame into pieces and attach to the carbon baseplate. Creative TPU usage to boot. Whoops suffer from huge frame vibrations. On a 411cpu with rpm filtering its like flying a turd on most flight controllers. The 405 CPU is much better than 411 and this frame makes a good pairing as there is very little plastic to vibrate. The sacrificed whoop frame was a flywoo and is stiffer than anything from house BetaFPV. Fractal offers thicker carbon as well and this frame is the thicker option. I may have to move this carbon to th 2s when I build it and move the thinner carbon to this quad, we'll see.

Durability... I have a bag with about 6 broken newbeedrone "extremely durable" frames. I have yet to damage a Fractal quad. I like to fly fast around close proximity objects. I was pit crew for my brother when he was in a racing club and always I wanted to go fast too. Got injured to the point of not doing anything physical again so I fly quads to get my speed on. I do laps around my yard after work to forget about the work day. Lots of metal. Light pole, railings, etc. This frame just bounces off metal when impacted. Its remarkble. Activate crash recovey in betaflight and its like never hitting the ground..

Fractal gives us short screws as they designed this to be around the happymodel diamond 411fc but mounted upside down making the odddly placed usb accessible. Really wanted the F405 so I drilled out the holes larger and sent glass filled nylon screws up from the bottom to mount the FC and then layer a TBS toothpick mounting board. on top. Tying off the antenna keeps it stable. Camera is a runcam nano3 and not much else will fit. I have a caddx ant light ready for the 2s that will be posted next. Cant fit a ratel nano. Could but it would be aimed parralel with the frame as the front flight controller mounting screw restricts the camera angle. Thinner the camera is the more angle you will get. Its the only negative attribute about this frame that I can mention. Running bluejay firmware of course. Added BT2.0 and it really makes a difference with the motors. I dont like to go more than 30 some percent on batteries, a 450 would be too heavy and not as fun. 300mah is perfect. On fractals site they offer STL and step files of their TPU. Within is a double decker battery holder inviting the 2s thought. Best 75mm I have buit yet or the most fun to fly.

DVR looks like HDzero.
Is it really analog?

Having a hand to face moment, thank you for asking. I was on hdzero last year with a VRX on the front of my skyzone04x. I'm injured and the added weight was too much on my neck (compressed disks touching nerve cortex's). Combined with the other nuances (low quality hardware and cheap cables) I tapped out off hdzero and sold it all. Was on dji the year before and have gone back to analog for this year. It was nice but cant justify the $$ for the state of the technology. I really need to upload new vids, apologies for not catching on your first inquiry. Rain for the next few days. Will have new vid uploaded for Fri or Sat.

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..
