new 4 inch super light racer (sub 250g)

The Ori 4in1 25A ESCs from Airbot Shop fits this frame but i had to install them with XT60 on the front side of frame and with xt60 cables coming to the back , because other way (correct way) the 8 pin cable that connects ESC to FC wont let the fpv camera fit ( it also fits using the ESCs with XT60 on the left/right side of the frame but the FC USB will face the front or Back of the frame so i opted to install them with XT60 coming from the front of frame , you can check the Photos)

Runcam micro & VTX are both connected to Omnibus f4 nano v3 BEC (5v) no problems at all , great FC !!

These Ori 4in1 25A ESC from Airbot Shop are great , no problems so far with 4045 dual blade props and tornado 1407-3600kv , and by the way im not using any External capacitors .

AUW = 138g (without lipo)
AUW = 248g with tattu 850mah 4S 75C

Im using betaflight 3.2 , Dshot600 ,dynamic filter PT1 on omnibus F4 nano V3 and Blheli 16.63 on Ori 25A 4in1 ESCs (Soooo SMOOTH )

maiden done and i love this racer , these brotherHobby Tornado 1407-3600kv are so good !!!

3S Lipo

nice job! and a great auw too!

If you can be bothered to swap your lipos to xt30s and shorten the battery leads too you can easily shave another 4-5g

That 4in1 looks fancy, hope it fits ok!

thanks , and congrats on the Nice frame :)

yep Xt30 is lighter but i used the new XT60U its only 2g (XT60 = 3/4g ----- XT60U = 2g --- XT30 = 1g )
the ori 4in1 25A fits in the frame but i had to install them with XT60 on the front side of frame with xt60 cables coming to the back , because other way the 8 pin cable that connects ESC to FC wont let the fpv camera fit ( it also fits using the ESCs with XT60 on the left/right side of the frame but the FC USB will face the front or Back of the frame so i opted to install them with XT60 coming from the front of frame)

I updated the Photos showing how i install the ESCs.

Cheers! and thats sweet I had never seen an xt60u before, decent weight if it handles the same current as a regular xt60

Edit: that esc is tight! good job making it all fit, its a challenging build but I wanted this frame as small as possible to be as light as possible

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..
