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
