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 !!!

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!

mascaras Oct 04, 2017

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

mascaras Oct 04, 2017

thanks ROB and also thanks for the tips/help !

Jun 21, 2021

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..

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

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..
