AOS 3.5- Sub 250g ripper
By CloslaRoche on Oct 14, 2021
Disc loading is a weird thing. On one end, you have incredibly floaty quads with zero fling and instant response. On the other, you have really really heavy flying cannonballs that fling for miles from one throttle blip. By the math, 3.5" Has about the same disc loading as lighter 5" quads.
And I have to say, this is probably the best flying quad I have built. Its incredibly responsive, it has some fling but it has enough grip in the air to do complex moves very close to objects without washing out or drifting. The 16mm motors from Bob Roogi/ FPVCycle are perfect for swinging a 3.5" prop and are lighter than I expected.

Very cool! I have an AOS 3.5 on order and already have the FPVCycle 16mm motors. I wasnt sure I would use ghem in the AOS frame but after reading your comments, its for certain! ill probably use a Flywoo F7 EVO AIO that I have but might also use a Radix. Ill have it finished the day the frame arrives and really looking forward to it now!
I have posted my build which points to yours by the way.
Thanks again!

Hi there! Thank you for the inspiration :)
I would like to build the same, but with DJI nebula pro nano.
Do you know how these motors (including prop and nut) compare in terms of weight versus TOKA 1505 for instance?
I am really hesitating between those 2 motors, but I really would like to keep the dry weight below 174g to run it with R-Line 750mAh
I know, the kit comes with a small adaptator, the quality between the nano and the pro are very similar.
Thank you very very much for the rapid feedback. I know the fpv cycle are 3mm shaft so you can't use the Avant 3.5 prop "out of the box" but may consider drill the middle hole to make it work... thanks again, FPV cycle is a go :)

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..

Beautiful build!
What seems to be the max flight time, when cruising?
I already have a TP3 and recently built my first full size quad, the AOS 5.5 of which i will also post here.
Cheers from Germany
I don't know to be honest, never did a real "cruising" flight. However I used it as a cinewhoop recently and on the GNB 500s I could do a solid 8min of following/ orbiting flight.
