This AOS build is the best sub 250g I've flown when compared to my 5". A bit better than my 3" vista build was. Great for freestyle. Not much else to say. If you want a sub 250g freestyle, this thing rips on 6s. AUW 247g Betaflight 4.4, Bluejay 18.1.

Ha, building the same, but with 1804, and 4s. mind sharing your cli, got the same GepRc 35amp, need the motors remapping. that flight controller is wacky inverted already. also GepRc said it was not good for 4.4, curious what you found that worms. thanks!
I just first flashed bluejay, now v19, (48 khz which is recommended by DJI for the O3) , then betaflight 4.4. I utilized the UAV Tech 3-4" preset on medium build quality with RPM filtering. Once you do this you'll need switch bidirectional dshot back on. I also used the 250hz ELRS preset. I've only got about 25 packs on it now. I need to do a little more refinement but it flies well. I'll message you my CLI.
I found that for freestyle hqprops dont have inaf pitch and with all up weight around 250g strugle to pull out of dive. Defently sugest to try gemfan hurricane 3525 and emax avan 35
i have the HQ T3.5x2.5x3 props also. i haven't felt like i have had any issues with torque on the 2" pitch and I feel like they have more grip. Murders flies 3016 on his 240g build. it doesn't look like he's struggling. i like Gemfan props also but they are considerably heavier. Now that I've removed the BEC I've got the room to pick up a gram in props.

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..

Have you had any issue with these motors? The shafts started spinning inside the bell on all 4 of my motors within about a week. I had a few normal crashes in grass and only one bell has a slight ding but I wouldn't expect the shaft to slip so easily.
interesting. I've had a few crashes but no real severe impacts yet. i have not experienced any issues with the motors. I've probably only got 25 packs on them. if i have issues I'll probably replace them with those 1804 rc inpower motors as they're just slightly heavier. I'm traveling for the next 3 weeks and the AOS is the only drone i took. fingers crossed.
