Thank you very much for sharing.
I also bought an ATLAS frame and I intend to reuse my old xing 1404 3800Kv as well as a succex-e FC and the O3 of course.
I looked at the 3D files but I don't understand how to print the big part of the antenna mount, it needs support?
Will you share the front antenna TPU mount soon?
Another question about O3, is it installed with the elements of the original kit or do we need to manufacture/purchase others?
Thank you.

Sorry for the late reply, I already uploaded the two print files(Antenna Mount and and TBS RX Mount ).
Link address:https://www.printables.com/model/946807-flyfish-atlas4-folding-antennaxt30-mount-geprc-m10
In addition, in order to space for the power cable, the O3 unit requires additional nylon spacers.

Great write-up! Looks like a fun combo.

Hi, would there be a link to the antenna holder like ours in the front under the camera. Thanks.

I greatly appreciate the time and work you have put into conveying this critical knowledge to me. play driving directions game

The folding antenna mount is so smart !!!!! I'm going to do something similar on my builds ! I can't believed I didn't thought about it by myself because it's always a paint in the b.t to have the antenna that sticks out during transport. Thank you for the inspiration, I'll post shortly my revised build with a folding mount as well !

One of the cleanest long range 4" builds I've ever seen. I want to say one of the cleanest long range builds of all time, but those are deep waters. Some of the long range 7"& 8" builds on this site are out of this world. While they are vastly more expensive, and some would say that's more impressive, I tend to lean the other way. I think that getting the same kind of range with cheaper batteries/motors/frame is in keeping with the efficiency minded aspect of long range.
I do wonder if the larger rigs have a cruising speed advantage, leading to a higher top end range possibility, do 4" rigs go as far as 5" or 8"? I have a 4" freestyle rig and it is VERY fast, so I'm very curious. I don't really know numbers for cruising speed for the different prop sizes.
Your xt-30/folding antenna mount is 10/10. Excellent part choices, and your wire management looks great!

Thanks,Matching the motor and propeller is a science, a process of trial and error.
So I borrowed the configuration from Geprc Tern LR40.By the way,LR40 uses a 2-blade propeller(HQ 4X1.9X2),It is true that two-blade propellers have longer time than three(HQ 4X2X3).I think advantage of 5" or 8" Drone lies in wind resistance and larger range.The size of the drone you choose depends on your usage scenario.

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..
