Hi.
I would like to upgrade my ATLAS antennas with this mod. So, is it really better with this 2in1 antenna? Have you performed a comparison test? Thank you
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.
Seb
Sorry for the late reply, I already uploaded the two print files(Antenna Mount and and TBS RX Mount ).

In addition, in order to space for the power cable, the O3 unit requires additional nylon spacers.

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 !

I uploaded the foloding antenna mount,can use it as a design reference.
Thanks for the link ! I have already made on for my LR5

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.
What's the flight time with the 850
