This weekend I am going to test these 2 builds.
The difference between them is that one has 7000kv motors and 3 inch biblade props.. And the other has 8000kv on 2.5 inch biblades.
Jhemcu 35a elrs aio
Happymodel 1103 motors.
Walksnail 1s lite with copper heatsink and singularity antenne.
Crux3 frame
550mah hv 2s lipo
My original 2.5 inch version had too much frame flex. So I went for new crux3 frame. Little bigger, but way much stiffer.
I flies now with 3 inch props. But I think I will go back to 65mm biblades. I need to mod the frame for that. It is using the 4x4 bolt pattern. And I need to drill in the 9mm X3 Pattern.
I took off the heatsink of my walksnail kit. But I think the unit was throttling after that. I placed a copper heatsink to avoid the throttling.
