Integrate flight control, ESC and VTX together to reduce assembly time, better layout and less interference.
SPAN Tower is developed based on this idea. It includes FC(F405),ESC40A, VTX 5.8g 25/200/600mw. It’s really exciting and it reduces the time it takes to install it.
The heat problem is that this design is the most difficult. Our engineers have been tested in nearly 10 versions and have done a very good thermal isolation, and now we basically don’t have to worry about it.
Please refer to the instruction manual for details.
