Just got the Eachine Diatone E349SX. It has the Diatone e369 stretched frame and TBS Nano VTX. I swapped the dipole with an AXii 2 antenna with a 3D printed mount from Thingiverse. I added a buzzer with a back-up battery. Not much space under the canopy so I mounted the FRSKY r-xsr on the back of the antenna mount.

All in weight 259.1grams. Gonna need to get some 650 4S packs to bring it under 250 grams.
