I don't fly this any more,but it had an honorable demise.
i used my own receiver, they operate on the foxtec frequency's, there not fatshark compatible. i took it out 800m with good video. i now use 1.3 ghz, my next micro fpv will have a foxtec 1.3 ghx 200mw vtx
the last setup i had was 2*500 mah 3s battery mounted in the wing (trappy zephyr style),
one of those 10$ osd's,
a security camera 2000 600 tv line camera with a servo pan,
36 mhz corona receiver,
24 gram motor 6" prop (i think)
and a heap of hotglue
im not sure what the all up weight of that was, but it handled it fine! still flew slow and easy to launch, as long as the c/g is corect, c/g on theese small wings is crucial, within millimeters.
hope that helps! let us know how you go,
