I don't use my Fatsharks much because I can't read the OSD without glasses. I bought two FX797T camera / vtx's in part to get more practice with the Fatshark's. It's harder than I thought. And "MicroFPVmod G" is right, she crashes on the antenna every time. I've set the timer in my Devo-10 transmitter to three minutes, by then the battery is getting warm. And now I let the motors cool off between runs. Tina's page is here: http://mavn.us/quads/Tina/tina.htm .
