If anyone is looking for a suitable mount for up to 10" tablets which fits the existing 3/4" ball mount of your transmitter, I can thoroughly recommend the SATECHI ST-TP01 If fits superbly, has fully adjustable arms, and an incredible suction device which holds onto the back of the tablet, which locks down. The whole thing then just tightens onto the ball joint and you have a rock steady tablet to enjoy your FPV without any modifications to your existing setup, so if you are like me (I have a Samsung Tab3 8.0" Tablet for flying) and you dont want to mess around modding, then I dont think you can do better than this item. A great buy and can recommend it. I got mine from Ebay US as could not find one in the UK. Enjoy !
