A quick demo and thoughts on this small cheap transmitter for frsky / futaba from banggood.
It arrived with futaba fw and a futaba reciever which worked but I wanted to use it with frsky so I flashed new f/w as per instructions on banggood sales page.
It all went fine and now I can control frsky quads with this tx, the control was not as good as with my taranis so I only flew once and then bound the Rx back to taranis and will keep this for another time perhaps when my daughter is back to flying with me.
I will upload a flying video soon as I build my next quad and bind this to it.
In short it's good for a small tx to fit in your pocket and better than stock toy txs , ok for flying level mode but acro was difficult indoors due to gimbal quality.

Adding hall sensor gimbals is a nice upgrade but not essential
