I have ordered a FrSky transmitter for 200$ on the 9th of November. After twenty days I got the message that they had a delay in the shipment. Well till now the transmitter has not arrived and Banggood does not answer to my requests. Actually I just received a cheap battery that I did not order and do not need. Now it is the beginning of February. Unfortunately all my hope to get the transmitter is gone. NEVER AGAIN! DO NOT BUY ANY STUFF THERE!
