Just purchased (all from FT Store online ) a Tiny Trainer, Power Pack A, a Tattu 850mAh 11.1V 45C 3S1P Lipo Battery Pack With XT-30 Plug, Spektrum DSX transmitter, Spektrum AR620 receiver, and I have battery question: The plugs on the Tattu battery won't fit on the AR620 receiver. The receiver has 3 prongs; the battery has 4 prongs. I also have an eflight 30C 2S 7.4V 800MAh; that doesn't fit either.
The servos & ESC do fit the receiver.
Do I have the wrong battery, the wrong receiver, or both? I am hoping to build this starting next week when I am watching grandkids for a few days.
Thanks in advance
