simoman You've got an 12A ESC only in the Skip, so You should be careful a bit. There is a note in Your description that 3 blade Props are not recomended at 3s or even 4s. I fly these on my Eachine Twig: Very nice and smooth props and low noise also. But I fly them mostly at 2s, for 3s I use the 2,5" 3-blade-props.

simoman You have to decide which voltage You're gona need and choose this specific one!

simoman Seemslike the antennas are not available as spare-parts. You might use a similar antenna with u.fl-connector. Worth a try?!

simoman Yesthere is one battery in the camera, might be wise to order another for extended usage outside...
