RE: ESKY King 3
if you have the extra cash get the dx6i radio and the 6100 reciever
i dont have this heli but with all 6 channel heli`s you need to do some preflight setup`s
go through the head make sure the swashplate is level
make sure you have full movement in the servo`s
do a tail preflight setup
just everything that makes the heli fly you will need to go over do proper adjustments
yiu can go to helifreak.com theres a guy i think they call him fineless or something like that, that has some youtube video`s on setup and preflight adjustments
did you buy plenty of parts if not you`ll want too
get atleast 2 of everything that deals with the servo`s and the head
