WHOW this was a mis-buy. For me,
comming from a year crashless fixed pitch big heli flying.After reading a lot, the common findings on fora are that the kds is not set up proparly by the manufacturer workers !! So it is anti – RTF
Even beginner instructions, like how to set up the transmitter… do not exist. Then i found someone with the ‘same set’ but in real life his transmitter and/or servos where different.
After that i almost got chopped by the spinng blades, even with idle/0 throttle set… SCARY ! Because lets face it, it is a powerfull flying meat grinder.
One has to be an experienced 3D flyer to even set this thing up, check the helicopter from head to toe, And has to be a mechanic aswell a pilot.
And even if you find, like i did, someone with i.e. a year older model, ‘same’ set (heli C and transmitter) the settings are allready different due to different menu entry’s and/or servo attachment.
KDS should make a beginners setting pdf / A4 paper !
