QX3 throttle problems?

[Rotors]

I recently purchased the Blade QX3. First of all i have the new DX6 radio.
I set it up per instructions and everything seemed OK. Then i took off and the throttle had a mind of its own. first of all it took off on its own after about 20 seconds then stopped and then i slowly increased the throttle and nothing happened and then after a good minute it shot off and bringing it down on the trottle was impossible and only the return home function got me out of trouble.
Then i tried again and the same thing but this time it really shot off and the engine cut so much it came down like a stone cracked of the GP and busted a skid.
Is this faulty or do i need to settle the throttle control as it does not say in the set up.

Hi Rotors try a re bind make sure throttle is zero and it has no sub trim and trim tabs are in the centre (This is important when binding it sets the failsafe )also the left cyclic needs to be left and centre to bind with GPS on,page 8 of the manual

Hi. Yes did all that, i have found out that in 'Smart' mode it tends to be in a slow wind up but much better in agility mode
