It's a 350 qx blade. I'll double check these blades, thanks for the suggestion. I'll add throttle, but when it should be taking off, it starts flipping over one way really fast, multiple times instead.
I defiantly sounds like you have the props swapped.
another way is to have a mate hold down the craft while you throttled up and if you feel any air flow upwards above the props
that is a dead giveaway.
Just be careful that you don't loose a finger.
And you trust your mate to hold it properly.
Hi +1 to what Charles said props on wrong , most quad set up are 2 front props turn towards each other the 2 back away from each other ( looking on top with back arms towards you) when plug the quad in dont move it or touch it or the transmitter for 3/5 seconds to allow gyros to set up if it has GPS it may take a little longer watch the signal light on the quad so you know when its ready to fly
