Hi All,

I plan to buy flight controller.
1st is Qq Super Flight Control Board.
2nd is KK 2.1.5 Multicopter Board.

Can you guys suggest me which one is best for quardcopter for stable flight & also tell me what is self level in KK 2.1.5?

Go for kk 2.1.5 board. It's much better for self stabilisation
Self level means that the multirotor is able to stabilise it altitude without going up and down instantaneously.. The qq lacks this ability and so if you buy this then your quad might not stay at a specific altitude and you will have to change the throttle  stick continuously.

go for kk2 or kk2.1 5 , self level is when the quad returns to level after u give a stick input. in normal mode once u give stick input, quad continues with the last input, u have to correct ur self.

@darshan, kk2etc dont have barometer, ure describing altitude hold, self level just levels the quad(u control throttle), doesnt hold alt.

Thanks All
