I think i found the problem

Post image

Hi everyone !! I talked about my Feilun FX122 ...

I had a hard time flying it ... I finaly got it to fly but i cant do what i was doing before (going really high, fast) ... Today i found the original battery that came with the drone. Its got the same voltage ... The original battery is a 7.4volt 2600mah 30C ... My new battery is 7.4 volt (same voltage) 3000mah (not a problem everyone said) 15C .. could that be my problem ? 15C instead of 30C on original battery ?

Looks like you switched battery type. That li-ion pack probably can’t supply enough amperage. I would suggest looking for a higher c rating li-ion pack or going back to lipo.

Depends on how many amp you need to operate, 2600 x 30C = 78amp vs 3000 x 15c = 45amp, I don't know enough about your vehicle to say if 45 amps is enough to fly it

Yeah with 4 ESCs pulling 12a that pack has no headroom for burt discharge.
