NO!

Hi OG! 

Any particular reason to this? sorry i am new to this hobby!

Please do some research on how motors work and different types of motors !

If you use an ESC for brushed motors, why not.

Hi Armin! 
  Am currently using an ECS(MC230CR-Futaba) right now, but the current issue right now is when i pluck it in it just spins away!

I guess you need to adjust the PWM values. Also consider that those ESCs usually also have reverse. I would expect at a 1.5ms PWM pulse with the motor stops. Since multirotor ESCs are usually stop at a 1ms pulse with your flight controller is sending a 1ms pulse with on the beginning, so your motor probably turns in reverse now.
