MOSFET driven quad question.

Post by arolds »

Hello. Firstly, i hope this is the right section of the forum for this.

I have build a arduino based quad, have multiwii 2.4 uploaded to it.
It is a very small build, and i used brushed motors in conjunction with MOSFETs (no esc). Also, i don't have a transmitter, instead i use the Ez-GUI app.
So, if i have the dynbalance option on, when i test the motors on ez-gui, the motor run all the way to full power. When i get the dynbalance off and proceed to control the quad, it arms, but the thrust output is not even close to max with the thrust slider all the way up.

Is there some sort of special code for MOSFET driven motors? The only option i found was the EXT_MOTOR_xKHZ, which i have the 4hz option uncommented.
BTW, I am using hubsan x4 motors and battery, so I would think the battery is NOT the limiting factor.

Just for clarification, I am using an arduino NANO with a gy-85. I am getting the gyro data pretty accurately.
Also, my maxthrottle is set to 2000.
