Hi Gang. First post!
I’m writing because I just maiden flew a Seaduck build and had a hard time keeping it under control. It was obviously pulling maybe twice as hard on the port engine. This is my first experience with a twin motors.
-I attempted to try for matching in the mix but it was not consistent.
-yes I calibrated esc’s.
-yes to counter rotation and matched props.
-Also happens with no differential thrust mix, same values to both esc’s.
Should I be trying an FC with oneshot 125 to get a guaranteed match between the two motors?
Do I just have a bad motor? Should all motors passing qc pull exactly the same if wired in parallel and given equal calibrated pwm signal?
I had a lot of fun making the Seaduck. It’s a great project. Luckily it just barely fits in the back seat of my car. If the wings were 1 inch longer, no dice.
Thanks in advance!
