dear 老師,
i have try the best way to think about the arrangement .
and i have think about 2 types
1. the original one
Higher motor but more balance for the left and right.
2. the new one
the motor is lower but i do think that the left and right is +/- 20g.
The c.g. for this 2 types of arrangement is almost the same.
i will do both classic to test which is better or not.
