Vanquish DIG with MIP driveshafts
 

It seems that if you're running a full sized servo (that's all I had on hand), the bell of the driveshaft slightly rubs against the side of the servo. Additionally, it also keeps the driveshaft from cycling up and down.

The only thing I can think of is to get A: get a micro servo or B: make a lift bracket for the servo mount so that it will clear.

Let me know if anyone else has had this problem and what they did to fix it. Thank you! "thumbsup"
