Another question; how much torque is needed to turn the rangefinder between the two points? Is the HS-77BB Low Profile servo essential? The reason I ask is I'm not so sure my head will fit in my helmet with the servo, even with the low profile option, so I was considering buying a Hi-tech mini servo instead, the difference being that with the smaller size, the servo has less power.
The recommended Low Profile servo used in this thread has a torque of 76oz/inch (5.5kg/cm), whereas the HS-225BB Mighty Mini has a torque of 67oz/inch (4.8kg/cm). Is there a minimum torque I should be looking out for?
