I had an Isobar Rudder servo start to fail on me, where
it would worked fine but it only had ~30 oz of torque...

I changed the servo to a brand new one with over 100 oz
and still very week.. say ~30 oz of torque..

I traced the problem back to the Y harness used for the
steering servo and rudder..

You would never know it because everything worked fine
on the ground just no power...

My point is, my Y harness acted like it had a resistor in
it, limiting the current and the output torque.

Any wiring / battery problem will not show up until
its too late..

I think bob cat owners should just measure there elev
torque by hanging weights on the end of them and
compare theirs to all the other bob cat at the field that day...
This could tell a lot and save a plane... !!!

I can bring my scale to Miss Afterburner... and set it up..
Won't take but a sec... If any one will use it...
