| With regards to my crank sensor problem, it is clearly a vibration problem, one that should have been addressed by the design engineers, not by me, the end user. (The new sensor will addressed by me once I get it and encase the thing in epoxy)
The problem as I see it is the green circuit board is not constrained to the plastic case by any method. The circuit board is held in position by the 4 solid pins from the hall sensor and what ever support is offered by the 3 wire connection to the receiver. Now that the pins to the hall sensor have all sheared off, I can wiggle the green circuit board with my thumb nail. I would think an unconstrained mass attached to solid conductors, bolted to the prime source of high frequency vibration to be considered a bad engineering idea.
From my point of view this is clearly a design problem. Perhaps it was exasperated by my setup, or perhaps the YS-80 motor shares some resonance with the circuit board. I don't, I'm not smart enough to answer the question.
Installing the sensor isn't rocket science, and I don't really see how it could be done improperly. I mean it's hard mounted to the motor, how exactly would I shield it from vibrations? I've got 0.003inch of run out on the clutch / fan hub, I also balanced the clutch / fan hub assembly.
Also, I gotta admit, it seems freaking silly that the first thing I have to do to my new receiver is take it apart and address a manufacturing flaw on the antenna mount, perhaps I am just not a hard core modeler..

Now that I've re-read his post I think he was offering condolences, not scorn..
