Hello,
I see reference to using the Eagle Tree phase sensor with a Skookum FBL unit in this post: https://rc.runryder.com/p5374408/. What other FBL units have folks tried the ET sensor with?

Thanks,
John

ET sensor does not give a very clean output, lot's of spikes and interference, that's why I went and recommended Hyperion instead which produce a much more clean signal.

MrMel,
Agreed, looking at the ET sensor output on a scope was a bit disappointing as to its consistency and signal shape. Despite that, I was just curious if anyone has successfully used them with any of the FBL units.

Swap red/black and it 'works' with vbar but with some hickups (kicks on tail etc)

So, pretty much not worth even considering it sounds. The output just isn't clean enough for the units to make good use of.

I suppose ET must be handling output cleanup within their own units because it does work.

Thanks,
John

VBar also clean the input, but for sample, a pulse from the sensor that is "Valid" but far off causing a jump in throttle is bad.

For a logger, it's easier, just average the peaks away.
