Hi all!
I'm playing around with different rpm sensors. I like the optical sensor, pretty good results. Than I tested the brushless sensor. Results are a "little" bit different... is this something common? Conditions were pretty much the same. No chance of using both together? I used only one connection for the brushless sensor... perhaps a second one helps?

Looks to me like the brushless sensor responds to changes faster - since that trace looks more like your current and power traces....while the optical sort of averages out the variations that are showing up.

Why are the power and current traces so choppy? - seems odd to me...

Hi!
These graphs where taken with heli standing on the floor... no hovering or something else. Just 0 degree pitch...
Based on the feeling when flying the Governor holds head speed really well. The brushless curve looks wired to me.
About power&current... looks different when taking a graph with flying. I'll test with a second brushless connection tomorrow. Perhaps that helps.
