Yes I’m not asking @Mantafoils for a plotting application, a tool will plot the data provided by the data logger. A spreadsheet could even do that with a csv file containing 10 to 20 coordinates. An Open Office macro can do that.

I don’t, however prop rpm ranging from a to b at determined steps is a working framework easily understandable / reproducible from anywhere in the world to compare N wings/props/motors during the same session preferably on a lake or calm sea without wind or current.

Have you noticed that when it comes to comparison, today there’s no polar/visual tool to say that a given prop is better than another one according to a given criterion (speed range /autonomy, …).

A cruise control via motor RPM triggered from the remote with the ability to go up in, say, 500rpm increments can offer that. This protocol could allow to superpose curves coming from Russia with cuves coming from Tampa 🤙

[Edit] how does a mast thickness influence speed, here Axis 16mm vs Axis 19mm ? A tailored mission for a stepped rpm cruise control remote:

> Foil surfers prefer the 119x19 chord at low speed Kitefoilers and efoilers the 16mm probably because drag is more noticeable at higher speed.
