I'm cautiously optimistic. Been waiting for this Catto to come out for a while. Not sure when the Rotax setup will be publicly available, they only just started making the rotax hub a couple weeks ago I think.
The E-prop IFA looks great too, but it has an IFA price tag. The Catto is typically on the high end of fixed props ($ and quality).
Curious to see how this shakes out. I hope they don't want IFA money for a ground adjustable.
