New Foil Assist: here is the "TakeOff" from Manta Foils

This is all we have from Manta Foils

Did they show a TakeOff prototype ?

As we were there on day one, we did not see it, however they might have done so later in the week.

The takeoff prototype was there all the time. You can see it on the picture on the axis mast.

Having said that the video renders of the crowd funding campaign have more recent design.
