Yes, the video is older than this forum… April 2017 and I didn’t really notice the prop at the time. Since LIFT have published pictures of their drive train (late 2017), we are all obsessed by the 140-160mm with large blade props in the @Flying_Rodeo style. That’s why I am all the more impressed by Don Montague efoil reaching such a high speed with such a not so short but elongated air propeller in water.
So I was wondering if we had missed something or if members of this forum had investigated the trail and gave up for good reasons.
How many Kv’s for this 240mm (?) prop x 3 inch pitch (guess) ? Geared or direct drive ?
@pacificmeister, you have observed this efoil closely but have you ever thought about investigating such high AR propellers rotating at probably high rpm (200-300kv ?) possibly not geared ?
