The ASH-25e indicates a sustainer engine of only 25 hp. Don't think
you want to try using it for takeoff,

lol! Wasn't intending too!

The straight 25
(no engine and 2 pilots) is near equal to the Nimbus 3 with water. Our
25e with engine removed and 2 pilots came in about 1600 lbs.

Both the nimbus 3 and ASH 25's have MAUW's of 750kg. The ASH(e) is
about 40kg heavier empty so in theory we are talking something like
the equivalent of a Nimbus 3 with about 75l of water on board if it
has two 'average' pilots in it
