As a recent convert from GA flying, I did a lot of research before eventually deciding to purchase a Tecnam P92 Echo Super with a rotax 912ULS (100hp). One peculiarity of the Tecnam is that it has a tank in each wing, with surplus fuel returned to the left tank, and during my familiarisation training I had been warned that it was possible when flying with full tanks that fuel could be pumped overboard via the left tank overflow.

This could be devastating to your fuel calculations on a long trip. The Tecnam is fitted with a valve for each tank on the relevant door frame, so it is a simple matter to turn off the right tank during post takeoff checks, so that all fuel is drawn from the left until the level is reduced enough to prevent losing fuel overboard.
