I use a Cessna 172S for pleasure and some business travel. We have 398 kg useful load, a fuel burn of 32-36 liters/h, and app 115 kt trothled back.
We are operating on a 500 mtr grass strip. I don't fly with more than 3 persons and don't need to.
I have been looking at the Tecnam as a possible future replacement. Mainly because of the mogas capability and the twin reliability.
As I understand the G-ZOOG is without autopilot but I don't think that will add alot to the empty weight. Besides that the two aircrafts are quite similar in useful load. The Tecnam is 20kts faster using 5-6 liters more per hour.
I think the Tecnam has better takeoff performance but I'm not sure about that.
I still consider the Tecnam as a future upgrade candidate because of lower mogas fuel costs and I'm doing a lot of sea crossings where the twin could be nice.
For now I'm saving or hopping to win the lottery. Could be nice with a Rotax Factory Injected 912 with 10-15 more hp
