Hello,
I fly in Mexico City at an altitude of 8000 feet above sea level so we lose about 25% of power compared with sea level fliers. I´ve just bought a U Can Do .46 and I am not sure which engine to install. I have a Supertigre .75 2 stroke a .82 Saito 4 stroke and a OS .91 2 stroke. I´m not sure I want to install the 2 strokes due the inverted position of the engine. Since all of you have flied this plane and many people overpower it, any suggestions?

Thanks
Eugenio
