Hello Wayne,
the 582 was already installed as I bought the aircraft. It is a light-weight engine, just 65 HP, and drinks a lot for the performance. The 582 is OK but a little too weak for 2 persons and hot weather like now (Brazilian summer with temp. about 32 °C). The real advantage is the weight, but I also considered a Hirth with electronic injection. The problem is that Hirth has no representative in Brazil and I heard that some new regulation to come will afford 4 stroke power plants... But back to you, is the 3701 84 or 100 HP ? I think either one would be a very good choice! If you decide to install one of them, I would be very interested to learn your experiences from you. Maybe that new regulation I mentioned would accept "clean" 2 stroke engines like the new generation Hirths.

Hello Sergio,
Let me know how this setup performs, I'm looking at putting a 3701 Hirth on mine.

Pedro,
thank you for the 5 stars! The temperature range here varies quite strongly between summer and winter. During summer (now), it reaches about 32 °C (this year) and during winter it can fall down to some 10 °C. During the summer, one has to pay attention not to allow temp. to rise above 90-95 °C, best being 80 °C.
Saludos
Sergio

I give you 5 stars for the two stroke engine!, what's the temperature range where you fly ?, I ask because of the radiator install inside the cowling.

Saludos
Pedro
