Dear chitolin and Panama Jack,
Thanks to your information, I could have a good flight at Golden Wings to Masaya, Granada and the Pacific Coast in C-172.
Though it was windy and bumpy, the view of volcanos, the Lago Nicaragua and the coasts were beautiful.
Next time I will be back in October with longer schedule. I will apply for the conversion next time.
The club has C-152, C-172, Piper Seneca and some other aircrafts. They are quite freindly and welcome every visitor.
Gracias Nicaragua!
