C337 Skymaster was tested by real pilots who certified that the flight dynamics are correct.
Many tests have been done in several aspects of flight like takeoff, climb, cruise, glide, descend, stall and overall one engine behavior.
Testimonials:
Julio Arphent
Julio is a retired C337 pilot. He flew the Skymaster more than 2000 hours when we worked in a fishing company. We flew in several conditions an especially at night for detecting fish shoals over the ocean.
“This recreation of the Skymaster remembers my days flying over the ocean. I have been waiting a long time the day when I can get on of a good Skymaster in term of visuals and behavior in FSX and I think that day finally arrived.”
