Yep, thats the draw back. It can fly in 10mph winds, IF you're experienced. Students are just not steady enough for that, and mine were grounded too. But my glow students flew in winds up to 15mph. My favorite trainer is the Hobbistar 60 with the Alpha 40 next. I point everybody away from the Nexstar. They're just not durable enough to take the punishment a student is gonna give it. The main problem is the landing gear. It usually rips out the under carrige when it hits something. The trainers with wire gear just bend. Bend it back to shape and you're good to go. So far, every student that changed from Nexstar to something else notices the difference right away. If they insist, I'll train them on the Nexstar, it doesnt matter to me.
