The testing customers were positively thrilled about the way Diana 2 is
flying. Some feedback: the glider is easy to fly and also safe. None of

make the glider spin or stall completely.

Mr Sharma said to me personally that he had only 200 hours and
no experience on racing class gliders.

Hmmm... Now, you must decide: Is that glider (15m!) "easy and safe to
fly" or do you need more than 200 hours to be able to handle it?
