XLPower 550 Nitro
First test flights
XLPower 550 Nitro? Yes, this is reality, although not an official XLPower product. This is a private project popped up on Youtube. This video introduces the heli in detail, how it's built and converted from a standard XLPower 550. The last autorotation landing is not the best, fortunately only servo horns and a landing skid suffer damages.
