You can hoover? Vaccumes can't fly. lol
But no the question pertaining to the quality is nothing like walkera. E-sky and walkera are in completely different catagories when it comes to quality. Every walkera heli i've seen or worked on has had problems or poor quality parts. I have owned 3 esky's with the stock electronics and have yet needed to replace the parts for any of them.
Some people would say you need to upgrade the speed control and gyro, but if you are a newb the stock electronics are more than enough to meet the demands, as you go along and break things here and there.... then I would upgrade instead of buying the same stock parts. The only thing I would upgrade right off the batt is the motor and esc if you are using the non brushless but the benefit of buying the belt cp ready to fly is it "DOES" come with brushless, lipo and BL speed control.
The belt cp is a great way to start out if your fixed for cash and cant buy a dragonus or t-rex.
