of course, I didn't know much about rc helicopter at the moment I bought this one.. I see now that the quality is not quite exceptional... but it is pretty frustrating to see my friend's helicopter which is the exact same model flying really well while mine is not stable at all... I'm not sure if I'm wiling to invest any more money in rc helicopter, eventho 20$ for the model you suggested is very abordable...

I would like to see first if I can receive answer for my question here before making any further purchase
