one thing in this hobby is you get what you pay for.nothing wrong in trying to save money but save it on other things.buying a cheap inexpensive motor may save you money now but if it fails is there a warranty for replacement.most of the brand names will stand behind their products,chinese imports you are on your own.I still remember about thirty years ago some guys in the club were buying cheaper kwik links than dubro ,I think there was a fifty cent difference.they lost a few planes because the links failed.you will save money in the long run by buying the best you can afford .
