Ok, 1st - Brushed motors suck. They always have, and always will. I go out and buy a dremel tool, within a year, I have to replace the brushes. Brushed motors SUCK. Anytime you have a mechanical device that uses friction, parts are going to wear out. Lifespan is determined by, how hard you run it, and how often, and how long. In most RC applications, the brushed motor is OVER voltaged, OVER heated, and generally run like a ragged dog. So its no surprise that they fail...and rapidly. Instead of B***chin about the "longevity" of brushed motors, learn how they work. Ive seen tons of people come onto these boards. They want to fly, but dont want to put the effort into understanding how or why they fly. Nothing works all the time. Even your car requires maintenance. If you bought one of those POS Fords, and the alternator goes out 2 days after you get it, do you think Ford is going to take back the whole car and give you another one....HELL NO. They will probably do exactly what century is doing and give you a new "motor(alternator)". 2nd - Everybody wants a quality machine, but they arent willing to pay for it. How many times do we see threads on here entitled "Looking for cheap beginner heli" or "Need cheap good heli". Its an oxymoron. You cant get a good cheap heli. Either its cheap because its built with less quality, uncompleted, stock, or garbage. Or its good and expensive. You pay for what you get. 3rd - Stock motors are exactly that ...."STOCK" They are just some random motor the factory had in "stock" and threw in for free so that at the very least you could get it up and flying. I once called a factory and asked them why they didnt make a package deal with brushless motors. They told me "So many people like different brands of brushless motors, that its just not economically feasible to stock and supply that many different brands." I can understand that. For one helicopter, there is probably 15 different possible motor combinations. Not to mention the different ESC combinations needed to run them. NO company in the world could afford to do that.......SO......they leave it up to you to choose what you want. 4th - Everyone gripes because they bought a heli with a plastic head, and it should be made of aluminum. Ok. You payed $79 bucks for a barebones heli. Its got a plastic head. The factory that made the heli has a big $40,000 plastic injection molding machine, and they can pump out thousands of the parts everyday. This mass manufacturing is why your heli only costs $79 bucks. Now you have another factory that is cranking out aluminum head helis. They cant mold aluminum head parts, they have to mill them. So they have (20) $20,000 a piece CNC milling machines running 24 hours a day with Mini-Mite tables cutting head parts. Your heli now costs $300 bucks for barebones.... WELL duh. Final comments. You get what you pay for, and you cant get high performance from stock. This doesnt just apply to RC.
