I look at these cheap planes as some raw material, not a finished product that is ready to assemble. Those who blindly use all of the pieces provided and expect no problems could be in for a suprise. Many tend to put on more power than what is recommended which can amplify the problems. I never intended to use the cheap plastic spinner from the start. I still have it sitting in my shop. As they say, you get what you pay for. As some of you have stated, it would be better if they left the cheap junk out of the box and reduced the price by a couple of bucks.
