I have 2 of them in a Tamiya F-350. They are fine for it. I think because the stress is far less than in racing. They are used for steering (MG-630) which isn't constant as in racing and for shifting (MG-620) gears which is seldom. I've heard bad things about them. I have also never checked to see if they get hot or not during use. I wouldn't try them in my race cars though solely because of the rumours. Remember you get what you pay for.
