I guess a Moderator can boot me off.
I have no problem in posting repairs I have made. I would think that if someone were interested in buying a new TC, they would want to know where the weak spots were. What a better way to tell than look at an older one.
I have owned several TCs through the years, all previously owned. I think I have made just about every repair you could encounter on a TC.
The following is a link to my Bigfoot TC and related toys:

I am continuously upgrading my TC, and have done several repairs, so far, none really serious. I am the second owner, and the previous owner made no repairs.
My experience is that there is no TC design that is better than the Bigfoot when it comes to maintenance and longevity. I can see some areas of poor design, but they are not serious.
