Welcome to RCTALK.COM!!!
I am curious... what brand of rc's are these?
Is parts availibility the only reason you want to sent out for repairs rather than repairing them yourself?
I work on my RCs more than I drive them I think. I enjoy working on them.
There is nothing on my RCs that I can't fix. That comes in handy EVERY TIME I break a part, hear a funny noise...
If you send your RCs out, you won't learn how to repair them. If you have tools and time, we are pretty good at helping ppl thru the tough spots.
I think you should break out the tools and start making a parts list.
Jennysrc.com is a great source for new take-off parts at great savings.
I source a lot of hard to find parts from ebay too.
I hope you'll reconsider making the repairs yourself.
