I would purchase a good used sc10 FT from a reputable seller, or new if you have the $$. Then add your new electronics to get it going. I prefer new electronics as you start with a fresh warranty etc. You will get much more bang for your buck going this way than the rtr IMO. Everyone seems to be running Tekin nowadays, kinda pricey but everyone seems to like them as they sell like hotcakes when they come up in the used for sale section on here or anywhere else.
