Which should be the one that came with your RTR DEX210. A 10.5t motor or even pushing it with a 9.5t motor on that ESC would give you plenty of speed if all you wanted to do was bash and have fun jumping. If you put too much power in it and try to bash, I am sure you will be breaking stuff and without a local hobby shop, that leads to down time.

If I were in your shoes, I would either get another 13.5t speed passion motor or go for a bit more punch and grab a 10.5t since they are the same price.
