I would agree that Hobby Lobby does recommend a decent power system. They do like to push AXI and Jeti. While these systems work fine, there are other possibilities. You could use a Hacker A20-20L (my personal favorite) or a Hacker A20-22L, a Himaxx HC2212-0890 or HC 2216-0990. You could use one of the E-flite motors such as the 350 outrunner. You would be looking for a motor of the same size as the AXI with a Kv of 925-1050 or so.

Any good speed control in the 18-25 amps range will work well. Besides the Jeti you could use the Castle Creations Phoenix 25 or the ThunderBird 18. You could also use the e-flite 20. These are the ESC's I am familiar with, there are others.
