It looks like maybe I should get a glow plane next. However, I'm completely unfamiliar with nitro engines, so was thinking about going ahead and get that r/c truck I've wanted with a nitro engine -- that way I can learn how to run and tune them on something that won't die a gruesome death when the engine stops running

So, I'll fly the Slow Stick a while longer and look into getting a glow trainer type plane after that.. thanks for everyone's input!
