I'll tell you another good place to get things that are helpful is estate sales. I go to estates all the time. About 3 weeks ago I went to one and they had model airplane stuff. I bought a good OS 52 four stroke, 3 feet of fuel line, exacto knife, heat gun, 3 foot metal ruler, 1 foot ruler, electric motor, esc and servo, ALL for $7.00.
Other sales I have bought sand paper, drills, band saw, dremel tools, soldering irons, etc.
You guys should try them too.
