RC Engines & Fuel
Everything that burns fuel lives here. The engines come first, shelved by brand because that is how most people shop for them — O.S. for two-stroke and four-stroke glow and the GT/GGT/GF petrols, Saito for four-stroke glow and FG petrol singles, twins and radials, DLE for 20cc to 222cc petrol — with two browse-by-fuel shelves on top: Petrol Engines for every petrol unit in one place, and Glow/Nitro Engines split Aircraft and Surface so the Traxxas, Force, Argus and Alpha car engines sit apart from the aeros.
Then the keep-it-running shelves. Engine Parts is organised brand by brand and engine by engine, so an O.S. MAX-46AX or a Saito FA-82B has its own page of gaskets, bearings, carburettor parts and screws. Glow plugs and spark plugs, mufflers and tuned pipes, mounts and standoffs, electric starters, glow igniters and power panels each have a shelf, and the fuel section carries Redback glow and nitro fuel, Klotz oils, Dubro tanks, fuel line, filters, fuelling valves and pumps.
