Cox .049 Surestart Glow Engine

Description

For those of you who have been in the hobby for a while the name "Cox" will be no stranger. Many of us started into the hobby with a Cox plastic control line model and many RCers have used the venerable Cox .049 in various forms to power small aircraft, gliders and even helicopters.

Cox engines use a hardened, formed-steel piston which runs in a softer steel cylinder, this does mean however that they require a reasonable break-in time before they get really consistent but this does pay of in the long run with a engine that will go on for years and years. These engines have the typical Cox extruded crankcase, rear mylar reed valve, counter weighted crankshaft with pressed on aluminum drive washer. The backplate is a moulded plastic and incorporates the needle valve assembly and air intake, it also acts as the radial mount for mounting the engine. The conrod is Cox's traditional captured ball and socket link to the steel piston and the one piece machined steel cylinder has bypass ports and slots for the exhaust. Due to this engine having a reed valve fitted between the backplate and the crankcase this will allow the engine to run either clockwise or counter-clockwise, this is determined in which direction you flick it to start, so its great for normal tractor and pusher designed models. The Cox .049 Surestart engine has been developed by Cox to be really easy to start and comes complete with a longer lasting brass drive -plate.

Enjoy the fun and excitement of running a small glow engine for a relatively low price and for those of us who remember them from years ago, re-live a little bit of your childhood.

NB: Cox glow engines have a glowhead that requires a 1.2-1.5v power source, do not use anything with a higher voltage or it will blow the element, also best to use fuel with a nitro content of 20% or more.
