These pages from vintage modeling magazines like Flying Aces, Air Trails, American Modeler, American Aircraft Modeler, Young Men, Flying Models, Model Airplane News, R/C Modeler, captured the era. All copyrights acknowledged.

Although I have never owned or run one of the vintage ignition type model airplane engines, the articles telling of their operation makes me glad that glow engines were the powerplant du jour by the time I entered the modeling realm in the late 1960s. Just as the smaller A−size and smaller glow fuel engines are generally more finicky to start and adjust to run consistently, so were the similar sized ignition engines - like the Arden .099 probably was. Persistence and anticipation of the joy of hearing a model airplane engine fire up and scream - and of course the smell of the burning glow fuel - as you prepare to launch the craft skyward is what made all the hassle worth it. My friends and I spend untold amounts of time struggling to get our Cox .049s started and running well enough get a few turns around the control line circle before the carefully tweaked needle valve setting no longer caused the engine to run as it did a few short moments ago. Still, we never gave up - and, truthfully, never did much better at getting the danged things to run consistently through  full tank of glow fuel. 

The Inside Story of the Arden .099 Engine

Superior Performance

A steel piston that is centerless lapped to give perfect fit to the cylinder. Serves to reduce frictional loss of power while maintaining perfect compression. The ball and socket joint permits piston to rotate as it reciprocates ... even distribution of wear.

360° exhaust and intake portings. Exhaust gases, expelled radially at bottom of stroke, are replaced by incoming fresh fuel having jet spray feed. Results in perfect operation and starting dependability. A one-piece steel cylinder with 20 cooling fins permits continuous operation at high speeds without overheating.

Radial engine mount that facilitates solid, 360° flush mounting directly to the fire wall. Reduces possibility of excessive vibration.

Timer design features a screw adjustment for fixed timer point ... a friction-free earn roller ... a beryllium copper timer arm, all of which insures efficient timing even at excessive speeds. Note unique housing which serves to protect entire timer assembly against seepage of oil and dust.
