I will grant you that the application for use of a CAR to save the weight of a servo may not seem worth the effort when you consider the current servo technology. But then again whether you use this or some other method the idea of a CAR [coupled aileron and rudder] does bring flying RC a bit closer to the way the average full scale are flown.

QUIZ OF THE MONTH

Topic - Basic RC Engine Operating Cycle
Below is a list of 18 individual steps in the operating cycle of an RC engine.
Number the individual steps in their correct order.

more up stroke closes by-pass port(number?)
piston forced downwards(number?)
overlap period where both ports are open some mix also goes out(number?)
scavenging-mix coming in helps push out gases(number?)
burn mixture expands(number?)
fuel/air compressed by up stroke and is ignited by glow plug(number?)

QUIZ OF THE MONTH (con’t)

next closes exhaust port(number?)
fuel/air mix in the crankcase is compressed(number?)
more down stroke opens the by-pass port to bring in fuel/air mix(number?)
thus turnining the prop (bolted on)(number?)
this turns the crankshaft(number?)
cycle repeats(number?)
crankshaft intake port opens(number?)
up stroke creates pressure differential (vacuum) drawing fuel/air through carburetor(number?)
fuel is ignited by the glow plug(number?)
down stroke uncovers exhaust port(number?)
gases go out the port(number?)
(BDC) bottom dead center piston then begins up stroke(number?)
Answers at the next meeting...
