It's the engine with a Brain. A built-in
computer sets this engine apart from the competition.
It's the absolute
ultimate in sophistication for an R/C airplane engine
shattering all pre-conceived notions about just
how high-tech an engine can get! The 1.40 RX-FI from O.S.®
utilizes advanced electronics to constantly monitor
engine rpm, calculate the fuel required at any given
moment for maximum performance, and then deliver that
exact amount of fuel to the engine. The result? The
smoothest-running, most consistently powerful 2-stroke
engine imaginable, and a natural choice for FAI F3A
competitors, or any modeler who wants to equip their
plane with state-of-the-art engine technology.
Here's how the 1.40 RX-FI
Two sensors constantly
supply vital information about the engine's changing
conditions to the EC-1 Electronic Control Unit. Based on
this data, the EC-1 commands the injector to supply the
optimum quantity of fuel to the engine at all times.
The 1.40 RX-FI
rates extremely high in all of these areas:
The Electronic Fuel Injection system constantly
supplies the correct fuel/air mix to the engine,
regardless of speed, altitude or attitude.
RESPONSE: Very little trim is needed to
set up the engine perfectly; even at low speeds,
the idle is reliable, so you can concentrate on
Once adjustments are made, the 1.40 RX-FI engine
holds them very well.
The 1.40 RX-FI creates the kind of pulling
power that pattern fliers need for
maneuvers that demand steep climbs, and it works
with 15% nitro fuel.
With fewer moving parts (no valves, camshaft, etc.),
the 1.40 RX-FI is easier and cheaper to set up
and maintain than a 4-stroke.
FEATURES: The 1.40 RX-FI also boasts the
advantages of lower noise output than a 4-stroke,
excellent fuel consumption and minimal vibration
||The display panel normally
shows engine rpm, but it also has a
memory function for recording the highest
rpm and engine temperature during each
rotational speed of the crankpin, and feeds this
information back to the control unit.

through a solenoid-operated valve controlled by
the EC-1 unit. Fuel pressure is generated within
the crankcase and is automatically regulated.
