RJL is the worlds largest producer of old time vintage model engines.

Please be sure you know these are antique type engines and
are not suitable for modern modeling. If you don't know what you're buying,
DON'T BUY IT. These engines has very specialized applications.


All castings are made from original molds and all machined parts are held
to exacting standards so you won’t be able to tell ours from one produced 50 years ago.

Cunningham Blue Streak .647 Spark Ignition Version engine

Part No. 99-1501

Cunningham Blue Streak .647 Glow Version engine

Part No. 99-1502

Ball bearing crankshaft • Lapped iron piston • Loop scavenged
Bore: .937 • Stroke: .937 • Displacement: .647
Weight: 12.1 oz (glow version) • 12.6 oz (ignition version)

The Cunningham Blue Streak .647 is basically a Orwick with
a ball bearing crankshaft and cast on mounting lugs and venturi.
Produced in the forties, it is a very rare engine as very few were made.
It's actually better than the Orwick because it has
a more conventional design and a ball bearing crank.

Like the originals, these current production models feature a
lapped iron piston, bar stock connecting rod, and
ball bearing crankshaft. The originals came with a "make" timer
which the cam actually closes the contact point. Our current production
comes standard with a "break" type (same as Orwick) timer
where the cam opens the contact.

Differences from the original
Knurled prop drive  •  Orwick style timer on ignition version standard
Original style timer optional extra  •  Slightly larger crank diameter & rear bearing
Better looking blue finish.

EDCO .19 Sky Devil Engine
A 2/3 scale version of the famous Sky Devil spark ignition racing engine.

Probably one of the rarest engines,
it was the largest diesel produced
in the U.S. and was to be
marketed after the war.

 EDCO .65 Sky Devil Engine

All castings and machined parts are held to exacting standards,
actually better then the ones produced 50 years ago.

Forster 99 with 2 speed ignition timer

No other current production vintage engine offers the unique design and
quality construction of the Forster 99.
RJL had used the original casting dies and the latest
computer controlled machinery to bring you this piece of modeling history.

The Forster 99 ignition engine first appeared on the market in 1936
and was sold thru the 1950's. Many features of the day included two speed timer
to allow a low/high speed by retarding the spark timing, ball bearing crankshaft,
and bronze bushed connecting rod. This well known favorite of many modelers
produces .68 horsepower and swings a 14 to 16 inch propeller with ease.

Please Note: All our vintage engines are made on the same machinery as our production R/C engines, however, the quantities are far smaller. For this reason we usually produce the vintage engine parts when time is available during our normal production runs of similar parts. This results in some of the vintage engines not being available for some period of time. Check stock status on this website.

Rest assured it is being worked on, but we do have to finish all the parts before we can sell it.
Thanks for your patience.
