Brodak Manufacturing’s three new engines provide a new boost for smaller-sized CLmodel
flying. They feature AAC construction and run on 10%-nitro fuel.
ALTHOUGH MOST of today’s piston-powered-model pilots
are RC sport fliers, there are plenty of enthusiasts of CL flying
too. And their numbers are growing!
Much of this enthusiasm has been generated by John Brodak.
From his headquarters in Carmichaels, Pennsylvania, John
operates the world’s largest CL-model-supply business. He has
been continually expanding its scope through the years.
Because few designed-for-CL model engines are being
manufactured anymore, John decided to get into that product line
too. To join his earlier-issued Brodak .40, he recently introduced
three new smaller engines specifically intended for CL flying: an
.049, an .061, and a .25. (A .15 is on the way.)
All three of those new power plants feature aluminum pistons
running in chrome-plated aluminum sleeves. They’re ruggedly
built, good-looking, and come with the most complete yet easyto-
read instruction sheets I’ve ever seen.
None of the new Brodak engines need high-nitromethane fuel
to perform. They start easily and run well on 10%-nitro fuel, at
12,000-17,000 rpm for the 1/2As and roughly 11,000 for the .25—
all depending on the propeller.
The two smaller Brodaks have color-anodized cylinder fins,
hardened-steel propeller retaining screws, well-rounded airintake
openings (to minimize power loss from “inlet stall”), and
high-precision needle valves. They’re lightweight too; with
muffler and propeller the .061 weighs exactly 2 ounces.
Brodak’s .25 looks much like the earlier .40, which greatly
impressed me when it first came out more than three years ago.
The new .25 has essentially the same features: AAC (aluminumaluminum
chrome) piston and cylinder, sleeve-type main
bearing, and closely fitted crankcase to maximize fuel suction.
(CL engines don’t usually use, or need, muffler-pressurized fuel
tanks.)
You can get full details about all the
Brodak engines—and much more—at
www.brodak.com.
Decades ago the Russians and Chinese
began using model-airplane engines as
“teaching tools” in their public schools.
Literally millions of small model diesels
were manufactured for that purpose, such
as the Chinese Silver Swallow .15 and the
Russian MK-17 .09.
I’ve owned both of those for several
years. They’re well made, rugged, start
readily, and run well—not to mention
being remarkably low-priced.
I obtained those power plants from
Carlson Engine Imports, 814 E. Marconi
Bill Jensen restored this used Enya .09 to much-better-than-new
performance. He provides a worksheet detailing everything he does.

Ave., Phoenix AZ 85022. This supplier had been dormant for a
while, but owner Ed Carlson recently reactivated the business. His
Web site—www.carlsonengineimports.net—is still in progress as
I write this, but by the time you read it I’m sure that the various
engine pictures will be in place.
Carlson carries many sizes and types of model engines,
including RC, from Great Britain, Russia, China, India, Italy, and
more. He sells diesel fuel too!
Parts and service are still available for venerable Ohlssons, such as
this 1949 .23 (The final version of the once world-famous “23.”)
Doug Martin’s custom-assembled Fox .049 FAI is the only engine
being made today that is eligible for 1/2A Nostalgia FF events.
This Russian-made MK-17 .09 diesel is just one of many highquality,
low-cost engines sold by Carlson Engine Imports.
Another unusual model-engine source is Doug Martin, 1510
Locust St., Canon City CO 81212; E-mail: dougsengines@hot
mail.com. He has recently acquired all the existing components for
the 1960s-era Fox .049 FAI FF engine.
Doug is custom-assembling these engines in two versions, one
of which has an engine-mounting tank arrangement on its rear with
the same hole spacing as Cox’s Black Widow. The other version—
the one I have—lacks that tank mount.
The Fox .049 FAI is the only “newly made” engine available
today that is legal for Nostalgia FF competition. And it is a potent
power source for that usage!
It’s true that the original 1/2A Foxes didn’t perform
spectacularly well. But using techniques worked out by Randall
Hopkins a few years ago, the new .049 FAI engines that Doug
Martin is putting together can compete quite equably with Holland
Hornets.
The Fox’s exhaust-port timing is conservative and limits the
engine’s power peak to approximately 19,000 rpm. However, its
high torque at that speed permits using larger (i.e., more efficient)
propellers than a Hornet can swing effectively. And some careful
rounding of the little Fox’s intake-opening edges can boost the top
rpm enough to make the necessary work worthwhile.
Model engines vary tremendously in size, type, power output, and
design. But there’s one thing all those power plants we use for
flying have in common: they require maintenance and repair from
time to time.
In the Good Old Days we did that work ourselves. Our
neighborhood hobby shops usually had most parts in stock for the
more popular brands. For other kinds a phone call to the factory
would quickly bring us what we needed by mail—often for free.
However, those days are long gone. And for some of today’s
model engines, “factory service” isn’t even available anymore.
Nowadays model-engine repair and custom tuning requires the
services of an expert. One I can highly recommend is Bill Jensen of
BJ Model Engine Service. He does the most thorough engine-repair
work of anyone with which I’ve ever done business. Bill doesn’t
work cheap, but his services are well worth what he charges.
Years ago a friend of mine gave me a used, old-model Enya .09
RC engine of the style that came without a muffler and used a
barrel throttle coupled to a pivoting exhaust baffle. I recently
decided to make a custom muffler for this Enya, clean it all up, and
donate it to one of the local youngsters who is just starting out in
RC.
I’ve always enjoyed reliable service from Enyas, and this wellused
.09 still had excellent compression. I had high hopes for it.
Yet after I finished adding the muffler and put the engine on my
test stand, I couldn’t seem to make it run right. “Aha!” I said to
10sig4.QXD 8/24/06 12:40 PM Page 103myself. “This is a job for Bill Jensen!”
I sent the Enya to Bill along with the
propeller I wanted to use (an 8 x 4 Cox
Competition) and information about the
fuel I preferred. This allowed him to set
the engine up for optimum performance
with my choice of propeller and fuel.
The first thing Bill did was to write
one of his detailed Engine Service
Worksheets. On those he lists every step
in his procedures, every item supplied
with the basic engine, and the status of all
the major parts including crank
straightness, compression, and even the
glow plug. From there he checked—and
noted—all the minor (but still vital)
variables that influence the engine’s
performance.
Bill found two small discrepancies on
my Enya. The spraybar had been installed
too deeply and my custom-made muffler
had too much exhaust exit area for
reliable idling.
He corrected those flaws and changed
the glow plug, and after seven separate
test runs between adjustments (each one
noted on page 2 of the worksheet) my
engine achieved a top rpm of 11,900—
and a reliable idle of 2,000!
When I got my Enya .09 back, it was
accompanied by copies of Bill’s
worksheets and copies of Enya’s factory
data sheet and its parts list for my
particular old-style RC engine. That’s
genuine thoroughness—and it’s whyBill’s pricing is higher than most. He simply
does a lot more work than most.

engines.
Just before and after World War II, the
most popular model-airplane engines in the
US were the California-made Ohlssons. Last
manufactured more than 50 years ago, quite
a few are still being used today.
The Ohlssons power old-time FF aircraft,
CL models, and even RC airplanes from the
Good Old Days. SAM (Society of Antique
Modelers) regularly holds events for
Ohlsson-powered airplanes, and they are
well-attended.
Besides the excellence of their original
design, a big reason why these ancient
model engines have survived so long is the
ample supply of newly made spare parts that
my late friend Vic Didelot—a mainstay of
the famous Flying Aces Club—arranged to
have manufactured.
Following Vic’s recent death, his
Ohlsson parts supply was taken over by
Burnis Ray, 6027 Ken Caryl Pl., Littleton

although it seems impossible to me, I’ve
been told that George Tallent in Pichaco,
Arizona, can even remove and replace
