Planes for Radial Engines?

While looking at the standard engine manufacturers, like Saito and
O.S., catalogs I notice that they make spiffy radial engines, but I
never see models specifically designed for them. Do any exist? Do
these actually work well, or do they just gobble fuel and weigh more
than a model engine should? I have seen an 8 year old Saito 3-Cylinder
on a test stand, but the guy still has not built a plane for it in all
this time.

Re: Planes for Radial Engines?

I've seen a 3 cyl Saito in a Piper Cub and it flew nice with oodles of
power. I saw a Siedel, 7 Cyl I think, on a flying boat... quite impressive!
From what I've seen they work very well.

Re: Planes for Radial Engines?

There are plenty of planes that can use the radial engines. I saw a Byrons
Wildcat with a Saito 5 cylinder in it. Looked grear, sounded great and flew
great. You can check out Ziroli, Vailly and Brian Taylor plans for some
ideas.

Re: Planes for Radial Engines?

Club member has a 7 cylinder Seidel in a Proctor "Neuport" which he took to
USA in 97 or 98 and came home with several prizes from the scale
competition.- A tad out of scale in the horse power developed as model takes
off and flies under 1/3 throttle, whereas the pilot of the full sized
aircraft was always seeking more throttle..
Several twins in almost daily use.

Re: Planes for Radial Engines?

I would like to find a good excuse to buy one of RCS's 5-cylinder,
four-stroke, gas/oil engines.

Maybe a Gee Bee? All it would need is an electric starter.

Anything whose full-scale counterpart was designed with a radial
engine would make a good candidate for one of those radial engines.
Planes generally aren't designed with a specific engine in mind. Even
if they are, the individual modeler can use whatever engine is
appropriate for the airframe (or even some that aren't . In other
words, anything with a round cowl.

Radial-engined scale subjects with their short noses normally need a
bunch of ballast at the front to balance, so it's a win-win situation.
You get the sound of a radial, and useful weight instead of a bunch of
lead.

With the hefty price tags on these engines, it's pretty easy to see
why you don't see them or appropriate airframes prominently advertised
much. Only people with serious money to burn actually buy them; most
of the rest of us just drool on them and kick the tires. Do you know
how hard it is to get drool out of the cooling fins on an engine?

Re: Planes for Radial Engines?

A club member put a Seidel radial on a 1/4 scale "Spirit of St. Louis." He
said it had lots of power, but was so weighty that it raised the wing
loading to undersirable levels. Lots of power does not mean it is the right
engine for any plane. You must match the engine to the airplane so the
power, wing loading and flight characteristics are correct for the airframe.
A heavy radial may be best with a plane with lots of wing are that flies in
a scale manner. You can't put on on a Balsa USA Nieuport 11 and expect it
to fly like a 3D aerobatic plane. Matching engine to airframe is not easy.
If doem correctly, it will enhance your experience with the airplane.
Good luck,
Mike

Re: Planes for Radial Engines?

Totally agree, My 5 cyl weighs in at 6.5 lbs and at 4hp thats a lot to carry
on the front for the given power. An experienced scale modeller advised on
the Avro 504 cos it has lots of wing area and will fly in a sacale manner
with my particular motor. No 1/3 scale Sukhoi SU26's cos although the motor
would fit, the weight of the balanced model would be to much for the motor
to perform the aeros required. Shame though! When some one does a light
weight radial I want one!! A large DH Beaver would be nice!

One of the best scale modellers in the country uses radials in most of
his planes. Charlie Nelson first buys the engine, and then he designs
a plane to fit. His Wacos are something to see. His latest uses a
Siedel engine. Hearing it run is itself an experience.
