Model "B"
blade
The
'B' model is a general
use propeller blade,
although
specifically designed to run on significantly smaller diameters than most
other props. The Model-B runs very well on a 582/2.58 as a three blade
60" for example, and can out-produce our competition even when
running much smaller diameters.
Diameter Range: Minimum: 48" <> Maximum 65"
Speed Range: 22 - 95 knots / 25 - 110 mph
Model
"C"
blade
The
'C' model is
designed specifically for powered parachutes as a three blade 64" on
a Rotax 582/2.58. This design works well on Rotax 447's through Rotax 618
as well as the Hirth engines that fall between 40 and 80 horsepower. This
has been the propeller being sold as standard equipment on 6 of the top 7
PPC's.
Diameter Range: Minimum: 48" <> Maximum 65"
Speed Range: upto 31-knots / 35-mph
Model
"E"
blade
The
'E' model is
our smallest, narrowest propeller blade - designed for engines between 15 and 30
horsepower. Backpack & PPC's are the target of this design although the
blade has been proven very efficient on many older, fixed wing airplanes
with diameter restrictions. This is the ONLY pitch adjustable prop
available to backpack units.
Diameter Range: Minimum: 39" <> Maximum 53"
Speed Range: 20 - 70 knots / 22 - 80 mph
Model
"F"
blade
The
'F' model
is our largest propeller - designed for larger two-stroke engines that use
the higher gear reduction ratios and horsepower up to 115. This prop blade
runs beautifully on a Rotax 503/3.47 as a three blade 66" to
70". A two place Kolb can't squeeze any more efficiency out of
a 503/3.47 than with our F-model 68" prop. This prop is also the
finest prop available for the Rotax 912, 912S, and 914 engines.
Diameter Range: Minimum: 48" <> Maximum 75"
Speed Range: 22 - 95 knots / 25 - 110 mph
Something
Else To Note
These
recommendations are for the largest possible propeller blade that is
aerodynamically suitable for the engine and reduction gearbox combinations
listed.
*The LARGEST possible choice will generally give you the best
performance in the static and climb mode of operation.*
Most Ultralight/LSA
class aircraft fit into this category.
If you have an airplane (fix-wing)
that goes faster than the average Ultralight, you might want to run a
smaller diameter than this list recommends. It would be best to contact us (Email us) if
you have the slightest question about this.
Which
Direction? The direction of spin...
Direction
of rotation is always noted from the REAR
of the vehicle. If you are standing behind the aircraft and getting blown
by the prop wash, which direction is it turning?
Counter-clockwise
is a LEFT turning
prop and a clockwise is a
RIGHT turning
prop.
The
following is a fail safe list to follow for rotation direction.
TWO-STROKES
For
all TWO-STROKE engines normally used with Ultralight/LSA:
-
PUSHERS
with GEAR-boxes run a RIGHT turning
prop
-
PUSHERS
with BELT-drives run a LEFT turning
prop
-
TRACTORS
with GEAR-boxes
run a LEFT turning prop
-
TRACTORS
with
BELT-drives
run a RIGHT turning prop
FOUR-STROKES
The
FOUR-STROKE
engines (912, 912S & 914)
turn
opposite the two-stokes and are only available with GEAR-boxes...
-
PUSHERS
run a LEFT turning prop
-
TRACTORS
run
a RIGHT turning prop
