Rainer and Barbara Friebose are
a friendly couple, nice folks,
who have taken up residence in
South Africa, along with their
aircraft called a Samba. They
are from Germany, where the
tradition of gliding is
super-strong, and spent eight
years from 1991, as motorised
nomads, wandering in a leisurely
way through Africa to get here.
Quite an experience no doubt,
but having arrived and being
"flying-people" thoughts turned
to enterprise.
The
enterprise has developed into
Wings 'n Tracks, run by Rainer
and Barabra and the distributor
for the Samba and its (more
glider-like) brother the Lambada,
in SA. Having seen the Samba at
the Fridrichshafen Airshow in
Germany, where many new and
innovative designs are shown,
Rainer decided that this was
just what SA needs and wants,
and procured the
distributorship, bought the demo
machine and brought it into SA.
At
the first opportunity, Fly South
grabbed the chance to have a
close look and to fly the Samba
and we met the couple at their
base of operations, Brits
Airfield.
First impressions count and the
impression that the Samba gives
is that of a smallish light
aircraft with some striking
differences. The styling is to
our eyes, not of an American
flavour and is certainly not
unattractive. The construction
and finish externally is all
composite of a very high
quality, with not a rivet or
protuberance in sight on the
wings or fuselage. The big
bubble canopy promises excellent
visibility, and it's dimensions
indicate a fairly roomy cockpit
for two people.
Wheels are faired, as are the
nose and maingear legs and the
wheels are large - Rainer
confirmed that these are the
standard wheel, but with tyres
fitted that are more suited to
Africa than those supplied
originally. The new tyres have a
deep, knobbly tread, more able
to handle sharp stones and
thorns without punctures than
the original thin-skinned stock
tyres. All Sambas sold here will
have the heavy duty tyres.
With the one-piece cowling
quickly removed with the twist
of a few Dzus fasteners, the
engine installation, a Rotax 912
of 100 hp was revealed in all
it's glory. A neat and tidy
installation, with one essential
mod that Rainer has added - a
backup electric fuel pump to
take over should the mechanical
pump ever quit, always a
definite "nice to have", as
anyone who has ever had a
mechanical pump "go awol", can
attest!
Turning at over 5000 rpm at max.
the little Rotax (only 1300cc)
pumps out it's 100 ponies via a
neat gearbox, and this is how
1300cc can make an airplane fly
- whilst a gearbox won't
multiply horsepower, it most
certainly can and does multiply
torque - and as we all know
torque is what will get you off
the ground!
Lifting the canopy up and back
on it's rails for an examination
of the cockpit showed two
built-in seat pans with thin
cushions - comfy enough for most
flights, but for a flight the
distance of which the aircraft
is capable, over 1000km or
1500km with optional tankage, I
would take an extra cushion or
two. Behind the seats, and soon
to be closed in with a
quickly-removable cover is the
tunnel of the rear fuselage
leading to the tail, almost
unobstructed save for the
battery sitting back there.
There are plans to make this
space available for
transportation of items such as
fishing rods, golf clubs etc.
The
panel is neatly laid out and
features electronic, digital
instrumentation in the form of a
Flydat panel which gives all
engine information, including
EGT, CHT, oil temp, oil
pressure, water temp and more -
very nice.
After wheeling the aircraft out
easily from the hangar, we
clambered in and strapped
ourselves to the machine with
4-way harnesses. Startup held no
complexities and the engine
instantly settled into a 1300
rpm smooth and quiet idle - the
rpm indicator give engine rpm -
just divide by the gear ratio of
2 (to 1) to know how fast the
prop is turning.
Steering on the ground is
accomplished using the rudder
pedals linked to the steerable
nosewheel - pressures are light
and steering simplicity itself -
brakes are only available on the
pilots's (left-hand seat) side,
and consist of a single
"bicycle" type lever operating
through a hydraulic cylinder.
Since I was doing my thing from
the right hand seat, Rainer
handled the braking duties.
Once turned around and facing
the correct direction at the
threshold, we had to wait a
while with the engine idling, as
temps came up - this delay
largely due to the fact that the
relocated oil cooler, on a cool
day as we had for the flight, is
exchanging the heat efficiently
and unlike an air-cooled motor,
it is essential to get the temps
up before putting power on, for
the sake of the engines'
longevity. No great hardship
however as with a couple of
minutes the temps had reached
the magic number and we were
ready to go, after run-up and
vital actions, which included
setting one notch (half) flap
for take-off.
With the relatively large amount
of horsepower for the aircraft
weight, the Samba exhibits a
decided tendency to swing on
initial application of power,
before the rudder bites. Once
air is flowing over control
surfaces, and that seemed to be
a very short time, we were about
ready to lift off - with less
than 100 metres in total we were
airborne and climbing strongly
at just under 2000 fpm and
between 50 - 60 kts indicated!
Very impressive and with a good
amount of TSF (That Solid Feel).
Noise levels at max available
rpm of 5400 were moderate and
conversation was easily possible
without headsets and intercom,
during the climb.
Levelling off the aircraft
accelerated quickly and would no
doubt have kept accelerating to
it's claimed 90 kts cruise or
115 kts top speed, but we were
there more to explore how it
flew, rather than ultimately how
fast.
With power reduced to around
4400 engine rpm (2200 prop rpm)
we were wafting along at 60 kts
and exploring turns and general
handling - at all times the
Samba likes to climb, testament
to it's excellent aerodynamics.
All controls are powerful, light
and responsive - unexpectedly,
given the 10 metre wingspan,
roll rate and response is
excellent. For the size of
aircraft and it's fairly
short-coupled configuration,
longitudinal stability is good.
During turns a touch of rudder
is needed - unlike many modern
aircraft which can be flown with
virtually no rudder input in
normal turns to keep the ball in
the centre, the Samba prefers
that your feet remain on duty,
just to keep everything nicely
balanced.
