BTW since the fly in we have day after day of PERFECT, calm, mild East Cape winter weather. We were one week too early!

Two days to go & our aerie’s sick
For the last 3 weeks all we’ve got from her are coughs & grunts.
The grease doctor rules out flu; she hasn’t got a temperature!
We’ve replaced coil, plugs, leads, had the electronics tested and stripped the carbs,
Cleaned the jets, checked fuel flow & set the timing to the e-manual – eish!.
All we’ve been rewarded with are farts and backfires. So much for DIY.
It’s hard to get a good, busy mechanic to drive to the sticks to look at a modified engine
that was never sold in this country – and then tell him it’s in an aeroplane!
He suspects timing – women are all the same & Skattebol’s no different.
Ignoring the manual, he adjusts the cams manually; The unusual firing order
Of 1,3,2,4 seems wrong, but what the hang, nothing else has worked & we’re
Resigned to driving the 1000km to Paradise Beach anyway.
The first Whisper Fly-in EVER – and to make it worse, it was my idea.
Try it again, quarter throttle and one prime shouts Jens.
A rattle & she bursts into life – I can hardly believe it!
The manual doesn’t say Subaru EA-82’s timing is referenced 90 deg from TDC & our
modified flywheel markings didn’t help much either. Lesson learnt.

TV weather predicts 60% rain over most of the route south. Durban Met disagree, tossing us a tailwind for good measure.
Wednesday dawned bright & clear & saw us topping up the tank.
One last Thermos coffee (more on that later) & off we went, climbing out to 6500.
The Southern Berg is stunning, bathed in reds & browns from the low sun.
Bushmans Nek and Sehlabathini, guarding the Malutis, drifted past, reminding me of some awesome trail running, and an overnight in the Lesotho Kings’ hunting lodge.
Kokstad’s surrounding mountains rose up ahead & we climbed to 8500, ensuring safe passage.
The initial excitement matured into the routine of a long cross country.
The Whisper is extremely comfortable, seated in a semi-prone, “Lazy-Boy” lounger
arrangement & we were enjoying the prospect of a few days in Paradise when it happened!
I’ve got to go!
What do you mean?
I need a pit stop
No way, we’re 90 minutes to Bulembu - hold it in!
Can’t
I’m not stopping here
Come on, finish that water bottle
Now this is where it gets interesting, as we don’t have a window. Anyway, water drunk & bottle empty I hand it over for the performance.
Visualise this…gravity laws suggest fluid is routed downwards; anatomy, while seated, directs flow upwards. Amid much hilarity Carl was relieved and all went well.

Over Stutterheim, and Bulembo in sight, we call East London to request descent.
There was moderate turbulence over the Amatolas & I throttled back a bit to ease the ride in, once again remembering last year’s trail run there; the best 105km in the country – period.
Bulembu (Bisho) was built for 747’s; 2500mt of pristine tarmac, used only by 43 Air School, flying mostly 4 seaters.
Albino elephants come to mind - not even an approach control in the deserted tower.
A pie & a looong pit stop later Russell calls me for a perfect weather update –
Top up the tank & we’re on our way again.
Following a Yak, we do the runups; 4000RPM for at least 20seconds, temps & press good, AOK.
Backtrack Forever, call “rolling” & up we go. In the air 5 sec & the engine quits ???
I’ve been down this road before…nose down, cycle the throttle, and…nothing!
Speed good, lots of runway ahead, spoilers out & a normal gliding “cable break” straight ahead landing.
Now, if you are tiring of my ramblings, please, please take only the following away with you…..
We are very careful when filling & normally filter everything with a good quality device that even removes water from fuel – except we didn’t use it this time! Fuel pipe blocked before the first in-line filter. Take some advise & fit a finger strainer to your tank, it will be the best R100 of insurance you ever spent. Just do it! Dirt WILL get into your tank. The filter WILL prevent it blocking the pipe. This is a very common cause of engine failure. Lesson learnt.
Port Elizabeth, Echo Mike Tango airborne Bulembo at 1215, overhead Grahamstown and maintaining 4500, requesting a low level coastal routing to Paradise Beach.
Echo Mile Tango, what is your speed?
130KPH, I’m sorry sir, we can’t go any faster!
OK
2 min later…Echo Mike Tango, can you give us your speed in knots?
Standby…
Do you know the conversion?
No….. what do we tell them?
Thank goodness for a GPS with unit conversions (divide KPH by 1.853).
I'm sure they'll use this in an ATC training manual sometime in the future. Lesson learnt.

1500 over Uitenhague & around Progress Airfield with some Jabis doing circuits, we intersected the coast just south of the city & were released by PE Approach overhead the Gamtoos River – awesome, first time ever in our own aerie over the dunes.

Over St Francis Bay

Above the Chokka boats & St Francis Bay, on to Cape St Francis lighthouse, we didn’t want to land; wanted to hold the moment a little longer, drinking in the peaceful late afternoon atmosphere.
What an adventure, our Whisper returning to her birthplace.


OK, OK - enough of this - sheesh, it's only a flip down the coast!
Should I go on? - you tell me?...

Footnote - ALL other Whispers are much faster than ours - we're just scared flying faster!

Re: Why we run Jabi's

Post by PeterB » Fri May 15, 2009 4:07 pm

Mr Dave.
Nice posting.
By the way this is just one of the reasons that we run Jabiru's!!!!!!!!!!!!!!!!



11 FUEL SUPPLY SYSTEM
11.1 Fuel Tank
The fuel tank must be fitted with an outlet strainer of between 8 and 16 mesh per inch, with a
minimum total mesh area of 5 cm2.
11.2 Fuel Filtration
A Fuel filter capable of preventing the passage of particles larger than 0.1mm (100um) must
be installed between the fuel tank outlet and the fuel pump.
The filter must be present in the system for the fuel flow test. The size of the filter should
give consideration to allow adequate flow with a used filter.
A Ryco Z15 or similar filter has been used successfully.
11.3 Mechanical Fuel Pump
The mechanical fuel pump is mounted on the engine crankcase and is camshaft driven. It is
designed to supply fuel at the pressure described in the following paragraph. To prevent fuel
vaporization in the fuel pump a small amount of air directed onto the pump is advised,
especially when using MOGAS. Electric Boost Pump must also be capable of no more than
3lb pressure.

Hey Peter

Thanks for the info...it is in the process of being implemented
The good thing about a story is that you can choose what to include.
We have 2 filters, a gascolator and 2 pumps in our system
AND we filter (nearly) everything that goes in & still got stung!
Initially, I was going leave the Bisho bit out. Why advertise your shortcomings?
Then again, an interesting adrenaline shot could have a different outcome.
I hope some other builder out there takes note & our sport is a bit safer
because of this.

Jabis are fantastic engines - I love their simplicity, compactness & low weight
No cam belts, no radiator, dual ignition, direct drive...
I think the 2200 is one of the best powerplant options for a Whisper, however...
I can dream of flying a Whisper with a Jabi, or I can actually fly a Whisper
with a SuBuRu - a wonderful alternative that I need to get to know better.

Cheers

You and Carl are legends Bru
Building a Whisper from scratch with a rally car motor 8)
Awesome

Looking forward to the next fly in in KZN

Keep up the good work

We’ve actually done some rallying ourselves…
A single stage event, about 10 seconds duration, terminated abruptly in long grass.
I think the Zimmower beat us somewhat, in that the ramp jump
Actually achieved some altitude and distance.
Our grass cutting skills were also not quite as refined – or spectacular !

Talking of Rallying.....

My sources tell me that a Whisper placed second in the prestigious annual Ritchie Rally held in PE.
Apparently our man PeterB is responsible for this :D
How about some pics of you holding the silverware Pete!
