Due to a couple of economic
factors, our products have substantially risen in
value. These factors are as follows:
1. Due to the booming Czech
economy the Czech Crown is advancing against EURO
dollar and Euro dollar is advancing against USD.
This change representing more then 30% increase in
2. Due to the sky-rocketing popularity and
recognition the units have attained a high profile
status, internationally, as well as domestically.
Effective immediately, the MSRP has
been adjusted accordingly. At the current
price structure, WJ units reflect the value in
superior cage/frame design, flight comfort and
leading edge innovation.
Well, some of you may wonder what is going on. The
page is not being updated.... It is simply because
I totally lack time. My other business (the
climbing gym) is still unusually busy and there is
a quite few people who are willing to learn how to
fly PPG therefore I have to leave all the less
important tasks for later. For those who are in
training note that I will be out of country July
15 - 18 and July 23 to Aug 15/05. If you have to
get hold of me you can do so by email.
We used 92 octane pump gas and Mogul 100%
synthetic oil mixed 1:40.
I'm exited about this, because Demo Days is the
largest gathering of PG equipment and pilots in
the USA and it is on the 17-19 of this month. I
hope that we get many manufacturers to show up. I
conduct our own home brewed test here. All
machines willing to participate will get to drink
from the same gas tank, mixed to whatever ratio
they desire with their own oil. There are a lot of
tricks that manufacturers can do to increase
1. Increase the reduction ratio, and let
the Simonini mini 2 plus run at over 8,000 rpm
thus turning the prop much faster
2. mix in avgas with regular gas and pour
in some lead for good measure
3. use a HUGE needle in a Bing carburetor
and let the motor drink like a garden hose.
As you can see, such a motor can be capable of
turning out over 200lb of thrust but it will last
about 1 day. We use stock Simonini with stock
components and the net result is that our motors
last. We do not over stress them, and our props
have a much better dynamic thrust test than
static. As well as the thrust test, we will
conduct highest altitude gain test. Needless to
say, I am exited about our new chromed mufflers.
If you are looking for an upgrade, please send me
an e-mail. If you can make it out to Demo Days,
please send me an e-mail. The trip is worth while.
Stunning scenery, snow covered mountains and good
folks to hang out with. We will have our new Simon
Spider RR on display.

Para stars Report - Thrust Tests
By Milos Krivka
Dave Beresh of Beresh Props did a solid and
un-reputable monitor of the thrust test so that he
could observe the performance of his props.
Testing conditions: Florida. 98% humidity,
Manufacturer - Model
1. Fresh Breeze - Monster
- Zanzoterra - 350cc
- 135 lb
2. Walkerjet - TR, 130 cm prop - Simonini - 202cc
- 128 lb
3. Walkerjet - RR, 125 cm prop - Simonini - 202cc
- 125 lb
4. Fly Products - Gold, 130cm prop - Simonini -
202cc - 121 lb
??? Paralite - Sky Cruiser - Top 80 - 80cc - 88 lb
Once again, we have beat all but the Monster,
which weighs considerably more and has 150cc
advantage. With our new tuned exhaust, generation
5, that produces 8 more lb, we will clean up
quite nicely ! Scoot Cruise had the gen. 4 exhaust
and a Wallbro, that produces less thrust, so
conceivably, we would have won again, had we
introduced gen. 5 muffler earlier in the season.
Last year, we have beat the Monster by 1 lb with a
smaller prop, just goes to show how temperature
and humidity can affect the results. Demo Days in
Utah will prove to be the tie-breaker.
Thanks to Dave Beresh, we have a reliable and
un-tainted results. Dave Beresh is the
manufacturer of some of the best PPG props in the
world. Contrary to some unofficial mumbo jumbo -
nobody got 160lb thrust test. Nobody! The humidity
and high density altitude pretty much pegged

April 11/02. I took the Simon
XC for a couple of short flights as to brake it
in. It was sitting in my shop for 3 months so I
was wondering what is going to take to get it
started. I have mixed the fuel (30:1) poured it
in, pushed the start button and.... the thing just
started to run. I could not believe it. It was so
easy. I have wormed it up, tuned it and took off.
The Simon has more power then Superhawk as I was
climbing at approximately 340 ft min. I have tried
to turn the motor off and re-started in flight
many times and it would always kick in no problem.
It was very nice to be able to soar in the
thermals and all you can hear is the sound of
wind.... If you lose it though, just one push of
the start button will get you back up and you can
try again. I will have to get my self a variometer
as I discovered a new dimension of free flying. It
takes quite skill to be able to stay up just using
the thermals - especially without the variometer.
I have landed after about 30 min and re-checked
the spark plug. It was a little oily as I was
running on the rich side. I have adjusted the high
carb screw and took off for another awesome
flight. After carb adjustment the Simon XC had
even more power and there was almost no vibration
at all. I love this machine. I soon as I sell my
Superhawk I am getting one of these....
Well, today I had a first flight of the season.
The weather was not the best, the field was little
muddy but I could not wait any more. I took off
and flew south bound for about 45 min. The wind
was high at 20 km/h gusting to 25 km/h.
Approximately 12 km from the fields I could feel a
light precipitation and decided to turn
around. It took me only 10 min to get back
as I was flying at close to 60 km/h. The wind got
actually even stronger so I had to use full speed
bar to make it to the lending zone. By the time I
got packed it was dripping. I dropped off a bottle
of Cognac to the owner of the field Joe Zawadski
as a token of appreciation for letting me use his
NEW DHV 2 glider by SKY PARAGLIDERS
whose name comes from Greek word for thunder -
successfully passed the load test and now is
flight-tested in its middle size (BRONTES M).
The first reactions of test pilots are very
positive, claiming that the glider is very “easy
to handle”, has got “excellent flying
stability”, “smooth reactions and still, plenty
of performance which might be used not only for
conventional and occasional flying but also for
And still being mainly DHV 1-2 and 2
rated wing in most flight test regimes. At the
moment the test pilots examine the possibility
of further development of the glider for the
acrobatics enthusiasts and we will keep you
updated about further development.
hope that Brontes will be soon “thundering” all
over mountain slopes and will met arm reaction
of our customers.
