San Valeer's 2000 Annual
by T. Thorkildsen

We were all looking forward to our annual and we had some great prizes to
give away and the weather forecast looked good with no storms on the horizon.
We weren't disappointed since this year we were blessed with good weather and a
great turnout at Taft. We had 61 contestants that flew 200 events.
The event was even published in the local Taft newspaper “Daily Midway
Driller” with a full-page picture layout showing pictures from Saturday’s events.
Gus Sunberg was instrumental in making this happen, thanks Gus.
Saturday we started off with the cannon ball run for the two longest flights on
a 7-sec motor run. Guy Mennano did the deed with 712 seconds flying one of his
Booh models winning $25 for his effort. Guy also won Ralph Prey’s award for the
highest time flown by the designer of the model with a Booh II in another event.
In the FAI events we had maxouts in both F1A and F1B with Bill Booth Jr.
winning F1B over Alexander Andriukov who stumbled on his last flight. Martyn
Cowley and Lee Hines tied in F1A being clean in all 7 rounds.
The regular events started at 8:00 am and after a long day of flying 1/2A gas
was won by Mike Ryan flying a new Cyclone .049 powered Orbiteer with 13+
maxes for a new Cat 2 record. He was one happy camper. Congratulations Mike,
it was really your weekend! His model was 370 sq inches and how many TD’s do
you know that can haul that size of an airframe up? With these motors you can
build a scaled down A job and do well with something that is easier to see then a
normal 1/2A. Bob Sundberg had good time in this event also dropping his 5th max
with Robert DeShields 3rd flying a TD powered Tornado. We had 2 Juniors flying
1/2A, and both Tyler Secor and Jared Jacobs had good times and in fact Tyler
dropped his 6th flight by only 10 seconds which would have put him in 2nd place in
the open event. He comes from a great modeling family and with Al Hotard being
his grandfather and Randy Secor being his father it is hard to miss and this kid has
the talent to go a long ways in the hobby.
For a change we had no maxouts in 1/2A Nostalgia since we were flying the
Cat 2 (ALT) rules with the shorter motor rules which most of us on the West Coast
prefer for cat 2 and cat 1. Norm Peterson won it winning a Top Banana short kit
and Cox medallion motor flying a Geef with a medallion. Gus Sunberg was 2nd
flying a Fox FAI .049 powered Green Hornet a great combo. It is good to see those
Fox motors since they are readily available from H & R motors and they make good
power with a large prop.
We had a good duel in B gas with Guy Menanno with a Nelson .21 powered
Booh edging out Terry Ellington with a ST.29 powered Duster when they both
dropped their 5th flights. Terry Ellington has improved his flying skills a lot over the
last couple of years.
In C gas Kerger’s Hoffield powered Archer satellite put up 4 maxes for the
win and he didn’t have to continue on. Ellington was 2nd dropping his 4th max flying
a Crusader. Roger Coleman was 3rd and was clean until his 3rd flight when it
appeared like he ran out of fuel a second or two after the launch, a tough break for
At noon on Saturday Lynn Pulley offered to spell me from the table and I got
to fly Slow gas for about an hour which was a nice break. Mike Ryan and myself
were the only ones to max out of the 7 flyers.
Tony Robertson who I grew up with, but hadn’t seen for at least 30 years,
won F1J over some tight competition from 7 other contestants with his own original
with an AME .061. We used to fly planes together in my back yard when we were
kids. We flew anything from 1/2A combat models to hand launch gliders to Jetex to
small gas models. If you tried that now you would be flying in the middle of an
asphalt parking lot with condos. Anyway his model was flying great with bunt and all
and he edged out Kerger to win an AME .049 and an Astrostar short kit.
Saturday it was a little windy later in the day at about 4 to 9 mph but certainly
flyable but Sunday we woke up to a classic Taft day with not much in the way of
wind at all, and it was great the rest of the day.
I started out with a flyoff in slow gas but Mike Ryan pulled 8 seconds ahead
of the time I had on my ST .19 powered Jupiter to win a CS .09 for his efforts.
The Bob Hunter memorial was going full blast at this point and I just had
enough time to put up one flight with my Astrostar 600. This event is for the longest
flight on a 15 second motor flown between sunrise to 1 hr after. I had an 11:31
flight for the win with Guy Menanno next at 9+ minutes. We had 7 flyers in this and
Steve Moffat also gave us a donation. This is for a good cause since all entry fees
in this event are given to the heart foundation.
After that I then put up 5 quick flights in A gas before I came back to work
the table but with 10 entries it didn’t take very long for 3 guys to shoot right on by
me with Wes Funk first with 6 maxes winning a ST 40 for his efforts. He was
closely followed by Mike Thompson and Guy Menanno who both dropped their 6th
We had 9 entries in Catapult with Martyn Cowley winning with 4+ maxes
winning a Big Mig .049 and a stop watch for his efforts edging out Moody,
DeShields and Hines who are all great glider fliers. We had 3 Junior fliers and
Tasha Duncan won 1st with 102 seconds closely followed by Jeffery Gannon at 99
seconds which certainly made him happy. In HLG the names were the same just in
a different order with DeShields winning it this time.
We had the most entries in P-30 with 13 contestants with Bob White scoring
the win with his Twin Fin II. Bill Booth Jr also maxed out but dropped his next flight
big time for 2nd. Jeffery Gannon one of our Juniors had a maxout also to sweep the
junior event. Good flying Jeff! We gave a pound of Tan II rubber that was donated
by FAI supply to a lot of the winning rubber flyers.
Coupe was won by a Bob Van Nest with 7 maxes with a minute added to
each flight after the 5th max. He was closely followed by Jeffrey’s father Bill
Gannon who stopped at the 6th max. Clarence Mather and Don Bartick both got up
to their 6th flight before dropping the max in Mulvihill and they are both really nice
guys to boot.
ABC Nostalgia had a good turn out with 9 contestants and Mike Thompson
won it with 5 Maxes closely followed by Jack Moreland who dropped his 5th flight.
They were both using a pair of good flying Ramrods.
After a great weekend of flying we handed out some great prizes and had a
free raffle for a K & B 3.5. Guess who won the raffle? You guess it Mike Ryan.
With the luck he had going I hope he bought some lottery tickets because I don’t
see how he could have missed.
I want to thank everyone that helped me run the table and/or donated prizes
like Bill Kuykendall, Steve Moffat, Lynn Pulley, Jim Hurst , Lee and Lois Hunt, Bob
DeShields, Mike Thompson, Ralph Prey, Lou Delia, Doc Faucett, Guy Menanno,
and Norm Peterson. A special thanks to Dick Zackman who donated a K & B 3.5
for the free Raffle. I apologize if I forgot anyone.
A special thanks to FAI supply who gave us all that great rubber and a
bunch of other stuff. Their web site is We also want to
thank MRL and Aerospace composite products. Be sure to support them since
they support us.
I hope everyone returns next year for our next annual where you can expect
a fun filled weekend with good competition and some great merchandise that you
can use. The results and some pictures will be in this issue but we will probably
carry some of the pictures to the next issue since we have a bunch of them.

Brian , North Dakota:
PO BOX 366
Sayre PA 18840-0366
sells Harlan strippers and a few other indoor items.



the harlan strippers let you make the rubber strip different widths. This
is how you tune the model for diffeent size [height] halls. By making
the rubber thinner it does not have so much power so the model will not
climb and hit the roof. If it is too thin in will just cruise at low altitude
and come down too soon.]

<< Now my question.At what angle 8.5"[215mm] from center line should we start
with for the low end of a VP prop?>>

I do what Alex Andriukov suggested and I think most others do similar.
Take the Nominal pitch that you would normally use at that point and then
Add 6.0 degs for the start of the climb and subtract 6.0 degs for the low
pitch point. ie 12 degs from High to Low pitch. NB I still feel there
may be a case to be made for increasing the pitch again towards the end of
the run but that is a very personal and as yet, unproven theory based on some
simulation work I did with Ian Kaynes.


Normally it is but this may not be the full answer (??)


I guess the way to look at it is this. As the pitch is directly
determined by the torque, which should equally determine the climb speed and
angle, The VP should be set up the same for both. The prop will work out
what pitch it should be at, depending on what the torque is. However this
is not to say there are not other factors that may play a part, (Inertia of
the model etc.). We are forced to say we still do not understand
everything about the effects so, It is conceivable that things like the
setting up of VP for different motor configurations may still need to be
understood more fully.

I hope this helps a little or, at least will open up more debate on the

Your's respectfully
