The august big sky international soaring contest

THE AUGUST BIG SKY INTERNATIONAL
LONGEST DURATION CONTEST FOR ALL ELECTRIC AND HAND LAUNCHED GLIDERS
THERMAL SOARING AND SLOPE SOARING
RULES AND INFO:
Contest will run from 12:01 am August 1 to 11:59 PM August 31 Eastern US time.
The contest is for ALL electric or hand launched gliders or airplanes of all sizes, all materials and all controls. The contest is intended to help motivate you to develop your thermal and slope soaring skills.
The contest is open to all gliders, e-gliders and, if you like, e-airplanes too. If it glides, it qualifies.
In Thermal Duration, the contest is split into three classifications, 2-meter and under E Gliders, Open class E Gliders and Hand Launch Gliders.
You can post as many times as you like using as many planes as you like, but only one will be counted per pilot per category regardless of what kind of plane you are flying. You can replace a shorter time with a longer time any point during the contest. You can fly as many flights as you like.
Goal - longest duration thermal and slope flights without use of the motor.
THE PLANES:
* Any electric motor system or unpowered hand launch glider. (No winches or Hi-Starts).
* Any wing controls and any wing span
* Any construction
BIG SKY - ELECTRIC THERMAL SOARING
1) From a fresh hand or ground launch you can run the motor for up to 30 seconds, then you turn the motor off and you can not restart it. Reclimbs are not permitted. If you restart the motor the flight time is no good.
2) Motor time starts as soon as you apply throttle. This is an LMR, Limited Motor Run contest with a pretty long motor run allowed so that the motor run itself does not provide much advantage to anyone. Many will choose to shut off the motor in less than 30 seconds. No credit for shorter motor runs.
3) Soaring time starts when the motor goes off. Either you time the whole flight and subtract the motor run or you use two watches, one to time the motor run and one to time the flight. I have multiple timers on my radio so I can do this with my radio alone. How you do this is up to you.
4) You can time your own flight if you wish. You are on your honor. Time is truncated to the second. No fractions and no rounding. Read the seconds only.
5) Landing must be within 100 feet of the original launch location or the flight does not count. Landing must be on the ground/grass or pavement. Landing in a tree, bush, structure or other elevated spot that would not normally be a landing spot does not count. There are no other rules around the landing.
6) Time stops when the glider comes to a rest. So the clock keeps running if you clip a branch, or go to land and bounce back into the air. When the plane stops, time stops.
7) You can launch as many times as you like but each flight has to be from a fresh launch from the ground/hand. No reclimbs permitted.
8) Report your best time of the day by posting here. You can post as many times as you like, but only the best one will count. You can fly as many days as you like to work toward your best time. The goal is to achieve personal bests in the fun atmosphere of a contest.
BIG SKY - HAND LAUNCH THERMAL SOARING
1) Soaring time starts at release of the plane.
2) You can time your own flight if you wish. You are on your honor. Time is truncated to the second. No fractions and no rounding. Read the seconds only.
5) Landing must be within 100 feet of the original launch location or the flight does not count. Landing must be hand catch or on the ground/grass or pavement. Landing in a tree, bush, structure or other elevated spot that would not normally be a landing spot does not count. There are no other rules around the landing.
6) Time stops when the glider comes to a rest. So the clock keeps running if you clip a branch, or go to land and bounce back into the air. When the plane stops, time stops.
7) You can launch as many times as you like but each flight has to be from a fresh launch.
8) Report your best time of the day by posting here. You can post as many times as you like, but only the best one will count. You can fly as many days as you like to work toward your best time. The goal is to achieve personal bests in the fun atmosphere of a contest.
BIG SKY - SLOPE SOARING
1) From a fresh hand or ground launch you can run the motor for up to 5 seconds, if you need it to get into the lift. I would expect most slope flights will have no motor run but some sites need a boost to the lift.
2) Motor time starts as soon as you apply throttle and is subtracted from the total flight time.
3) Soaring time starts when the motor goes off. Either you time the whole flight and subtract the motor run or you use two watches, one to time the motor run and one to time the flight. How you do this is up to you.
4) You can time your own flight if you wish. You are on your honor. Time is truncated to the second. No fractions and no rounding. Read the seconds only.
5) Landing has to be within 100 feet of the original launch location or the flight does not count. Landing must be on the same level as the launch. Landing down the slope or up in the trees does not count. You must come to rest in a "normal" landing spot and be able to walk over and pick it up. I realize this can vary by slope site so you are on your honor as to whether this was a normal landing.
6) Time stops when the glider comes to a rest. So the clock keeps running if you clip a branch, or go to land and bounce back into the air. When the plane stops, time stops.
7) You can launch as many times as you like but each flight has to be from a fresh launch from the ground or hand. No powered reclimbs permitted. If you restart the motor the flight does not count.
8) Report your best time of the day by posting here. You can post as many times as you like, but only the best one will count. Try as many days as you like to get your best time of the month.
For either contest you report the results via post.

Since I'm new I'll start things off. Since I won't be able to match the better flight times until I get some bigger batteries this will probably be my only chance to lead.

I could have made it longer if I hadn't gotten a bit overwrought bailing out of a monster thermal. At least I know how fast I can go without folding the wings!

Went to the beach for the weekend - packed my 'beater' DLG and managed to get some flying in on Sunday AM. This is my first 'real' slope flight - more like skimming the dunes. Here in eastern NC it's flat, flat, flat - so thermalling is the name of the game. I have often thought about sloping the dunes and I finally did it!
What a blast! There was a stiff breeze off the Atlantic, right up the dunes - the dunes are not really high, maybe 10 - 15 feet after a small rise. It took a couple of tosses to figure out where and how big the lift band was (not much, not very high, but once known it was very flyable. I never got higher than maybe 30 feet, but it was consistent, and if I got pushed back too far, I was always able to reach the lift zone again and climb a bit...

Time to build a micro sloper for the beach!

Location: Greenville, NC - USA

I have been working on this project for some time - scratchbuilding a capable flying/soaring wing. The first step in this process is the Horten III. It got built in the winter and maidened in March.
It has been quite a handful to tame - I had problems with aileron flutter, so I learned how to do silicon hinges. I had too much incidence on the motor thrust line - that's fixed now. It really took a long tim eto figure out the proper CG location - wings are extremely sensitive... I also underestimated the amount of washout needed - so now the ailevators are making up for that deficiency. In any case, it finally flies 'hands-off'
Don't think I'll 'win' but I feel that I won by getting this design this far!

I also invested in a altitude recording device, so I was able to document my flights.

The last issue I have is that the folding prop in the pusher config does not always fold (weak brake?) when it does not, the HoIII really comes down like a brick. When it folds, decent performance and thermalling is possible - see flights 2 & 3.

Anyone have any experience with pusher folding props?

Glider: Art Hobby Orion 2.5 Meter
Thermal
Date and Time of flight: August 5th, 2012 11:00am
Duration of flight: 8:40 (after 30 sec motor run)
Location: Paul Bunyan Flying Club field - Brainerd, Minnesota
Max Altitude: 1078 AGL
Weather Conditions: 74 degrees and a nasty 12 mph wind made soaring (and landing) a challenge!

Thermal conditions have been poor here for the last few weeks and I'm looking forward to the fall when things should improve.

Martin,
Beautiful scratch built wing! Are the plans available for download somewhere?

Blunight - sorry no plans that I know of, however there are several Horten projects going on, so someone else may know of one.
I don't think that this version really merits sharing yet - next one is going to be balsa sheeted foam with - hopefully - better performance & larger too.

Max Altitude: 2000 ft?

It was an unusual thermal day today, all the lift seemed to be above 600-700 feet or so. I spent an hour throwing my DLG with no luck finding lower thermals a poor hand catch crunched the boom putting an end to my DLG flights for a while.

I put up the Orion and had no problems finding lift at the top of the motor run lots of flights in the 10 to 20 mn range. At one point I had my spoilerons out for a good 2 mns trying to loose altitude!
My altimeter battery was DOA when I quit flying for the day, I'll post the plot later if it recorded.

You almost beat me, blunight, but not quite! Don't worry if you improve though because I cut fellow Minnowsnowtans a bit of slack re: grudges. It's a bit amusing that we from the frozen tundra are ahead of all those guys from desert-like environments.

Outstanding! The only thing better than being beaten by a neighbor from the frozen north would be flying togeather some day.
