The March Big Sky, Anyone can enter, Informal Soaring Contest


THE MARCH 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 March 1st to 11:59 PM March 31st 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 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

ELECTRIC GLIDER 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. 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.

HAND LAUNCH 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.

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.

Pilot name: Jan
Glider name: Hai 1 Evo - wingspan about 1500 mm
Thermal or slope: slope
Date and Time of flight: 3rd March 2018, 11:00-12:00
Duration of flight: 22:20
Location: Czechia, Liberec

Quite cold (-7 C, about 20 F), very light wind - not strong enough to keep the 1 lb wing in the air, on the other hand this was just good due to low temperature, otherwise a nice sunny day with a lot of thermals (and sinks as well). I went for slope flying and ended up with thermalling. I did fly three flight on 5 seconds motor run, resulting in 22, 9 and 21 minutes.

Thanks, Curtis, for organizing this, and wish long flights to all participants, Jan

After two consecutive days and nights of extreme winds (my anemometer was showing steady 40-ish mph and 50+ gusts yesterday afternoon), it started to get back to normal today. By six this evening, it was downright calm, compared to what we had been experiencing, so I went out for a quick flight just because I could. No significant lift (a couple of blips at 2 to 3 minutes in ) but also no sink, and the prop was obviously getting a good bite on the launch, so...

And I get frustrated with 1 day of "high" winds touching the twenties. It's all relative . . .
Poor Ernie is still waiting for the thaw while the foliage here began budding 2 weeks ago.

Good Morning Curtis

Might be cold & windy here, but we have been flying all Winter long. Mostly just testing and tuning new builds and getting ready for the Woodcrafters event in Muncie, IN. June 1-3.

I've also designed some new funfly contests for the Manville group like LMR 6 minute precision time and distance, LMR MOM double elim thermal and LMR MOM double elim spot landing.

With all that going on I must confess I have not given this contest the effort it deserves, sorry!

Open E Glider Entry


Nice early spring conditions with very little wind, sunshine getting through high thin cloud cover all day... we got in 9 or 10 flights. No real boomers found, but enough here and there on this one flight to log nearly double the time we logged a few days ago. Notice the next flight though, on the chart below... what a letdown!

No improvement on my last flight, but there should have been... I had to bring it down prematurely due to watering eyes and generally bad vision. It's Hell to get old. Notice the spin-down to lose about 400 ft of altitude, 3 minutes after motor cutoff... I had already lost sight of the plane once, decided I needed to be closer to it.

But why am I posting, you ask? Just had to show you what was probably the strongest thermal I've seen hereabouts for quite a while. Add the nominal sink rate of the plane to this, and you've got at least 12 ft/sec air. Only about 50 degrees F, but strong sunshine all day, with this being a 1630 hrs CDT flight. Damned shame it was a wasted piece of air.

I guess I would take heart in the fact that you read the air correctly and launched into a thermal. Nice job!
