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


THE APRIL 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 April 1st to 11:59 PM April 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.

Open E Glider Entry


The wind died down from 18-20 mph earlier, so I went out and managed 3 launches late in the day. The first flight was my best of the 3, despite the fact that the 2nd flight looked very promising right after launch (see chart).

With rain and snow showers predicted today and generally windy weather after that, it will most likely be several days before I get another realistic chance to fly.

I stopped at our local field on the way back home from work. A sunny day with some wind up to 4 m/s, with a lot of small and short lasting bubbles. I practiced low flying with max. 10 seconds climbs and 2-7 minutes flight times. Eventually IT came! In about 6th minute Solius reached the ceiling of my comfort zone and I flew to the other corner of the sky and started to descent - it took another 11 minutes :-) .

Happy thermaling to you, guys,

Another early evening flight that paid off. We had moderately strong lift over a fairly large section... until there wasn't.

Well, I knew it was too good to last, one 70 day and just like that we're back in the chilly windy Spring weather pattern. Rats!

I am using a device for ALES which turns the motor off a predetermined altitude ( 200 meters) or after 30 seconds.

I did maybe 10 flights of about 2-5 minutes (after 7-10 s of motor run) and thought it too late for any substantial thermal. I almost decided to go home when a buzzard appeared nearby. So I flew directly to him - they are never mistaken, these birds.

Oh, sorry, Roger and AMA, but 21:48 was on my stopwatch :-)

Happy thermaling to you, guys,

A beautiful Sunday, clear sky, 26 C, variable wind. I had to work several short lasting bubbles for the first 20 minutes, usually catching a new bubble at the treetop level. Then the next thermal was strong enough to get the plane to 200 m, and then the rest of the flight was easy. I could have been much longer but my neck was getting stiff and my wife called me for lunch .

Honestly, I am not sure I like these long flights. It is a fun to hunt for, and ride up on thermals, but once the plane is high enough it could become boring. Maybe, I have some screws loose .

Happy thermaling to you, guys,

I actually managed a couple of 20-30 minute flights today; it seemed like the whole valley I was flying in was cycling at the same time. There was strong lift everywhere for ~20 minutes, and then sink everywhere with no lift to be found. I'd find a big climb right off launch, spend the next 20 minutes trying to keep the glider at a reasonable altitude while racing around the valley as fast as I could in the widespread lift, and then spend the last 10 minutes scratching at whatever non-sink I could find. I gave up after three hours because my eyes hurt from trying to keep the glider in sight!

Welcome Punker, I don't think I've seen you 'round before.
Sounds like a good day soaring, wish I could do half as well.
