The april big sky international electric sailplane contest

THE APRIL BIG SKY INTERNATIONAL
LONGEST DURATION CONTEST FOR ALL ELECTRIC LAUNCHED GLIDERS
THERMAL SOARING AND SLOPE SOARING
RULES AND INFO:
Contest will run from 12:01 am April 1 to 11:59 PM April 30 Eastern US time.
The contest is for ALL electric 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 this to all e-gliders and, if you like, e-airplanes too. If it glides, it qualifies.
In Thermal Duration, the contest is split into two classifications, 2-meter and under, and Open class.
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. I expect to see themal times in excess of 30 minutes and slope times in excess of an hour. But you are welcome to post any flight time you wish. Get your name on the list and be famous!
THE PLANES:
* Any electric motor system
* Any wing controls and any wing span
* Any construction
BIG SKY - 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 - 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.
Report Format:
Your Name - Real or RCGroup Name - your choice
Glider/plane name and wingspan:
Thermal or Slope:
Date and Time of flight:
Duration of flight:
Location: Nearest City and State or Country
Comments - You are welcome to report anything you like about the day, the flight. Pictures, videos, gps plots, etc are welcome but not required.
I will maintain the thread and keep the second post updated with the top 10 Thermal (2 meter class) top 10 Thermal (Open class)and top ten Slope reports. Only one flight of each type will be recorded in the standings for each pilot. A new better time will replace the original.

Date: April 1, 12:01AM
Duration: 11:50:52 (30 second power run)
Location: Raleigh NC

I LED-ified my Radian and launched into a thunderstorm at 12:01AM. The swirling winds were a real challenge and I nearly lost the plane to a lightning strike. One tip is slightly melty looking now and it doesn't quite fly straight. I'll have to do something about that. The plane got blown so high all I could see what a glowing speck against the clouds, but it stayed up there! Truly amazing lift for so early in the day. Eventually, the coming sunlight gave me some additional thermal help, and it was an easy cruise until I just had to come in and land due to biological issues.

A truly AMAZING flight!

Cool....modified by.......God/nature!
Flight interrupted by call of nature.

I'll bet the lightning did not hit the plane, but you flew through some supeheated air/steam. I think thunder is generated by rapidly expanding superheated water vapor (if I remember my HS science correctly).

So, on April 1 (april fools day), 1 min. after midnight, you launched your radian (foam plane) into a thunderstorm and got struck by lightning. Not to mention, you flew for 11 hours, 50 min. and 52 seconds which resulted in a biological issue (in your pants?).

Nice flight!

Not such a good time, but it was the first of the year. Last year I flew 18 mins which is a lot better.. Maybe try again tomorrow if the weather permits...

High overcast, not much sunshine, calm. Found one flyable thermal in ten launches. Of course there was the guy with his 4M plane...may still be up for all I know.

We're getting better But still not as good as I want to.
The problem is that most of the time I know there is some lift. And mostly I know approximately where. but I always manage to loose more altitude in the sink of the thermal than gaining in the lift. So I have a question: If the plane rises, but looses speed and continues to fly slowly does that mean lift or does that mean I just flew of the edge of it?

Interesting question, I too would like to know what people think of this, I find that if that happens I circle around and watch for any lift, if there is none I widen the circle and if there is still none then I go look elswhere, if I do hit a bit of lift I then tighten the circle and adjust to stay in best lift.
I usually find lift best on calm days by watching plane carefully and if it hits turbulence then I start circling by turning into turbulence and do as above.
On windy days I find it much harder and really just rely on watching if plane is going up or down.
Sometimes I gain height by flying between an area that makes plane fly slow and and one that makes it fly fast, and staying in either does nothing but circling thought both seems to gain height????!!!! This is usually on windy days.

I'm sure there are better ways for thermal hunting and I would like to here what other people do, and what they think of my methods, constructive criticism is always welcome.

It may be that different planes react differently, but generally speaking, my Radian Pro will slow down when it hits lift. It will speed up when it is leaving the zone of lift. Maybe the because the tail is in stronger updraft when leaving the lift zone, and vice versa when entering the lift zone.
The most obvious sign is when one wing dips, indicating that the opposite wing has encountered an updraft. That's when you turn into the high wing.

Other than that, it's just a matter of flying the plane a lot and learning how it reacts when it hits obvious lift. Trial and error.

I still have trouble staying in lift sometimes simply because I don't recognize exactly how far and how high the plane really is. As it gets closer in, it seems lower, and as it gets further out it seems higher, just because the plane appears smaller. Sometimes it appears that the plane is getting higher when it's really just getting further away. Depth perception.
