GPS-EuroCup / GPS triangle racing


There appears to be some excitement generated by folks giving this a try at the 2010 JR Aero Tow so it seemed reasonable to restart this thread. Here is the official website:

http://www.gps-eurocup.ch/

And where you can find out more about the gadgets that enable it:

http://www.icare-rc.com/skynavigator.htm

If you like scale sailplanes and you like the idea of racing, this is it. If you like scale sailplanes but don't like competition, you can use this system to improve your flying skills and enjoy your scale ship even more.

A couple of questions to kick off the discussion:

1) Is there any interest in having these kinds of events in the rest of the world, outside of Europe?

2) What is your or your club's monetary pain threshold for participating? In other words, how much would you be willing to spend to play?

3) Would you be interested in posting your flights to a website that other participants could see?

4) Do you like the idea of flying with a spotter/tactician and having him guide you around the course or would you rather participate solo?

5) Should all planes of all sizes fly together or should they be grouped or handicapped by performance and/or size?

Let's get this going!

Mike

Hands-on experience and thoughts from the 2010 JR Aero Tow


Reposted from the "JR Aerotow 2010 Pictures" thread to keep it in a findable place:

Once I get home from this trip I will have more to say about it. All the info should be available or linked on the Icare website. We just need some cheaper hardware to make it more affordable.

On Saturday, Etienne asked if I would fly the coarse so they could get some more video and pictures of guys trying it. I'm glad he did, it turned out to be a blast. The GPS unit is a thin little device about an inch and a half square. It has one lead which plugs into any receiver port or Y connector just to get power. It weighs nothing. Your plane is towed to an altitude of at least 500 Meters, ( 1625 feet ) and you release. I say at least 500 meters because you can not cross the imaginary start line above that height. The best thing to do is go forward of the start line and release at 550 meter and then turn and zoom back picking up speed, turn and cross the start line with a full head of steam. At his point, you fly up the coarse ( 500 meters also ) to turn point, which again is imaginary, so Etienne is standing next to you with a small handheld PDA with the software on it that shows him the coarse, altitude, speed, heading, etc. HE tells you to go right or left based on the track of your plane, wind and coarse layout. Once you make the turn point, you must turn for the next leg. Its a triangle coarse, so once that leg is made, its a downwind run to the last point. Gather as much speed as you can without burning all your altitude, because when you reach the turn point and head to the start/ finish line, you need to do it again. Thats right, two laps around the coarse. This time around you are not so worried about saving altitude. Again, play the wind and ground speed. All this time, Etienne is coaching you on which way to turn and when the turn-points are coming. The last leg to the finish line is a sprint, nose down and full speed ahead, just make sure you will get there. Most importantly, after crossing the line, pull up, dump water and a victory roll!!! oops. sorry, that's the real guys.
Everyone should at least try it once. I hear a rumor that Eagle tree is working on something. Maybe a more affordable system.

Mike,
I think GPS racing is a natural development for scale sailplanes. Whenever kindred minds congregate, competition develops and this looks like the best case scenario to accomodate that at this point. Those that are "game" competitive will embrace it, those that are "wallet" competitive will be able to participate safely, and those who are "aesthetically" competitive may be enticed to uncover a new avenue of satisfaction.
One of the things that is satisfying about scale sailplanes and aerotowing for me is the relaxed atmosphere and commraderie. I enjoy seeing old friends and being in an atmosphere where pressure is limited and you are surrounded by beautiful planes. That is relaxing for me and I always enjoy those aspects. At the base level it appears racing might be nested into most any event without sacrificing those qualities but obviously some events could be organized completely around racing.
There was a push in the late 90's and early 00's to develop sailplane aerobatics in the US. It died on the vine. Not sure why but one could speculate that the level of piloting skill and special planes required, the emphasis placed on competition at events that were small in attendance and few and far between took their toll. Lets face it, once you get over the initial hump of flying a large scale sailplane and aerotowing it doesn't take a lot of practice or skill development to do what is required for a fulfilling day of flying and for those that enjoy the beauty of scale sailplanes, that is a draw. Maintain your equipment and you can fly just 2-3 times a year and do what needs to be done. You don't have to practice every weekend. Every flight you can walk away from is a success.
Having said this, I think GPS racing is something that might fit the bill for ageing, fairweather pilots like me. You don't have to practice maneuvers or spot landings every weekend or have the latest wiz-bang airplane devoted to the task. You can be as competitve as your ability to read air, invest in the required equipment, and time devoted to practice will allow. But you still can run the course without looking too incompetent or risking your pride and joy.
It looks like there is growing interest in this event and time will tell if it finds a home in our field of common interest. I for one will be watching and waiting for the price of entry to drop to my level of competency.

Asher,

In my opinion, you hit the nail on the head. This style of "racing" seems like a nice, low-key way for a bunch of guys to get together and show off their scale planes. As you said, you don't need to go out and devote hours and hours of practice time to shooting spot landings or shaving a second off of a speed run. I think that will be attractive for folks that have done/tried the TD/F3X/whatever competitions and now want a more relaxed (low-stress), fun and asthetically engaging activity.

I really like the fact that there is minimal setup. You don't need 8-10 guys to put together an event and you get to do plenty of flying in the 30 minutes rounds.

Also from what I've read and seen in photos of the European GPS Cup events, it looks like laid back good excuse for folks to get together and show off their planes. Their "rule book" makes me think it's intended to promote comraderie and not intense competition.

Finally, I think making it cheaper is going to be important,

Mike

Bringing this back to life


I've been reading some of the contest reports from this year's GPS Euro Cup and thought others might enjoy them as well:

http://www.gps-eurocup.ch/Wettbewerbe/Wettbewerbe.htm

I know that several folks, including myself, are working on making this style of flying affordable for the average scale guy (whatever that is) and am hoping that we can get some momentum here in the US, Australia, Canada, South Africa and other countries.

I just reread the Euro Cup rules and they have opened it up participants outside of Europe so I think it's time to step up and show the originators of our sport how it's done!

I've attached a sample report from earlier this year. It's fun reading and sounds like a blast. Here are some photos to go along with the contest report:

http://www.gps-eurocup.ch/Bilder/Ima...010/index.html

The 1:3 304 Shark and Antares appear to be the ship to have for the "big hitters" but apparently some scratch built ships are also doing well.

Eagle tree GPS


Hey Mike,

Do you think the Eagle Tree GPS would work in this case? I am thinking of buying one.

Currently there is no way to get the GPS data from the Eagle Tree ground receiver into the PDA. I have asked them to add a bluetooth module for that purpose but it is not a top priority for them. Perhaps once we get this up and running that priority will change.

I have finally put together a hardware system that works with the existing software. It is still a bit clunky so I need to refine it and also try a couple of other ideas. At least I have something that I can use for demonstration purposes now. The hardware I have now costs about $500 compared to the $1500 needed for the original system. It may eventually get a little cheaper, but not much. I still need to do flight testing with the whole system to make sure everything works together, but from the testing I have done so far I am confident it will work. Hopefully I will have some good news to share in a month or two.

Rick,

Will you be bringing it to Visalia in a few weeks so we can see it in action? I would also like to see how the course is set up.

Oh, you betcha. I will be practicing with this unit whenever I fly the Ventus from now on. Once I know it works, I will build up another unit to loan out to anyone to try.

I like this type of racing. To me, crashing a glider into the ground, nose first, and calling it skill, is an oxymoron. One can take the hints of what is to be accomplished, as well as those things that need to be safety items, from the full size glider rules. Good loggers and telemetry will make it work.

Excellent, Rick! Does the $500 include the PDA?
