Scale gps triangle race

We will be hosting a scale aerotow XC race using the GPS Triangle method popular in Europe.

This will NOT be a scale aerotow (funfly). Those attending must be competing. There are plenty on aerotows to go to and not many competitions.

It will be a Friday practice Saturday and Sunday race in the later half of July 2011.

Perhaps three classes- Vintage, 1/4 scale, 1/3 scale depending on the entrants.

Max entrants 20.

Start asking questions so we can find the answers together as this is something new to me.

Regards Dean

Dean, I'll be happy to consult with the folks running this in Europe: http://www.gps-eurocup.ch. For now, I'll see if they have 2011 dates set already. Maybe, if you slotted your date in between two of theirs, one or the other European pilot may be interested in attending.

Dieter,
This all got started when John Ellias and I observed Rick Shelby fly his 1/3 Ventus at Visalia. I knew I had to try it.
Because you fly in a defined area I felt that this could be done at Montague.
I asked Rick to come up with time period when it would least conflict with other events. His choice was later July early August. Last year there was no flying because of fires so I'm thinking of July.
That's not alot of flexibilty and the event calander is filling up fast so a firm date needs to be decided soon.

Regards Dean

Dean,
Please try to avoid the Nats dates (July 10-17). Would improve my chances of coming up with the K8.

Jim,
I added the vintage class as I remembered how well you and your Ka 8 did years ago.

Let's make it July 29 practice. July 30-31 contest. Any objections?

Regards Dean

Obviously, open summer dates are hard to come by. I'll see what I can deliver on short notice.

Excellent Dean! I look forward to it. Any thoughts about having an "Unlimited" class where you just bring what ya got (TD, XC, F3B/F/J, etc)? Might broaden the reach a bit.

Dean - TP definition via GPS downlink to PDA or visual?
1/3 scale would not stand up to my 4.2M ASW
Please provide more details - and what assistance you might require so I can review and plan accordingly.

You're the greatest

This time around will be scale only. Less is more as I don't know what I'm doing and winging it with other folks help. That being said I would love to see how a MXC would stack up. I guess we need one XC ship!

Downlink via GPS. Will have loaner units available, hopefully two units.

I'm doing this because I feel it is the only aerotow venue that can be done safely at Montague and I think the event has a great future.

If you have a smaller scale glider you must move up to the next higher scale.
3.5 flys against 1/3. 1/5 flys against 1/4. Lots to work out.

Regards Dean

Roger that. I'm sure it will be as great or better than every other event you put together.

Dean,

Crystal clear now - Let me know what you need help with!
Do you have the scoring spreadsheet S/W yet?
When will you plot the course coordinates - do you need help with that?
No-Fly-Zone - Nice if the RTD could send a warning to the pilot if the vertical plane is broken.
Each group by aircraft size (range) is an excellent start
But still kept at the fun level
Spicer has his MXC setup for AeroTow we can make him the Guinnea pig
Mr. Weaver was working on a cost effective alturnative to the euro unit, but is on the back burner. I think this event will escalate interest and sales.
Ralph if you are read this hint hint
Iphone App downlink, Android code already exists hummmm more toys - heh heh

Dean - One other thing - planning for the installation of the unit?
Do you have any data on the size and weight?
This would help me in the organization of the cockpit area and antenna routing etc....

TIA

I've got a GPS sending data to a laptop and displaying the flight path. I haven't done more yet because I'm not sure using a laptop is the way to go. Battery life, size, cost, poor readability in sunlight are all issues.

I don't really like the PDA either. It's expensive, hard to see in sunlight, not really useful for anything else.

The iPad might work, but it doesn't have USB input for the GPS data, is a bit expensive and is not readable in direct sunlight. I'd rather do an Android pad when they come out. Android is easier to develop and the USB is more versatile.

I'm really excited about the new Kindle Development Kit. You can now develop custom software for the Kindle. I don't know if the USB port will read GPS data, but it's cheap at $139 and very readable in direct sunlight and the battery life is great.

Some other issues to solve, how to get the scores sent back to a main scoring computer? Hand typed, USB drive,...?

Maybe I'll start looking into this a bit more if the interest is there.

Ralph,
I think the interest will be there. In fact both Montague cross country contests next year will most likely will be International events.

This is great news for scale soaring! Hope the technicals and logistics get worked out so they will be easily implemented for the rest of the US. Thanks, Dean, for bird-dogging this first event.
Also, thanks to the "techies" for developing the existing GPS race technology for the US market! Looking forward to the reports.
Asher
