Contest

One-on-One F5J is On!


Greetings fellow F5J'ers. With the current virus concerns it is a good bet that we are looking at a month or even longer where F5J USA Tour contests continue to have the potential to be cancelled in favor of rescheduling later in the year. While flying in bigger groups is out for awhile that does not mean we still can't have fun flying competitive F5J, it just means we have to use a different format until things get back to normal.

Description:

This post is the launch of a new F5J "postal" contest series that can be flown by any pilot in the US or anywhere in the world. You will self time and self record your flight scores, then you can post your scores in this thread. Everyone is on the honor system. Every Monday I'll post the top session scores for last week's flight sessions. Here's how it works:
  • For each contest session you need to fly a minimum of three (3) 10-minute rounds. Fly as many more as you want.
  • Submit your round-by-round scores in a post in this thread. If you don't have an F5J landing tape you can estimate 1 meter for every 5 points. In your post feel free to describe weather conditions, your planes, interesting things about your flights, and even include pics if ya want.
  • Your contest session score will be calculated by summing your raw (not normalized) scores from your best 3 rounds. See example below.
  • Fly as many F5J contest sessions as you like in a given week. I will use your best session for your weekly score total.

Every Monday when I post the top winners for last week's flight sessions I will also recognize the lowest productive launch heights i.e. launches that produce flight durations within 10 seconds of the target 10-minute time.

Sound fun? Great. Go get 'em.

------------------------------------
Scoring post example

Here's an example of a contest session post showing how contest flights are scored:

"I flew 4 rounds today. Fairly windy. Was by myself at the field flying my 51oz WhizBang 4mtr F5J.
Rnd 1: 8:56 time, 45 landing, 143m height
Rnd 2: 7:32, 0, 121m
Rnd 3: 9:57, 45, 212m
Rnd 4: 9:49, 50, 223m"
---
Scores are calculated as 1 point per second + landing - start height penalty. So the above flights would result in the following raw scores:
Rnd 1: 8:56, 45 land, 143m Raw score= 510
Rnd 2: 7:32, 0, 121m Raw score= 392
Rnd 3: 9:57, 45, 212m Raw score= 506
Rnd 4: 9:49, 50, 223m Raw score= 470
The absolute best raw score is 650 with a launch height of 0 meters. If anyone submits a flight with a 0 meter launch I have a special award reserved for them .
-------------------------------------

A small request: if you have virus things to discuss we hope you can find another thread for that.

Thanks much and let the flights begin!

Practice Audio File


Here are two 10min practice audio files both in .mp3 format courtesy of Tailwind Gliders.

There is a 1min prep time in the 10min Task file and a 5 second prep in the 10 Minute Task F5J file.
The 10min Task file counts up after the task time so that you may also use this for your other soaring competition tasks.

Hi Matt, great to hear you are in. FYI when I said the max flight score is 650 I was wrong by 1 point. It's 649 since the best time in F5J in 9:59. However, if you fly your tasks in the snow that is worth 1 bonus point for a max 650 points We may come up with a few other conditions that will get you a 1 point bonus. I'm open to suggestions...

I'll try to get in on this. If I can go to contests I'll at least try to phone it in.

Great idea. When I fly I treat every flight like a competition round so all I'll need to do is write the numbers down and report them.

In Australia we have been doing almost exactly this for over 5 years. Once a month we email our score for one flight to a co-ordinator and scores are kept from Feb to Nov, skipping our summer/holiday period. Some very good scores have been logged. You can choose your day and air, you can even find a thermal, land and relaunch into it for a very low launch and a very high scoring flight. Its all good practice.
Unfortunately this years postal comp is in suspension because all our club fields are closed for flying under our governments isolation rules.

Every flight is a round, or you can choose the best 3?

.....I see the answer in the rules now

Scores post from BillC and ChrisB


Had a full day of flying with Bill Curry at our favorite field. By early afternoon it was 72 degrees with 10-12 breezes (sometimes with short gusts to ~15), partial clouds down to 4500 ft. Good thermals and enough wind and low turbulence to justify ballast. This site is on the edge of hills rising 200'-400' to the East.

Bill's flights:

9:55 time, 30 land, 106m height -- Ultima-2, no ballast. Landings were tricky due to the low turbulence on short final.
9:59, 40, 129m -- Added 3 oz of ballast. Better but not enough weight.
9:59, 30, 143m -- Added 6oz ballast. Bill said this really smoothed out the flying.

Chris' flights:

9:58 time, 35 land, 129m height - Xplorer 3-4m F5J. No ballast. Low turbulence caught me by surprise.
9:57, 25, 173m - Added 7oz ballast. Launched too high. A low gust caught me again on landing. Need to keep short final airspeed up!
9:58, 50, 105m - Faster approach on final, mucho better.
9:56, 45, 118m - Vertigo, no ballast. Turbulence made thermaling a bit harder. I expected a more difficult landing w/o ballast but the Vertigo cut thru the air better than the X3.
9:57, 50, 104m - Added 6oz ballast. This really smoothed out the flying and landing.
9:56, 45, 94m - Same ballast. Lowest launch height for this session. If you tried to launch much lower you stood a chance of not hooking up.

All in all we had a great contest session.

Nice flying Robert, all your launches 62m or below!

Had a chat this AM with Darwin Barrie who came up with a good idea: how about if we (optionally) include a list of specs for the plane(s) we use? Would be interesting to compare. Plus, we have a fair # of guys who are new to F5J and would benefit from seeing this info.

Nice evening flights in Indiana


I had a nice time flying this evening from 7 - 8 pm. It was the earliest I could get out to the field. It was a calm evening, 60F with light wind. There was weak lift at 100 meters on the first flight. The second flight I tried a low launch, thought I had found lift, but not very successful. Third flight, no lift was found. Forgot to take a picture of the plane, so posted the altimeter output....Overall, a very fun session.

Simitri Standard at 55 oz, 4S1050 Mah Tattu, Castle Light 50 Amp ESC, Neu 1102 P22, 11x7 Aeronaut prop

1) 165 launch 9:59 0 landing 516
2) 59 launch 3:34 35 landing 219
3) 155 launch 8:09 40 landing 456

Stay safe and healthy
