X5J eXtreme March 21,22 Sign-Up

Welcome, back for the sixth year.

Introducing new classes: that will run with the X5J eXtreme rules except without a handicap on motor type.

X5J 1.5M class Wingspan 1.5M limit, motor small outrunner (bells depth limited to 17mm), maximum weight 452.8g or 16oz. Maximum lipo nominal voltage 7.4.
5min flight task. Flight time - motor time. 30 point landing tape.

X5J America class
Power 4s A123 cells, minimum weight 2.0Kg or 70.7 oz. No motor handicap.

I will score these classes seperate from the X5J eXtreme, and place X5J America class, in the final standing.


Remember all photos of new ships and OLE favorites are encouraged.

Please read all rules, if you have not flown this event before, everyone else, will note they are unchaned from 2007.

X5J eXtreme Rules:

1. Any electric powered sailplane can enter this contest.

2. There will be three 10minute flights. One point per second of flight time is scored and, one point deducted for each second over the 10minute-flight time. Maximum points possible 600. Round to the closest second for your flight time.

Example 9minutes 50seconds = 540pts + 50pts = 590pts
10minutes 4seconds = 600pts 4pts = 596pts

3. Motor run time is unlimited but subtracted from the flight time.

Example, 600 flight pts - 19 motor run pts = 581 total round pts.

4. Landing points to be measured from the center of the landing circle, to the closest part of the plane. For each meter from the point subtract 3 points from 30pts . See attached file for table.

5. Motor handicap: brushless 95%, brushed Cobalt and brushed car motors 75%, Ferrite 45%, and outrunners with a 28mm or less bell diameter and 17mm length 68%, Speed400 30%. The X5J America Class will have no motor handicap. Actual motor run rounded to the closest second. Then multiplied by the motor percentage. Round this calculated value to the closest 1/10th of a second.

Example Cobalt motor time 34 .6seconds = 35seconds X 0.75 = 26.25seconds = 26.3 seconds

6. You may restart your, motor as many times, as needed, but on the second motor start, you may not add landing points. A second way of stating this rule. If you start your motor after launch run of the motor, you will not receive any landing points.

7. Your flight is limited, a single dawn to dusk flight day of your choosing, during a 48 hour period.

8. Any type of battery cell is legal.

9. Temperature Factor to be added to total flight score. See the attachment for the temperature table.

Timers still need two stopwatches, this was easier then I thought it would be. Work out a signal with the pilot, if he is going to restart the motor. (I.e. "")

This is the simplest way of scoring I have been able to come up with.

Flight time - closest second
Motor run - closest second
Calculated motor run - closest 1/10th of a second
Landing points - see table Rule #3

To compete: Please list your plane, gearbox, prop, cells and type, weight, and any other interesting facts, pictures are always welcome, to this thread.If someone else, not on the Web would like to fly with you please list him or her, on or by March 20th.
To all who enter,

The Best Soaring

Count me in too. I'll be flying the Omega 1.8 with a Scorpion 2215/12x8/3STP2100 or the HiAspect with a B40/9L/4.4:1/15x10/3sTP3300 (if I get it fixed in time).
Good flying to all

I'm in.

Unbelievably, I was unable to fly electrics for all of February.....there was simply too much icy snow on the ground.
I not only missed this Postal, but the Australian Postal (AEFA) as well.

I flew my DLG exclusively, as I am able to hand catch it, or land it on the Airport driveway.

Good news!....The snow won't last forever!

I am really looking forward to this months' electric soaring.

I'll be in with my E-Topaz.

I have been flying a lot of DLG too. In fact, I worry I will miss this thread since I have not been as active in this forum recently. I had a bad feeling today as I was flying my e-Paragon for the first time in 2009 that perhaps the postal was this weekend.

Seeing I did not miss the March Postal I'm in with either my electric Allegro Lite, assuming I did not kill the battery last time like I sort of worry I did or my Paragon or perhaps even my CDROM plane.

I'm in again for the March X5J event. Depending on the weather, I'll fly either a 1.9 or a 2.5 M Art Hobby e-sailplane with a direct-drive, brushless inrunner power system, and a 3S 2200 lipo pack.

It has been very windy in my part of the world over the past many days. I hope that changes by the X5J weekend!

I'll give it a go again in the 1.5M event. Chrysalis HLG-e, Scorpion 2208-30, 2S lipo, 13oz AUW.

It will be a glider day for me. Our club is having their monthly LMR event that day too.

To bad it was not last weekend. You could have thermaled a pattern ship on either day.

I'm still building my new airplanes, so I'll fly my speed 400 model again. 4:1 GB, 11x8 prop, 8x600AR.
