X5J eXtreme August 22th & 23th 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.

>>>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 August 21st. HOPE YOU CAN ALL MAKE IT OUT FOR THE eXtreme<<<

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 unchanged 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 all who enter,

The Best Soaring

Im in again for the August X5J event. As usual, depending on weather conditions, 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.

I'm going to be down on the Oregon Coast on a big Slope trip that weekend, so hopefuly the last thing I'll be doing is flying electrics. If the wind is scarce I'll try to get some timed flights in..

I'm hoping to fly for regular X5J with the 2 meter Sprite running Neu 1110 w/gearbox, 44 jeti spin, 3s 1350mah I can't rember the prop size off hand, or the E Blaster2 with AXI 2212/12 , 22 amp Jeti spin, 3s 910mah TP pack , the prop I can't remember I think it's a 12x7 Rasa or something like that.

I might also fly the EB2 with the same system, but with a 2s pack for 1.5m class.
