NEW YEARS DAY, X5J eXtreme 2007 Sign-up

X5J eXtreme 2007 and Event dates.

Welcome, back for the fourth year.

Please read all rules, new is the order of the rules from 2006, added is the small out runner class of motors, and movement of brushed car motors to the cobalt class of motors..

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%. 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, by New Years day 2007.

To all who enter,

The Best

Thanks again for organizing this Robert!

Hi Ken,

l don't think the 28 in the axi number is bell diameter. Using Hobby Lobby numbers I came up with a bell diameter of 27.7mm for the AXI 22XX outrunners.

My 2208 has a dia. of about 27.7 mm, I realy don't for the life of me know what those numbers mean, I was wondering if mine squeezed in under the depth limit?

Take care, Ploof

Hi Ploof,

I have no problem with the AXI 22XX series since first, alot of people have these motors and the diameter is 28mm or less, and second the end of the bell has a taper that would be hard to average to measure bell height.

Hi folks,
I'll give it a try once more.
Nano Floh fuse with a Cikada free flight wing. Speed 400 with a 6x3 folder on 3 lipos (1250).
120cm span and 400 grammes.
Maybe I change the wing for a GP fling wing, I have to make some test flights first.

I am in, if the weather cooperates. It is getting cold here now. I had to put on a long sleeved shirt today.

Da plane is:
Supra w/ Les Horvath pod and 1" constant boom. Hyperion 3025 with 12X8 aeronaut folder. Jeti 80 amp opto and motor powered by 4 cell A123 batteries running abt. 55 amps static. Receiver is JR 700 powered by 2cell 800 mah polyquest lipo for 6 X HS81mg servos (no voltage regulator!). Do those micro servos suck the amps or what? Radio is JR 8103. AUW abt. 62-64 ozs. Mistakes in the build added abt 4ozs. Spar is exactly half the carbon laminate Drela recommends. Tail group is built to Supra specs except using 1.7oz Kevlar instead of 1.0 oz Kevlar. Added 1.2" wide strip of .003 carbon laminate to trailing edge for ruggidness during the build. EDA is per Supra instructions @ 6 degrees, 2.5 degress in center.

That is all. See you on the cyber-flight line.

I'm in again too.

Allegro Lite. Speed 400 4:1 gearbox, 12x8 folder. 2S 1320 lipo.


P.S., Bob in Seatown. This is a postal and if you search on "x5J" you will see past months results, photos, scores, etc. It is quite a bit of fun, it is free, and you should join in! Any electric plane works.
