X5J April 3rd and 4th Sign Up


Welcome back for a seventh year to X5J eXtreme.

Contest Schedule for 2010


April 3rd/4th
May 22nd/24th
June 19th/20th
July 10th/11th
Aug 28th/29th
Sept 11th/12th
Oct 23rd/24th



To enter, please post to this thread your ship and power train information, before the days of the contest. During the day of the contest post your scores.
You may fly any or all of the classes below. In general, all classes use flight time - motor time and up to 30 points for landing.

The goal has been to minimize the rules to stress a Unlimited nature for these events, so everyone with an electric sailplane will have an airframe and motor that will meet the rule requirements.

New rules for X5J eXtreme 2010
TASK: Fly three 10minutes rounds using only thermal updrafts with an electric motor powered sailplane.

X5J eXtreme UNLIMITED rules:
1. Any airframe, motor, battery, ESC, and prop maybe used.
2. Flight time has motor run time subtracted from it.
3. 30point landing tape, in 1 meter increments worth 3pts/m

X5J eXtreme SOR rules:

1. Any airframe, battery, ESC, prop, motor with 28mm diameter and 17mm
magnet bell length or less.
2. Flight time has motor run time subtracted from it.
3. 30 point landing tape, in 1 meter increments worth 3 pts/m.

X5J eXtreme AMERICA

1. Any motor, prop, ESC, 2.0kg or greater airframe, four A123batteries,
2. Flight time has motor run time subtracted from it.
3. 30point landing tape, in 1 meter increments worth 3pts/m

General Rules:

1. Any part of the airframe maybe used to determine max. landing points.
2. Round motor and flight times to closest second.
3. Motor must be running at launch.
4. Each second of flight time is one point, seconds greater than 10minutes are subtracted.
5. First and additional motor runs, one point per second, loss of landing points on second motor run.


Hope you can joins us for the fun.

The Best Soaring

Hello Robert, thank you for your continued hosting of this event.
I'm in again as long as the planets align that weekend. I will be flying my HiAspect 3.1 with a Hacker B40/9L+4.4:1+15x10+Neu3600XP. Let's hope the timing works out.
Good flights to all,
-Eric

Do you think you could change the prop, and turn those 10 second runs into 5 second runs?
What esc are you using?

What prop do you recommend? I'd love to turn them into 5 sec runs . I'm using a CC60, but could change it to higher. Any recommendations?
Thanks,

Sure, the old tried and true 16x17 RFM prop and CC125.

For you, it will give you right around 1000 watts.

Check out WWW.flydma.com.
Look at their P-CALC.

I am assuming a 3s lipo.

I hope to be able to fly in the April event (Unlimited Class); I should at least be able to fly on that Saturday.

As usual, I'll fly an Art Hobby e-sailplane in the range from 1.9 - 2.5 M. If not too windy, I'll most likely fly my 2M Andromeda. All options have a direct-drive, brushless inrunner power system, and a 3S 2250 lipo pack.

Pike Superior, with the wind forcast, 15 to 20mph, it will be needed.

B50 LMR, 18 x 10, 4-A123 which do like the warm weather coming this weekend.

Hope everyone has great weather for the weekend.

The Best Soaring,
