The photo of the actual aircraft must be posted with the required entry photos to get the additional points.

b. The Flying points are awarded on the basis of the best three flights made by the model before the Challenge deadline.

The time of each flight is entered in the database and the points per flight are awarded as a straight total of the three flights in seconds. An official flight is a minimum of 10 seconds. Entry is on the honor system.

Flying points are awarded as follows:

1 to 40 seconds.......each second = one point.
41 to 93 seconds.......each second = one half point.
Over 93 seconds...no additional points...bragging rights.

Maximum possible overall flying points = 198 (3 flight total).

Actual maximum flight times will be used to rank flying times in event of a tie.

c. The Overall Combined Score ranking is the combination of the Appearance and Craftsmanship points and the Flying points. The maximum possible Overall Combined Score is 300 possible points. Actual maximum flight times will be used to rank Overall Combined Scores in event of a tie.

d. The staff at Guillow has kindly volunteered to do the appearance judging from the posted photographs. Their scores are final.

e. When all the appearance point scores have been received by the moderator the results will be posted in a database, 2013 Challenge Results.

11. Posting:

a. An album, 2013 Challenge Entry Photos, will be set up for the required entry photos. Post a 3/4front view and 3/4 rear view jpeg image of the model, with your name + 1 for the front view and + 2 for the rear view. The image should have at least 720 X480 resolution with 1024 X 768 desirable. A database, 2013 CHALLENGE ENTRY, will be set up for the flight times and short comments about the model.


Let the Fun begin!
