Small Field Contest Rules

Small Field Rules are observed for most contests held at the Waegell field and at the OCD events run at the Lakeville field.

A. Contests will begin at 8:00 AM and end at 1:30 PM.

B. Entry fee is $0.25 per event, unlimited re-entries are allowed. High time in each event takes the Kitty.

C. Two formats for wind conditions:
1. Light or no wind: Three ninety-second maxes. If tied due to maxout, then the tiebreaker is a one-minute precision flight. The flier closest to one minute wins the event. (For record-keeping purposes, flyoff time up to 60 seconds is added to the flyer’s total. If the flyoff time exceeds 60 seconds, the time exceeding 60 seconds is subtracted from 60 seconds and the difference is added to the flyer’s total. Flyoff time exceeding 120 seconds counts as 0 (zero).)
2. Significant drift: Scratch contest or three one-minute maxes, and the tiebreaker is as in C1.

D. Points will be awarded for each event:
1. First place is 5 points, second place is 4 points, third place is 3 points, fourth place is 2 points, and all other places are 1 point. DNF is listed, but no points are given.
2. At the end of the year, the flier with the highest point total wins the Small Field Champion title and receives the Walt Getsla trophy. Juniors win the Junior Small Field trophy. A Junior is defined as someone 18 years old, or less, on July 1.

E. Mini-Moffett: Rules are the same as the regular AMA Moffett except that the total wing and stabilizer area can be no greater than 150 sq. in. (as viewed from above) with negative or positive dihedral in either. This model class is approximately 75% of the area of a regular Moffett.

F. Open Rubber: Any design rubber-powered model with a wingspan thirty inches or less (projected), or 150 sq in or less is eligible.

G. OCD Catapult Glider: This is a non-AMA class originating at the California State Fair in 1937 and traditionally flown by the OCD since then. Rules allow a glider of any dimension and weight with a securely mounted launching hook to take the stress of up to 20 pounds of linear thrust generated by eight thirty-inch strands of ¼” rubber. A round is composed of up to six consecutive flights. Unlimited re-entries are allowed, and each re-entry starts a new round of six flights. In the event of three consecutive max flights, the flier may fly one more time-target flight. Winner is the flier with the highest total of three consecutive flights (plus flyoff flight) from any single round. The OCD member with the highest place point total from the Mowry contests wins the OCD Catapult Glider Championship Trophy for the current year.

H. ½ Coupe: The airframe weight can be no less than 35 grams and the motor weight cannot exceed 5 grams.

I. OCD Scale: A rubber powered model with an enclosed motor that is fashioned after a “real” airplane. No scale points are awarded. Flying is per C above.

J. 1/4A: Ten second max engine run, 0.020 or less engine size.

K. Fuse DTs are not permitted.

L. All events except OCD Catapult will have a 10-sec minimum time for an attempt.

M. Fly one-time one, so bring a stopwatch.
