22.214.171.124 Course Layout and Organization
a) …The sighting device for the safety plane is placed at a distance of a
minimum of 20 m from Base A or B outside of the course (if possible).
d) After the aircraft is hand launched and the stopwatch is started, no
further launching is allowed and flight is being considered as official, the
model aircraft being airborne or not.
126.96.36.199 Distance Task
e)…must remain at Base A on the safe side of the safety plane until the
g) The flight is annulled if the duration and landing task has not been
started and also the landing does not occur on the designated flying side
of the safety plane and within 100 m from the intersection of that line with
Base A or B.
h) If the model aircraft shows technical problems (i.e. motor stop, radio
problems etc.) and/or flies in a unsafe manner during the distance task,
scoring will stop competitor must land the model immediately. The flight is
given a score of zero (0) for the round. Unsafe flying includes crossing of

SEFSD Field Specific Rules
Organization of Starts. Flight order for the first round will be by random draw Friday Evening. The first flight will be at 11:00 AM Saturday morning. We plan to complete 4 rounds on Saturday, and 4 rounds on Sunday. There will be one throw out score. Due to use of lithium batteries and allowance of 1 battery pack per 2 rounds per competitor, the contestants are expected to be able to fly consecutively without delays for battery charging.
Course Layout and Organization. SEFSD Club field cannot accommodate simultaneous and uninterruptible Distance and Duration flight tasks. Therefore, we will strive to have at most (2) models on Duration or (1) model on Distance and (1) model on Duration with 4:00 to 7:00 minute spacing. There will be (2) sets of landing circles provided : one at the West end of the field and one adjoining the Distance Course. The first pilot in the air shall use the West set and the 2nd pilot either the West or Distance set. There should be no landings occurring during a Distance task if the Duration contestant seeks maximum points. In the event of an emergency on Duration, the Administrators shall reserve the right to abort the Distance flight to allow the Duration Contestant to safely land.
Altitude Restriction. SEFSD Club field has a 400ft altitude restriction enforceable during proximity of full scale aircraft . Interference during Distance will be judged by the Base A official, the pilot directed to land immediately and be granted a reflight. Interference during Duration will be judged by the timing official; the pilot may be directed to change course and/or lower altitude and may be granted a reflight if interference is judged detrimental to flight and not collateral to circumstances within the control of the pilot such as running out of battery energy. The pilot is expected to honestly communicate his circumstances with the official timer.
Distance Safety Plane. SEFSD Club has an East-West fence adjoining the pit area. The Base A and Base B sighting devices will be aligned with that fence. Pilots are expected to fly from the South side of the fence, behind the sighting devices. The safe flying area is nominally 5 m North of the fence and not South of the fence in any case.
Entry fees for the Team Selection Trials will be $75 USD. Entry fees will include lunch, and drinks at the field each day. Lunch will be available to non-contestants for $15. San Diego weather in late September ranges from 65 to 85 degrees f. The event will be held at our field at the South Shores Park in Mission Bay, San Diego, CA.
Best of luck to all entrants and please feel free to pass this information on to anyone interested in joining the competition.
