Racing

History

Since its beginning, as the “FB-XR”, designed and flight-proven by Terry Rensberger, this totally foam board aircraft has evolved into an inexpensive $40 amazingly survivable “FB-Delta” Racer. With its slide and lock together construction, the FB-Delta builds itself in just a few hours. Ten Racers, while still designated as the “FB-XR Design In Progress”, successfully completed a fun-filled 2014 Season. South Bend RC welcomes and encourages all RC Pilots with AMA Membership to join in.

3 Different Racers to Choose From

Great news for our Pylon Racing pilots! There are now 3 different foam board models to choose from. The original FB-XR (Delta), a version of the Lazer and another with mid-mounted motor. All of these setups use the exact same power system, making them pilots choice on which one they wish to use for racing. Contact Paul Lashbrooke to get your basic airframe. He cuts them out on his CNC router for a minimal fee. And, they come with a 3D printed motor mount.

Resources for Pylon electronics

Originally, our Delta Pylon planes were powered with electronics from Wingman RC. Unfortunately, it appears that Wingman RC is closing shop. To make it easier on our Pylon racers, the following list will help you get in the air quicker with less research. Of course there are other similar equivalents. Remember, when selecting a motor, it must be an 1806 2500kv and you must use an ESC no greater than 20A.

Racing Rules


Pilot Requirements:

] Open to any current AMA Member
] Paid, $5 annual “FB-Delta” Race dues, unless SBRC member
] Paid, $5 Race-Day entry fee., unless SBRC member
] New Pilots are welcome and encouraged to get involved anytime during the racing season

Radio Requirements:

] Spectrum Technology System
] 72 MHx System:
Narrow band stickered, per 1991 FCC
Each race Pilot has an assigned Frequency
Multiple Pilots not allowed same frequency.
“Racer’s Frequency List” is maintained
72 MHz frequencies, first come first served
72 MHz frequency changes per Race Director

Race Heat; Procedural Steps:

] Pilots attach appropriate color streamers to their race plane.
] The Starting Official will check for the appropriate attached streamers.
] Starting Official announces competitors for the next heat.
] Starting Official announces “Pilots you are on the clock” and Pilots have 60 seconds to ready their plane and present themselves at starting line.
] Starts, either by Hand or Launcher, are simultaneously launched toward pylon #1.
] Starting Official will call for a launch by sounding a horn when: All Pilots are at the starting line and each has indicated to the Starting Official that he/she is ready for launch – or 60 seconds have elapsed since the Starting Official had announced ‘on the clock ‘, whichever comes first.
] A Pilot may launch his/her plane after the official start provided at least one previously launched aircraft has yet to complete (10) laps.
] At the completion of (10) laps, the Pilot will land his/ her aircraft as quickly as practical, even if others are completing their (10) race laps .
] No Pilot or Counter may leave the Pilot position until all aircraft have landed.
] After the last Competitor has completed his/her race, all Pilots will expeditiously retrieve their aircraft and clear the field.
Pilots for the next heat will expeditiously take the field, with their aircraft prepared for flight.
Counters will communicate with the Official Scorer the finishing order, Judges will communicate cuts and dead lines.

] All foam parts sized to furnished Templates
] Construction per slide/keyed-together design
] Skids vertical. Maintain 10” Center-Line to fit Launcher
] Dihedral OK. Skids must remain 10” C/L vertical
] Closing of foam edges is permitted.
] Fillets for Fire-Wall strength is permitted.
] Location & attachment of Electronics must be compatible with the FB-Delta Launcher.

Judges and Judging:

] Judges will be positioned behind the dead line at pylon #1 and pylon #2 perpendicular with the pylons.
] Three Counters assigned, 1 per plane, will count 10 laps by sounding a horn.
] Judges at pylons #1 and #2 will monitor all aircraft for dead line faults.
] The official Score Keeper will keep record of that days’ heats. The race director(s) will keep & maintain.

Safety on the Race Course:

] Only Pilots, Pilot‘s Counters, the Starting Official and the Starting Official‘s Assistant are allowed on the field during a race. All other Pilots, and spectators must be behind the ‘dead line’ .
] Pilots and Counters must remain in the Pilot position until all aircraft have landed.
] Any member of the Race Committee or any Judge may black flag any aircraft that becomes erratic or appears dangerous in flight. The Pilot must immediately land a black flagged aircraft.
] Pilots are expected to visually check the operation of all control surfaces but prior to launch.
] No aircraft is to be flown beyond the ‘dead line’ at any time. Any aircraft flown over the ‘dead line’ is immediately disqualified. Only Judges are to make this call.

] Heat points are awarded as follows: First place – 4 points , Second place – 3 points, Third place – 2 points, No points are awarded if the aircraft did not complete 10 laps.
] Penalties for cuts: 1 cut – only 1 point awarded regardless of finishing position; remaining Pilots finishing position increased, 2 or more cuts, 0 points awarded regardless of finishing position; remaining Pilots finishing position increased.
] Race Day Winners: The three Pilots with the highest point accumulation of the day (three heats) will receive awards for the day. Ties will be determined by a 10 lap fly-off or coin flip, by the mutual agreement of the Pilots
] Season Winners: There are eight scheduled races; season point total will be determined by a Pilot’s six best race days. The three Pilots receiving the most points for the season will be awarded trophies.
] Ties: (1) The higher trophy will be awarded to the Pilot with the most accumulated points in the races in which the two tied Pilots raced against each other. (2) If a tie still exists, the higher trophy will be awarded to the Pilot with the most points in all eight races. (3) If a tie still exists, two special trophies of equal rank will be awarded to both Pilots.
