Important Note


Space Derby Rules


1. The hanger’s rounded end must point forward.

2. The hanger must not protrude into the rubber-band chamber.

3. The hanger must be very firmly glued on.

4.  Groove for rear dowel is deep enough so dowel does not twist when rubber motor is wound tight.  Do NOT glue the prop nose cone so that rubber bands can be replaced.

5.  Lubricate rubber bands in castor oil or a glycerin/soap mixture.

6.  Propeller nose button is lubricated with graphite.

7.  Fins are accurately aligned so rocket flies straight.

8. Scouts and parents wind the propellers clockwise.


All rockets must pass the following inspection to qualify for the race:

1.  Only basic materials supplied in the Official BSA kit may be used. The hanging device supplied in the kit must be used.

2.  The rocket body may be no longer than 7 inches, not including the propeller and fins. Width 2.75 inches -Two rubber bands per rocket.

3.  There are no restrictions on the weight of the rocket. The rockets may be detailed in any way as long as it does not exceed length restrictions, is flight worthy, structurally sound and does not interfere with another rocket during the race.

4.  Scout may use graphite powder between the propeller and the bushing if desired. Other forms of lubrication are prohibited.

5.  Prior to each race, rocket numbers and lane assignments will be announced. Pilots are to wind their propeller up to 80 winds then give them to the race official and then take their position at the finish line. Upon completion of the race, the race official will give the rocket back to the pilot.

6.  At registration judges will assign a number to the rocket and separate it by Den.

7.  Once the rocket is submitted for entry, no further adjustments can be made except in the case of mechanical failure.

8.  The race will be a round robin followed by single elimination rounds.

9.  Any entry that experiences a mechanical failure will be allowed to re-race if it can be repaired during the same heat. It will count as a heat loss if it cannot be repaired prior to the beginning of the next heat. All repairs of this type must be done with a race official observing and certifying as to its flight worthiness.

10.  The fastest rocket to the finish line is the winner.  In the event that all rockets don’t reach the end of track, the one that goes the furthest is declared the winner.

11.  One Rocket per scout
