Bring it out to fly at the event


It would be 'eventful' to see that fly with a Cessaroin 24 mm G https://www.thrustcurve.org/motors/Cesaroni/144G65-8A/ or at least an Aerotech F https://www.thrustcurve.org/motors/AeroTech/F35W/

It doesn't seem fair to not include the original Goblin, made by Estes, in your list.  It was my first rocket with a "Mighty" D engine!

What is a Goblin?  From the Oxford English Dictionary

Goblin (Noun) gŏb′lĭn

A)    An ugly or grotesque sprite that is usually mischievous and sometimes evil and malicious
B)    A shortish 4 fin rocket, typically identified by a large motor relative to the size of the rocket.  Examples include PoleCat Goblin,  Loc Goblin, scratch built goblins, rockets with goblin like parameters.  Not to be confused with squat.
C)    A mythical lost rocket, seen , like the Flying Dutchman but never to be found.  Usually used in context with Wedge Oldham.

What is the Goblin Event

The Goblin Event will be a  'not so mass' launch of an entire range full of Goblins at June Rocstock / LDRS.  Goblins will be launched in groups each up to the safe, and compliant total ISP.  Any rocket meeting the requirements of B or C above can fly.

There will be three prizes for;

1) highest total thrust to rocket weight

2) highest peak  thrust to weight

3) Most Goblinish (decided by a board of experts)

If you want to fly in the event, email me (put goblin in the subject);

  • diameter
  • motor to be used  - include total impulse
  • rail - or rod(what size)
  • type of goblin (I.E. Polecat - Loc-scratch)

Times and details will come before the event.
