Descon 4 Matrock Original Design / Scratch Built

Scratch - Matrock {Scratch}

Contributed by Matthew and Chris Taylor

Manufacturer: Scratch

I just down-loaded RockSim from Apogee. My brother keeps bugging me for another rocket (he is 10). So while messing with the program I said, "Make you a deal. You design it and build it and I will buy all the supplies to build it."

He said OK

I come back 30 minutes later and he's got this rocket on the screen.


I say Cool rocket and to my amazement it is STABLE in the sim :-)

I bought the plywood that night (we made it strong) and I already have the 3" tube for the NC I already have the foil cardboard and foamboard to make the nose cone and we will gut a viking for the MMTs

We are going to try and build it on Wednesday with epoxy He learned CA now I will teach him with epoxy :-)

Next week my 7 year old sister will design a rocket under the same terms

When she say his rocket she all of a sudden wanted one to :-)

My Brother's name is Mathew and he is 10 years old My name is Chris and I am 22

After making his design I went in and added the CR's and Parachute BUT he designed everything else and HE is going to build it I won't have it any other way

And whether he believes it right now or not he will enjoy it that much better when it lifts off on 2 C6-3's :-)
