I was looking for the information in space.com about the date for the Dragon rendezvous with the ISS, and i saw that today will be the Orbital pegasus XL launch, i looked for a Cardstock 1:48 and i found this one http://jleslie48.com/gallery_models_postapollo.html so i modified to use a A10T Motor.
I reinforced the fins adding a little tab
And installed inside the body
Create the engine mount
I added a ejection baffle
