You know, a weapons roll bar atop a D-7 makes a lot of sense. Has that muscle car-spoiler effect.
A friend of mine once dreamed of an Estes like D-7 with two extra warp/graph units above the impulse block on the two 'fins' that hobby rocket came with...
Yeah that would look awesome
i think theres a design like that on www.shipschematics.net
in the Klingon section
