Yep I'll be doing something close to that and the one from Elite. Btw I made some upgrades/fixes:
Speed is measured in c and I've also modified the rigidbodies to have a cosmic speed limit according to the lorentz factor (i could put up a short guide if anyone thinks that one could find it useful). It's not 300.000 of course but about 7000 units per second (one unit is about half an armor module).
Now the warp drive is the only way to travel faster than c, and the default speed appears to be 3.57c. I should add a way to tweak that once you're at warp. I'm thinking the lowest warp speed should be 1.5c then you can add warp coil modules to improve the max warp factor.
Oh and shields will have to be deactivated to allow warping. Those high quantity tachyon emissions completely collapse the warp field.
Mass is adjusted so the mk1 command pods weigh as much as 2 double decker buses and are supposed to be about the same size too (5m*5m*10m).
Acceleration is really in sort of arbitrary units arm, probably gonna convert that to Gs.
