i like the idea of making different thrusters with different speeds take the cheetah thruster for example.... 20+million... completely useless Why? doesnt make that much of a difference.
now also the name of that thruster should be changed indeffinentely. that thruster is made to go the longest right now. a cheetah in real life is one of thefastest animals in the world but when it comes to stamina it can only run at top speed for 13 seconds before it keels over with exhaustion. so i think the name of the thruster is rather silly. but if it had a higher thrust speed i.e 220-240 but double drain or such it would be alot more believable
