Could you take a look at the part costs of OctoSat components? The parts seem rather overpriced, with a single fuel tank costing the same amount of money as my early game Minmus science probes.

Could someone tell me how to use the Hyperblast scramjet? I tried jumpstarting it via pushing the plane up to 22km and using two Whiplash ramjets to speed it up to 1.2km/s but the scramjet gives only 9.8kN of thrust and it can't keep accelerating to increase the scramjet's thrust further.
