A word of warning -- you may be designing a bit weak on the engines. Our original lander only held 8L of peroxide, and it used four 30 lbf engines. Realize that all your engines won't be firing equally, which reduces your lift capacity, pressure will decay with blowdown, and it sure does make flying the vehicle easier if you have at least a delivered T/W of 2 at the end of the flight. What is the current plan for landing gear? I just ordered some mroe wire rope isolators for our tube vehicle. I think the multi-axis absorption is just about ideal for a VTVL testbed.
