I've read about this on the form and I can't believe you people do this! I just went into my first orbit and using the OPA makes it damn easy. I'm trying the micro tank and engine out because I wanted a better model, haven't used it yet. So tell me about how you guys do this, do any of your just do vertical lift off and landings? my orbit reentries are never smooth at all. Also, can you land the module in water and have it not explode?
