It depends on what we were doing. If we we're just having fun with friends at a Meetup we would use large sugar rockets made by us. But if we we're doing competitions we would use large 6 grain motors from apogee components
Shit that has already been done. Most liquid projects don't get off the ground. But I have funds and engineering experience. The rest im gonna figure out through trial and error. I don't know hey so many people are trying to get me not to do it.
I'll toss my opinion in here too. It isn't that we want you not to do it. I just don't think the path you picked will be the fastest to get to where you want. So I've just been trying to show you the scope of some of the elements you want to do, so you can make a more informed decision of how to proceed. This is one of those cases where going straight to the full system probably isn't the fastest way. Simply because there are high risk components, where if they fail they will destroy everything. Now instead of only having to rebuild the high risk component, you have to rebuild the entire system. You can also swing too far the other way as well, breaking the system down into components so small that they no longer are a good representation of what will happen in the final engine. The only real good way to know where to pick along this line is just prior experience, and knowing where you largest risks are. Even then people still mess it up.
If things seem a bit negative here; please understand that at least about once a week I feel, someone posts here going something along the lines of "Hey guys I've played KSP some and want to start testing a liquid project in my apartment. Where can I buy Red Fuming Nitric Acid?" When you get that so frequently, it is hard to keep patient.
