Main engine is finally assembled, need to build a test stand, hook up ignition power source, fuel lines and Nitrous Oxide canister, and I still need to finish the build of the control board. A little at a time, seems like time is my most valuable resource. Had a good but busy holiday season, not going to make any estimates this time, just going to keep on working whenever i get the time. I am very excited with my progress, actually having the main assembly together is a big motivator. This should be an exciting year, lots more to do.
