As one of the many step to get approval for flight in the end, the fuel boost pump performance must be proven under worst case conditions. We achieved this today, besides putting some fuel into the tanks for the first time.

Made good progress towards first engine start. Which we were unable to do as it also rained out a planned full day of work.

So we still got to do some stuff inside the hangar, such as documenting the various control deflections and measuring distances.

As was to be expected, there was some troubleshooting required to get all the avionics to play together nicely. I’m glad to report that practically all the snags could be worked out and we had only miswired two pins (serial TX/RX swapped). Out of a zillion pins, that’s a pretty good feat I would claim. Most of the issues were related to software configurations and sometimes bugs, that will have to be fixed with firmware upgrades. However, there are no showstoppers and nothing that would keep us grounded.

Support by Advanced Flight Systems and Vertical Power is excellent, with very short response times and positive replies.

Looking forward to fuel system stuff and first engine start coming soon!

Beginning of March, winter really came back… So for the first two weeks, there hasn’t been much progress at all, safe for a few hours freezing in front or even inside the hangar. However, spent lots of time on paperwork.

We are currently configuring the complete avionics package besides the other finishing work.

Some stuff like a custom Mass&Balance pic or the % horsepower graphs are a tiny bit more work than just the setup menus.

So to share a bit, here’s our Mass & Balance “AIRCRAFT.AFB” file and a % Power chart courtesy of John Goldsmith for an IO-360-M1B and similar engine.
