Follow up to my post-> EZI-65 (heavily customized) on I115; is it too heavy?
So I managed to get two engines, but ended up using the 38mm DMS I175 I got from @jmasterj. I flipped back and forth but ultimately decided not to put my gopro in it for this launch. I got delayed from October because of poor weather, and finally launched today. Funnily enough, some things still went wrong: the motor adapter that I bought from apogee for a 54mm to 38mm engine mount didn't fit the nozzle of the DMS motor... SO I ended up friction fitting to the motor adapter and using the motor adapter to fit it in the 54mm motor mount. It was pretty solid. The second thing that went wrong was something went wrong with my code for my flight computer (I think I may have left some test code on there and that interfered with the flight computer's ability to trigger the ejection charges for the main)--but luckily a third mistake somehow had a positive effect. The last problem was not enough resistance on the nose cone to hold the payload bay closed until the ejection charge fired. @waltr had pointed out that could happen and I should mention that when I do my cert (thank you), so that was a fortunate mishap. All of these are things I'm going to look into fixing before I fly it again, but I'm feeling super confident.
At the end of the day, I still got my L1 cert. Thanks for the advice and support!!!
