Second build - generally like the way that it turned out, especially the RunCam Sparrow which was a huge upgrade from the cheap cam that I had in my first build.. The propeller guards are a must have and have proven to be surprisingly durable after several hard, noob-style crashes. ESC / flight controller are the stack from the Lizard95 but I would not recommend it with the Lora frame which relies at the stack as a structural member. Unfortunately they cut the standoffs short which meant that I couldn't fasten the top of the frame. Long story short, had to pull the receiver to get at the standoffs below and in the process wrecked it b/c they soldered it on with like a million pins (fortunately scavenged backup from first build).

At the current time I'm working on the PIDs and have made fair progress on eliminating an oscillation. Also working to get 4 of the same motors - 1 of my 10,000 KV motors for this build was DOA so had to scavenge an 8000 KV from the previous build. Not sure how much this is contributing to the oscillation but hope to fix soon.

UPDATE - Major development in removing oscillations by turning on dynamic filtering in betaflight 3.2 - to the three people who will read this post, suggest that you give it a try because it was transformative on my little flyer!
