this is my second build and probs the best of the 2 so far. Great on the freestyle with some personalized stingy PIDs. A few grams of TPU were cut off to fit the cam, and the Axii mount doesn't fit the Lumenier Axii but a few zipties fixed the job. only real expensive problem is crashing on the canopy and cracking the FC. All up around 5min flight time around the paddocks and hills with lots of high throttle.
