Going to continue flight testing the new mini slender delta. The 5x4x4 are nice, but my old abused 650 already runs out pretty fast, and it's even more inefficient with this prop. Not getting much high alpha either. Part of that is still throws on elevons set them up much like last time, so some ok throws but not full. Going to try a few different props and compare. I've got 5x3.7x4, 5x4.5x2, and 5x3x3 that I had used on the previous version. Time to do some science 🔬 🤓
