nice snug fit for 8.5x20mm motors as OE on hubsan x4 c/d models. the board fits nicely on the underside tucked away. Flies great. This setup is 29.3 grams w/ a 350mah battery. I used micro jst connectors for each motor as well for easy swappage. I have a picnic quad micro fpv racer carbon fiber/birch frame w/ motor mounts using micro jst's as well...that comes in at 29.7grams without a battery!! love the design here. great job!!
2 shells pla at 210C. i haven't gotten great results from the printer just yet on any of my prints having only had it 2 weeks. but this certainly flies great!!
