Maxx Prop Adaptor 2.3mm(0.09") motor shaft, 3/16" (5mm) prop shaft, Bullet Nut, Collet Type

Note, this type adaptor is intended for small props and does not have enough motor shaft grip to hold high power 3D applications like 11-4.7 and 12-6 props. However, for props in the 8" and under category it works well and offers a very small shaft diameter so less prop drilling is required.
