T-Motor 6mm CCW prop adaptor (2 sets) CCW adaptors to replace the stock adaptors on MT2814, MT2820, MT2826, MT3506, MT4008, or MT4006 motors for counter (CW) rotating props. Helps prevent props loosening during flight. M6 (6mm) shaft. Includes two CCW threaded adaptors. The CCW threaded adaptors help prevent loosening of counter rotating props in flight, especially if you're flying FPV near obstacles and accidently (or perhaps intentionally) brush some leaves! Lightweight, high-precision CNC milled aircraft aluminum construction, gloss black anodized. Note: Bullet nut not included, as it serves no purpose and only increases weight.
