LIRVIRTIRC 8 Years And Above. Material: high-strength PC. Hole: 5mm. Outer diameter: 60mm, 70mm, 80mm. Steering: CW, CCW. Function: big thrust, big torque. It is suitable for 5mm drive shafts, please measure the diameter of the drive shaft you are using before purchasing, and then choose the propeller that fits the inner diameter of the hole. This propeller has a very large thrust and is currently the most powerful 4-blade propeller. However, when the thrust is large, there will be corresponding requirements for the motor: 1. Very large torque is required, such as 895,997 brushed motors, 2. If you using brushed motor, it is recommended to use a motor with speed below 8000RPM, such as 895 or 997 motors. If you are using brushless motor, it is recommended that the speed be below 1000kv, such as 4260 brushless motor
