Tempest Replacement Shaft for 1708 Motors
This is a shaft kit for the Tempest 1708 series airplane motors and includes a new shaft, washer, nylon locking nut, and two set screws.
Tempest 1708 Series motors are built with 2mm steel shafts that will last through countless hours of flying fun, but occasionally, on a "Less than Perfect" landing, you may bend or break one. For these occasions, we offer factory replacement shafts for all the Tempest Motors.
The shaft kit for the Tempest 1708 series airplane motors includes a new shaft, which measures 2mm in diameter and is 29.6mm long, along with a new nylon locking nut, washer and two set screws to hold the motor together. The shaft kit may also fit other brushless motors that require a 2mm shaft of this length. The shafts can be cut shorter with a Dremel tool and a cut-off wheel if necessary to fit other motors.
Note: The shafts in the Tempest motors are a slight press fit into the aluminum front housing. The shafts will not just slide out when the setscrews are removed. They need to be pressed out in a bearing press, or in a drill press, with the front housing of the motor supported in a block of wood to prevent warping the front housing. Never tap the shaft out with a hammer! The shock induced can bend the motor parts and knock the glue joints loose on the motor magnets.
If you are unsure about how to change the shaft in a motor, you can watch the How To Change a Motor Shaft video that we have on YouTube.
