3mm grooved shaft
where do you use it ?
Most of time front mounted motors shaft got damaged so we need another shafts but they needs to be grooved to set c clip in it.
right !, similar shafts are used all over, like in the heli , the main shaft as well as the tail rotor shaft , every crash generally distorts them bad , so like i fly the 450 heli , and need to store some shafts
This is how I groove them.
