Hi Guys,

I've recently finished putting together a Sebart Wind S 50 with a Hacker A50-16S motor. One query I do have is about the installation of the motor. To fit in this aeroplane it is necessary to mount the motor in the 'radial' way using the supplied prop adaptor. This means that the steel shaft is actually inside the model with a securing ring attached to prevent the motor dismantling itself when in use. The steel shaft has a flat spot for the grub screw of the securing ring to tighten onto. Even with the csecuring ring in place, the can of the motor and the steel shaft still pull forward maybe by an 1/8th on an inch. Is this normal? Will the collet move forward onto the motor and cause damage?


Any help would be much appreciated.
Stephen
