Model Forum / Radio Controlled / Air Models / October 2003Prop mounting question (warning: ascii art)
I have an OS FX .46 and I'm trying to mount a prop onto it. My instructions from the plane kit say to take off the driveshaft nut and washer and install the prop cowl backplate. My engine comes with 3 things on the driveshaft... a big attachment-looking thing that's the same color as the engine and looks like it's the other half of the end of the engine block, a big washer, and the driveshaft nut. The driveshaft itself has a threaded portion, a nonthreaded portion, and a bigger nonthreaded portion that fits the whole in the big engine-colored block. -------------- | | (2) | ------- (1) | --------- --------- | ------- | | | --------------- (1) - nut and washer fit here (2) - engine-colored attachment fits here So where does the backplate go? Behind all the removable parts? Just behind the nut and washer against the back of the non-threaded part? Thanks for the help, and sorry for the excessive use of ascii art.

I assume you are installing a spinner. Item #2 is the Drive Waser, and is required to prevent the prop from locaking against the crankcase. Simply keep #2 on the engine, install the spinner backplate, then the prop, prop washer, prop nut, then the actual spinner. If you are not using a spinner (nose cone), install the Drive Washer (#2 from your drawing), then the prop, prop washer and the prop nut. > I have an OS FX .46 and I'm trying to mount a prop onto it.

The prop would go inbetween #8 and #9. If using a spinner, the backplate of the spinner would go inbetween the prop and #9.
