I am a novice RC plane builder and got a MKS 48" Extreme Flight plane from a friend along with a BL15 eflite motor. I then bought a 12x6 prop as recommended by Extreme Flight's website. I am now trying to mount the propellor to the motor and seem to be missing adapter pieces since the motor shaft is a 5mm smooth shaft and the prop has a 6mm hole. I assume there is some kind of adapter system? I built & flew my own plane from Flite Test already but that came with everything I need. This build requires some fumbling and my local club is not active right now because it's winter! Please help me find what I need! Thanks for any info.

I tried posting links but this site won't let me yet since I'm new.

The motor is a BL15 1260kv by eflite
The prop is a 12x6 beechwood electric prop by Falcon
The plan is by Extreme Flight and is a MXS 48" wingspan

this will do the trick.

Does your motor already have the prop adapter similar to what Speed posted? It looks like the BL15 has an integral drive hub, so all you'd need is a spinner nut and washer. If you have a means of attaching your prop and the only problem is the hole size, there's nothing wrong with making a bushing. There is no side stress on the hole once you've tightened the prop nut. All the hole really does is locate the prop in the right place for balance. I've even wrapped tape around the shaft before to make that work. It didn't cause any problems at all.
