After losing several spinner cones for my 15e and S 15e, I went searching for a more robust solution. I found the DuBro Black 2" Nylon Spinner (DUB273) for $3.89 works great. With the stock Apprentice prop you have to take a little bit off of the openings on either side for clearance, but with the Master Airscrew propeller it works without modification. The 2" spinner is a bit bigger than the stock spinner, but looks just great in my opinion.
No more looking for that lost spinner cone every time I nose over!!
