Will likely require a significant spinner cone trim.

<p class="MsoNormal"><font face="Arial" size="2"><span style="font-family: Arial; font-size: 10pt;">Been running an APC 3- blade (15-10)
re-pitched by Dave Lockhart on my Brio for quite some time until yesterday when
I nicked a tip on landing. I have also used an 18.1 x 10 with
pretty good results. I noticed that APC also has an 18x 8 W
IMAC prop and a 18x 6W 3D prop. I assume the later would be less
desirable, but who knows until it’s tried. Has anyone used either and on what
motor ?</span></font></p>
