So we're really liking the PG71 Gearmotor found in the 2012 KOP (am-0914) (i.e. the "AndyGlobe"), but we're looking for a little more oommph, so we're thinking about replacing the stock RS-775 series motor with the AM 9015 (am-0912), a higher-powered(?) member of the "RS-500 series". (Basically, we want to build the
am-2084)
1. I am correct that the AM 9015 has more power than the stock RS-775, right?
2. What do I need to use to replace the stock motor? I ordered the spacer (am-2062) and the pinion (am-2068) and I even sourced the M4x55 SHC screws that the spacer drawing says to use. But I believe the RS-550 series motors use M3 screws for mounting. Do I also need some of those, and if so, what length? I don't have the gearbox available to check for myself - it's in the bag. We're planning to do this on Thursday morning in Hartford, so I want to make sure we have everything we'll need.
Sorry for such a vendor specific question - I would have emailed AM directly, but since these are KOP items, I figured other people might benefit from the answer as well.
Thanks in advance!
