RE: Inrunners?
Hi John,
Yes, the gearbox is a stick-type mount, though it can be firewall mounted from the front. The gearbox has screw holes to be mounted behind a firewall, not in front like most outrunners. I have HS-56's that I have loved since getting them!
I should probably get an outrunner anyway, since that seems to be the norm these days. Most 3d type foamies I see are designed for them.
