Unless I am misunderstanding you, I am almost positive that the STH-10 has rectangular ports with round scallops as well.holler wrote:It already has the intake on the bottom. The only iffy part is the fact that the ports have rectangular cutouts with round scallops, instead of having round ports altogether.dilloncarpenter wrote:The Thunderbeam rotor/stator/motor is exactly the same as an STH-10. To convert a T-beam to an STH-10, all he would need is a bottom intake and 12 horns, which I'm assuming he already has or is in the process of getting some.coop866 wrote:Why would you do that?
