Not sure if there is a Market. Is Avid producing kits yet? Tubing at Spruce has doubled on alot of sizes and shipping is triple I found that out the other day they wanted 46 dollars to role up a throttle cable and ship it to me so I called them to get a proforma number they got it down to 18 bucks. Frustrating when I have to do that anymore.
Nice work I should also do that to mine and see if it makes any difference. I just hit 60hrs so I would think I would be able to notice a difference Maybe who knows Right. I did that to the tail braces when I owned a Quad city Challenger And It took the vibration out of the tail But no difference on speed.
From where I'm at I can't measure for sure but my outlet is at least 6 times the size of the inlet. And it does make a difference When I was building I started the Jabiru with out the cowl Just the ram air ducts installed and it warmed up fast. After I installed the cowl I have never seen anything close to a hot cylinder. When I get home I can measure for ya and try to help any way I can.
Its a 68 inch. The blades weigh almost nothing but the center hub is about the same weight as the Tennessee I'm not sure exactly what they are but I don't think I gained any weight. Cant say anything on performance yet But with my past experience it is really hard to beat the performance a a good wood propeller.
