(For some reason the e-mails I sent you were rejected.) I have some questions regarding your engine plans. Thanks, Bill R. RV-9 SN: 90737 -----Original Message----- From: owner-rv9-list-server@matronics.com [mailto:owner-rv9-list-server@matronics.com] On Behalf Of Rob W M Shipley Subject: RV9-List: Rv9 Vertical stab offset. --> RV9-List message posted by: "Rob W M Shipley" I am intending to fly my 9 with an O 290 initially. This is a low time engine which I got a very good deal. In the long run I intend to assemble a firewall forward Mazda 13b installation. Since the prop will then turn in the opposite direction I am unsure whether to mount the tail with the normal inbuilt offset and then rework this late. This is possible??? Or mount it straight down the axis of the plane and use tabs to adjust. I know that Bernie Kerr is building a 9 with a 13b. Are you out there Bernie. I looked for your progress on Tracy's site and found nothing. This isn't intended to be a debate on the merits of different engines just a howto on the v stab alignment. ;-) Thanks guys Rob Rob W M Shipley RV9A N919RV Fuselage - now a canoe!!! ________________________________ Message 2 _____________________________________ Time: 08:11:42 PM PST US From: "Dean" Subject: Re: RV9-List: Rv9 Vertical stab offset. --> RV9-List message posted by: "Dean" Todd and Rob I am also building an RV-9A with the 13B engine and like Bernie Kerr, I am using the Conversion Concepts engine mount and RWS RD-1A. The mount has a 1.5 degree left offset built into it. I have also considered remaking the F-981 vertical stabilizer attach bracket to give the approximately 1/4 inch offset to the right instead of to the left. Bernie may be flying his before I have to make that decision. I also plan to use the Sam James cowl.
