New Project - 90 powered formula one composite
Hi Guys. I have taken BobS27’s advice. I took the OS 91 VRDF engine off the 60 Mustang per his advice and am finishing a true speed project for it.
I have an old Lyle Larson Formula I composite arf from the mid 1990’s designed to fly with a Nelson 40 FIRE. I remember flying it with an OS 46 vrdf engine. It was a blast and scary fast. The only thing about it I dislike is that it is a smaller plane than I usually fly. Since my eyes are not what they used to be, I painted the wings orange and blue on the bottom surface – not cool but very visible.
I have modified it to accept either a 65 or 91 OS VRDF….. I plan on eventually putting the engine/pipe combo from the Mustang 60, which I have been writing about that has been clocked at over 180 mph by pitot tube and gps. See …page 2 or 3 or follow…

I added 5 inches to the Formula One ship, placed the gear on the fuse ahead of the wing rather than on the wing, fattened the fuse by one inch at the firewall to fit the 91, built a new cowl, and moved all of the equipment as far back as possible. The pitot tube is mounted and plumbing installed, but I won't put in the Eagletree telemetry system till I test fly her. She carries 12 oz of fuel - which should last 3-4 minutes. Plenty of time to get into trouble.
Stats for first flight: Engine: OS 91 vrdf/ prop: 11-8 apc/fuel: Omega 15% with 2 oz castor added/
I am going to attempt the first flight tomorrow if the rain stays away.
