Title: RO Jett 40
Post by: Joe Danker on May 19, 2020, 08:17:24 AM
I am finally getting around to putting this to use. Does anyone have any propeller and fuel/oil recommendations? And do you think the brodak P-40 arf and eventually a vector 40 are a good match? Thank you

I run 11/4.25 bolly 10 nitro 18% synthetic oil in mine. 11/4 or 11/4.5 apc will work also. George

   It would go good in a Vector 40, and the minor modifications to attach the pipe would be very simple.

   Unfortunately, I have never run the engine and I only helped a bit when Billy and Bobby were having problems with them at some NATs or team trials - maybe the 2003 TT.  I loaned Bobby a venturi and he promptly turned around and beat me with it. I would only be guessing at what prop to use, I would probably start with 40VF-type settings except for shortening the pipe by maybe 3/4" (since I think the exhaust duration is 136 degrees instead of 145).
