  • Ys 91SR

    I am thinking about putting a YS91SR (long stroke) in my t-rex 700...does anyone else out there run that set-up....do you need to change the gear ratio..or run larger blades?

    Cheers

    Couple of guys running the YS91SR/Rex 700 at my field - best setup IMO

    Add the Kasama header for a boost... not like you'll need it!!!

      I run a pair of 700's on YS91SR, Hattori mufflers (the one specially for the YS) and 30% optifuel and got to be one of the best set ups.

      Main blades I use are the 703 Maniacs.

      No need to change any gear ratio, just build, fly and enjoy.

      Simple!

        Running the YS with a 946 hatori and 710 Stick bangers.
        Great setup.

          Running mine with the same pipe as Adrian and using Thunder Tiger BBT 680`s

          I have a set of Radix 710`s but never tried them.

          Great little engine
