seen Zinger 15X6 for sport. I have used the factory muffler and the
slimline
inverted pits muffler.

This is a bored out 61 so do not let it run lean and it will be just fine.

As far as power it pulled a Tai-Ji 60 just as good as the YS, but without
the headaches of the YS. Not to mention it is also lighter and smother
running.

Linda,

Thanks for the reply. What nitro per cent fuel do you run? What RPMs, if
you've checked them, do you get on the 14-10?
I have an old Runaround that I'd like to try a 91FX on. It currentlt has a
YS91 in it.

Thanks.

Dave
