Hey Jeff,....

I ran an OS-160's for several years in pattern planes before switching to YS. I like the change,...the OS-160 is still a great alternative as is others (not sponsored by YS). The ARC is the best bet to do what ever a flier/builder wants to do and as I said, you can request many options with the ARF.

It's not impossible but something to work around with the ARF version. I could get a 2 stroke in mine by fitting a pipe floor under the pre-installed floor of the ARF,...not impossible. It would be very similar to making the crutch for the admidship area and rear of the plane.,...but possible. The Integral is a tight fit as well in making a two stroke work.


Best Regards,
