Hallo Boys,

I`am in the process of aquiring a Matt Robbe Rubin and thinking of going to compete at the BPA event in Apopka this year at the Tangerine.
I`am absolutly new to these engines as i started flying rc in 1994 just the end of the era of the screaming 60`s,but man i love those!!!.

Anyway the question is"Is the latest YS long stroke 61 class engine(is it the YS61AR??) more powerfull than the OS 61 Hanno ringed version??,sorry if maybe this isn`t the right thread..!!.

Thanks for your help.
