When I purchased this plane one week ago, I asked Chris about the 180. He said that his next choice after the YS 1.10 would be the Saito 150. Seeing the 180 is 2 grams lighter than the 150 and produces more power i thought it only fitting to use this engine. He also mentioned to use the left stick (throttle in this case) appropriatley. To him I replied absolutley. This engine could give this plane a new meaning to the words over powering. I am suprised that more ppl aren't using this combo. anyhow I am looking forward to flying it soon. I will post flying resuls here or on the bid EF Yak 68 thread.
