I have seen a couple of them at the field and from what I have seen the 1.20 would be over kill even for me. I saw one with the Saito 1.00 and the other with the OS .91 and they seemed about right for the plane. I know Joe, me holding back on the power?? I feel it's more of a weight thing though because it is lightly build and doesn't need the added weight or vibration.
