I enjoy flying more scale like.. High speed is not a high priority with me .. I have a OS 160 Gemini in a 1/4 Scale B.U.S.A. Cub and I find that it has more than enough power ..I also have its clone , the ASP 160 twin that I haven't run yet . I am thinking about putting it in my T Craft .. I too love the way they sound . My OS 160 is my favorite motor .. When I do a low slow pass with my Cub it just makes me happy . I am pretty sure the 160 would be more than enough power for the way I like fly my T Craft ..It might fly even better than it does now because I think I would be losing some weight .. Right now I have the G26 in it . Thanks for the input on the cowls.. That looks like what I need
