RE: *** Ultra Sport Brotherhood ***
I just came back from flying my US60 with OS 75AX. Sure flies nice. But I miss my US1000. It had an MDS 1.48 (remember those) which led to its demise......one dead stick too many. About a year after I got it, OS came out with the 1.60. If they ever rekitted the US 1000, that is what I would get.
I had an US 40 and US 40+. Both flew great with the OS 46 of the time. You could use the OS 55AX I suppose, but that starts getting a little large. If you are flying off pavement, I would do the trikes....if you are on grass like I am, the taildragger eliminates the nose gear headaches. I have another US 60 in the box and don;t know if I would choose a different engine of the next one. Plenty of power and great vertical with the 75. I did have an inverted engine with the US 40+. Inverted 2-strokes are nothing but trouble, but just my experience.
