dude log some hours on some one else's trainer if you can before you fly the fourstar. I had a trainer and got board of it in about a week and had to buy something elses. I got a fourstar 40 and i love it! Now i'm building a four star 120 with a Ryobi 31 cc gasser on it. I like having a trainer around though because i do train people on it on training nights at our club. If you plan on training people in the future then i would get a trainer just to have. Just my two cents
