Silvercomet, if you are not equipped with a well stocked shop, toolchest and hours a day to spend on the hobby, I would defer the YS or four-strokes in general until later. As a high performance engine, the YS needs a lot of attention, notably checking and re-setting valve adjustment every couple gallons of fly-time. Some guys neglect this and get away with it, but to get the most out of this product, that's the deal. Also some finicky fuel questions, tank set-up, etc. that need dealing with on a YS. I would recommend you leave this until you are prepared to spend as much time learning about engines and maintenance as you are flying. Right now you need time in the air, and a simple 2-stroke will do that for you. The Venus will fly very well on a .46, so fly and enjoy! (I don't know how anyone can manage both gf and rc, although I'm told it can be done.)
