Hello, I will soon be purchasing an Avistar RTF. I'm 18 and had a Tower Hobbies trainer years ago. However, one day while cleaning the fuselage in my yard, my brother hurled an apple out his window! Well, needless to say the fuselage was destroyed

Oh well. Nevertheless, I have decided to get back into the sport! I have always had a fascination with anything that flys!Anyway, I will be buying the Avistar RTF shortly. I was wondering, however, if anyone had a great experiece with another trainer. Although, I love the idea of the semisemetrical arifoil(in fact, I think everyone does). It's 299.99 which I think is very reasonable. It seems as if this is one of the most popular trainers out there ( though a downside; who wantS to be like the rest of the crowd?).
I was simply wondering if I should be aware of anything concerning the plane. In addition, I have a Tower Hobbies .46 from my old plane. If I feel the need for speed, could I replace the .40OS that comes with the Avistar and put in the TH.46?
ANY RESPONSES WOULD BE GREATLY APPRECIATED!
