I personally don't bank on the simulator.. it's a great training aid.. but as far as changes in handling or whatever, I'd rather see that in real life.. last weekend, I spent saturday trying different blades on a heli to see how they acted and what I liked. Surprisingly what I thought I liked, wasn't what I really liked when I tested a couple of sizes..

I'm going to play with some other stuff this weekend, just misc stuff, but I'll see how it changes the heli..
