Dont mean to hijack the thread, but am I running too small a prop on my .46FX?? (10x6)
No, you are not running too small of a prop. Yes you could experiment with other sizes but the 10x6 is within the range of your engine.
To qualify this, I get PLENTY of speed out of my trainer with a 10x6, and vertical is GREAT!! (Wont hover, but it will climb almost unlimited in about 75 degree up angle, and it is a trainer after all..)
If you are happy and comfortable with the flight characteristics then everything is just fine. As you advance in your flying, you may want to experiment with various props to see if there is anything you like better but there's no need to be concerned at all about the one you are using now.
