I know good and well I am going to get seriously flamed here but I'll say it any way.
If your just flying for fun, any old handle will make the plane go up and down. That said, if you want to get the very best performance out of your plane and compete an any level, you are going to need a handle that has adjustable line spacing and hard point connections. Yea, yea I'm full of crap. But why is it that all top ten fliers at the NATs, fly with a Fancher type handle?

They are surely not paid sponsor fees to do so. All competitors are looking for every possible edge and or advantage.
When I flew at an intermediate level, I recall the big boys advising me to upgrade my handle. I thought they were all full of crap, and could not imagine a handle making any difference in flight performance. I finally caved in and tried a handle loaned to me by Brett or Ted (I don't recall) But I do recall how much better the plane flew and how much more trim options I had. Needless to say I didn't fly in intermediate much longer after that.
Its advice to take or discount. But I would try it before I discount it.
OK gents flame away!!!!!!!!!!!!!!!!!!!!!!!!
