I have the new arms and had planed to use ball links untill I read what Tom said about ball links and plastic arms, backed me right off that idea.
I was looking at AirWild's MLP arms, they come in 1" and 1 1/4" but with only one hole for the ball link, so you got to pick the right one or drill a new hole if you guess to long.
I ordered the hardware kit with the Extra and plan on using the surface control horns in the kit.
Maybe I should wait untill I have the plane and test fit with the Hitec arms, then order the right ones.
Here's a link to AirWild. What do you guys think of these arms?
