Hi, I'm a newbie to gas.

Locally many gassers are using similar linkages to their 60 sized glow planes with z bends being pretty common. However, most build threads I've seen online use a ball link of some sort on at least one end. This applies not just to the control surfaces but also to the throttle/choke linkages.

Is there any reason why z bends may not be suitable for a gas plane? I understand that over time, a z bend will develop a little slop, but then again, wouldn't a normal clevis do the same?

Is that why ball links are so prevalent?

Thanks.
