While setting up a DLE 20 on my Phoenix Extra, I have the following issues
I am setting up with a 2-56 pushrod on the throttle. Decided not to go with a nyrod setup simply because its not available right now. Initially I wanted to have ball links both sides to avoid metal to metal contact but the 2-56 Dubro pushrod is one side threaded.

1) I got this Dubro 2-56 ball link locally (see pic). Its snap on type, not bolt thru. I am concerned that if used on the throttle, it could disconnect due to vibration. But guys on the field told me it will be ok. Should I trust it? I dont want the engine cutting off while I am in a hover

2) The engine came with the metal throttle horn installed and a seperate fibre horn in the box. Should I use the metal or fibre horn (or should I mount the fibre horn on the metal horn and use that)? A longer horn will give a slower throttle response but will also require less effort on the servo

3) At the field they suggested I should either put a Z-Bend in the pushrod at the throttle servo horn or use a E-Z connector (you know, the brass type where the grub screw tightenes onto the throttle pushrod). The E-Z connector gives flexibility of throttle adjustment but I am not sure its secure enough. What should I do?
