Just want to buy all parts for a 4*-40 ARF. I will be using Futaba 3004 servos (likely from a 7C-2.4GHZ package).

My question: For the servos on the throttle, what type of servo arm hardware should I be using.

I would not have even asked but I notice on my trainer the throttle has a different type of connection to the servo arm..it looks like a vertical metal screw with an eyelet where the arm goes through....very different from plastic links for the other servos.

Also, do I need servo mounting screws too?

Tower web links would be great too! Thanks.
