elevate and traverse

[paul needham <paul.2.needham-at-btconnect.com>]

Hi all

Body underway so looking towards elevate and traverse for main gun.
As this is a Hetzer following questions arise.

1:- Is traverse a necessity ?  especially as I currently don't have 
proportional speed/steering

2:- I have the left stick set up for fwd/rev and steering and have a 
throttle ratchet on the right stick for fore and aft movement [elevate] do 
I also need a ratchet for the traverse ?

3:- I don't have any special servos [ 1/4 scale/heavy duty ] will I need them ?

4:- Do I need servo savers to prevent damage ie stabbing another tank or 
part of the scenery with the gun whilst the tank is moving ?
  lots of questions but getting exciting , gun is in post whoa !!!!!!
