60 degrees is absolutely fine for movement with the right Centre of gravity. Unless you take measures during the build you wont get more than this anyway before fouling the rudder cables. I had about 85 degrees down movement but have reduced it to 60 - it still does the most wicked inverted wall you have ever seen - will get a vid up of this soon.

Sprink, The YS 160 definitely doesnt fit. i will get pictures showing the differences bettween the castings of the 140L and 160DZ.

They did supply an anti-foaming clunk with the engine though - should i use this in my hopper tank or stay with the standard clunk?

As far as the Dubro mounts go they are fine, the only prob is you have to change the mount rubbers about once every 50 flights, and i personally dont think they absorb anywhere near the vibration that the more expensive mounts do. I will be getting one of the better hyde or Zn line alu mounts, as the Baron advised when i was first deciding. Should have listened to him more closely-his advice is sound every time
