If you are using a hopper tank the foam clunk is less of a need - depends on size of the hopper but I would suggest using it in main tank.

Engine Mount - Dont care what anyone says - those Dubro ones are gash..
One must remember that the engine mount required is based on not just the engine but the airframe... If the C140 was a 12lb plane and built like the preverbial brick sht house then its less of an issue...

But its not - and the surfaces are HUGE which means your servios need as much protection from vibration as your airframe does !


A few pages back I suggested a solution to avoiding the rudder closed loop interference with elevator...

Luke is right 60 is fine for most 3D, but to have a third setting with 85 provides you with some great results for specific manouvres..
