Am installing the OS 120 surpass in my 1/7th sizeP-51, just need some feedback on whether I need to install a soft mount for this engine?

My kit comes with the ajustable engine mount, (GP60-120) is this OK to use? I`v been told by the shop I bought the kit from It`s a very good mount !!!

I`m concerned about the vibration this engine might produce !!!!

Also is there on the market a 4 blade prop that can be used with this motor and plane? Like the look, more real to life!!!!!
