Just a quick note its not so many RCU members having problems with VMAR its the same one's over and over and over and over and over and over ad-nausium.
I have not had a problem with my VMar's, F4 Phantom and Arrow Tiger you get what you pay for, these ARTF are not that bad, just cheap.

I am proving an electric system in a 72" Extra 300L at the moment with a view to putting the whole lot in the Phantom this would get rid of the silencer problem.
