I'm assembling a World Models Cap 232 .40 size ARF. I have a question as to how to mount the cowl. I want to preserve as much of the cowl as I can, but the silencer is too large, and the cowl will not fit. Should I try to find a Pitts style muffler? Would the extra ventilation be beneficial, if I did cut out an area for the silencer? I have an Evolution .46, and as of right now I have it at 90 degrees, exhaust pointing down. Any tips would be appreciated!
