Sirgun

On the noise issue, the UK is a small area compared to the US and therefore we are nearly always in the vicinity of someone so noise is an issue that cannot be ignored, our flying fields are normally a hired farmers field full of sheep excrement that hardens well if not wiped off immediatly, I think it would make a good resin substitute for glassing.

The 3A does not have a pipe tunnel but the bottom of the fus is a fibreglass half round all the way to the tail so it would not be a difficult job to install one. The whole of the blue area in the photo.

Weston Uk are the manufacturer of the Hype, Tigershark, Magnum and Grove and the soon to be realeased Obssesion a 90 size patten ship. They tune Webra's in the two stroke range and Magnums in the four stroke range, there 50TI produces 3bhp at 22.000rpm the Magnum does over 200mph, I have the Tigershark with this engine and it does 150mph no problem, the trouble is on a pipe this is noisy, in fact I have been asked not to bring it to our site on a Sunday. I fly it during the week for a bit of an adreniline rush, and the sheep do not seem to mind the noise, and there are no walkers around. (red socks brigade)

Our paths have crossed on a number of sites but I do not know what you fly?
