Hi Tom,

Yeah, I think that they could be personal add-ons by the builder as well, or maybe something that is available ONLY in Japan ?? Have a good look at these other two videos by the same guy and in the short one which just shows the prop/sound module working on his bench, you will notice he seems to unpack it from a separate box, which does show 'DeAgostini' on the box, so I am more inclined to say that it is an extra that DeAg are providing over in Japan maybe ?? I also think that it must be a different engine from the original metal kit one, as it looks like a complete unit in grey plastic and the rearmost cylinders look like they are half moulded into the firewall, whereas the metal ones in the kit are complete cylinders front and back, so I think it is almost certainly something of an aftermarket option in Japan. Also in the first video that I put up in my previous post, you will note that he has the engine running within the airframe and ALSO has a highly detailed engine next to it on the bench, which I think is the original kit engine and he intends to display that next to the aircraft ??
