Keep me posted when you start building it. From what I have done so far I would say it just the opposite of a fast build. There is a cazillion pieces and this is an older design. I modified my fuse to have the front formers build around an engine box instead of the using the engine rails. I didn't want to mount the engine upright as it willprotrud through the cowl. Now it will be mounted at about the 7:00 position. This took some thought and scratch building. Since you are using a radial I would guess that you will be doing some else.
