I put on the wide and narrow fuel cowlings with medium CA along with the conduits. The wide cowling locations are marked on the shroud and they alternate with the narrow cowlings. The shroud markings suggest that the cowlings go higher up, but all the pictures show that the cowlings extend below the the cradle ring, so that is how I mounted them. The stringer lengths also match this placement. The stringers went on with thin CA. My model stands about 33.5" from the engine hooks. (It is difficult to make the model stand up straight right now, because it is top heavy.) The advertisement says that the model is over 34", so my model is a slightly short. I still have some more surface detail to put on the first stage.
