This has probably been done before, but here we go. The parts bin has been raided for landing gear, and I'm scratch building radiators and an oil cooler. There were a lot of cooling lines on the outside of the real one, and even on the floats, so I figured it would need at least two. One under each wing, and the oil cooler will be centre-line. The putty in the oil cooler is simply to block the see-through effect.
It will be over-all silver, so the black base has been done.
