This is a resin kit - If you have not worked with resin I suggest you research the different building techniques. The parts may require some sanding in order fit properly. You must use either two-part epoxy glue or cyano (superglue) adhesive. Both of these work well, so it is down to individual preference.
The Hornet-powered Ha 137 V1 first flew in April 1935, followed the next month by the V2, and both were shipped to Travemünde that summer. It quickly became apparent that the Hornet engine was so large that visibility during diving was greatly affected, and the RLM then suggested that the third prototype be completed as a 6b with the Kestrel, delaying it slightly to change the engine mounts and add a somewhat odd-looking radiator under the nose. By this point the definitive requirements for the dive bomber program had been drawn up, taken directly from Junkers' description of its own entry which had already been selected to win, calling for a two-seater arrangement. The Ha 137 was thus excluded, although realistically no other design had a chance to win anyway.
