The real Seneca II

This is a model of a Piper PA34-200T Seneneca II. The Seneca is made by Piper since the early 1970's and some 4500 were made since then. It has six seats in a pretty large cabin, two turbocharged counterrotating engines producing 200hp up to 12,000 ft. It cruises at 170ktas in 12,000ft at 65% power. Certification for flights into known icing conditions and the nice single engine behaviour made the Seneca a popular multi engine trainer.

The model was built using the Pilots Operating Handbook, a real Seneca (D-GEJL) and some flight performance data derived in real flights.
