Hi Ray -
Iīm joining the thread rather late - family sunday, you know
...but Mike provided you with excellent reference
You did not change the leading edge of the 210-3dz - thatīs good that way. The angle in the 210īs wing leading edge is much more pronounced than shown in Greenīs drawing. The 210īs engine nacelles were much shorter than those of the 410 due to the Daimler Benz DB 601 F for the 210A-1 and the DB 603 A for the 410 A-1. The fuselage of the 210 early variants received a lengthening of 954 mm and the engine nacelles of the 410 were about 50 mm longer. From tail to spinners the 410 was about 1000 mm longer than the early 210s.
The 210 turned out to be a major desaster for the Messerschmitt company. The 210 was pressed into service too fast and the flight characteristics turned out to be malicious and too dangerous for young pilots. The problems were overcome during the production of the A-1 series by the above-mentioned lengthening of the fuselage and other minor improvements. But this was only achieved by leaving a huge scrap heap of already-built 210 fuselages and the demise of Willy Messerschmitt from top of the company.
Many improved 210 variants flew in Africa with longer fuselages and did a rather good job - but reputation was destroyed. ("One hand on the stick - the other on the ripcord") More than willingly Messerschmitt changed the ill-fated designation from "210" to "410"
Btw, concerning the "D" variant with the so-called radial - in fact itīs a DB 603 G liquid-cooled inline engine with annular radiators - similar to the Ta 152 C. Only one example ("BN+CY") was equipped with the 603 G in the normal 410 canopy figuration. The progressive designs were to receive a completely redesigned crew compartment ( is slightly to be recognized on the 410 D drawing)
The 210 wasnīt that bad plane as it was looked upon - in fact the problems had been solved when delivery and production was stopped. An interesting story - but maybe too much for one post
If you need drawings ore something else - tomorrow Iīm in reach of my scanner in my office...
