Not a bad aircraft but it won't even look at short field !.
The Whole thing about the DR400 is that it will fly a good payload out of a short strip , cruise fast and land safely on a short strip.
There has yet to be a modern light aircraft to come close to it ( some Miles aircraft may be able to give it a run for it's money ) and this is why the metal aircraft brigade have not been able to kill the DR400 off !.
I suspect that the DR400 production will end when a new Carbon composite four seater hits the market , I find it no coinsidence that the new "Magnum" looks for all the world like a high tech Robin.
