Magnum w/Retracts
Naaahh...
You americans are spoiled... over here we don't even have paved runways (well some, but very few actually...)... If you have a fine grass field, that's more than enough to put down a Magnum...
I've put mine down straight after a long powerless dive...doing like 60 mph... no problem...
I've also put it down tail first...doing like 25 mph... no problem either....
My point is: retracts only add complicity and weight to an airplane like this... you don't need (want) that...
