 I think there is a lot of truth in what you are saying. Remember C the trigear was an afterthought and probably put together quickly to get the sales. And that was before they had ironed the bugs out of the mono.

 All the same C I am always amazed how strong especially the main legs are. There are always better solutions C but at the end of the day it doesn't really make any difference. The only perfect aircraft I have ever seen is the Stemme 10 motorglider C and maybe that applies to high performance gliders in general.

 That was the other undocumented change.  Nah C it has the same look

 and feel as cast iron C and it weighs almost as much.  I was not

 entirely serious. 

 Nevertheless C it doesn't appear that someone tried to design it with a

 high strength/weight ratio in mind.

 Just compare it with the amount of material and weight of the main gear.

 The main gear has an axle supported on just one end C with a leg barely

 thicker than the axle itself. Now look again at the nose wheel. Weird

 isn't it? It looks like the designer thought that the nose wheel was

 going to do all the hard the landing work C and the main gear was just

 there to prevent the plane from falling on its side after the landing. 

 

 The whole nose wheel assembly is definitely one of the less well

 developed area's of the Europa C just like the area of the cowl right

 above it. It looks like the original designer worked from the tail to

 the nose C and at about reaching the firewall C he just had enough of it C

 and delegated the rest of the design to someone else.
