Enima would be appropriate
I thought that was one off those Japanese Vans ! I thought I was following a 4CENT Honda up the Hill the other week , apparently it was a acent , sholda hada 'S ' .

ANYWAY Nice Plane . Always thought the olde nose stiffeners were mandatory . Good System . A bit like the old Goldberg Cosmic Wind / Shoestring / Buster .
With say a piece of 1/8 ply across the front - to allow for a bit of a radius , with a HOLE in it , you can get Cooling Air thru to the crankcase , if your somewhere a bit warm .
Another cross piece / bulkhead just aft of the engine , and the doubler opened under the crankcase .

Thought that was a .46 . Now I see its a .60 . So we see why its necesary !
