I enlarged wingspan for about 4 inches for much better gliding to the pits.
It proofed to be just right.
We only fly on short cut grass RC fields,
that's why the landing gear points more forward to prevent the nose-over,
and the larger wingspan supports slower landing Speeds also to prevent n-o´s.
If we have (but we don't) access to a tarmac circle ,
I just would build the L.J. like the Plan dimensions.
HAPPY NEW (GOOD) YEAR 2015
