Hello Red Baron,
Yes, you are right for instance the stroke of 145 mm in the Gnome was replaced by a 140 mm in the U0.
( ok in 1/32 it make a 0,15 mm difference )
The U0 have a 11,5 liters compare to the 12+ on the Gnome...
Anyway this is the best solution to start a Lambda !
In addition to the above list is the Morane Saulnier type H Hydroplane of the 1st Schneider Trophy in 1913 flew by Roland Garros.
( Garros was later killed in action on a Spad XIII )
This is the choosen solution to start my 1/32 Schneider Morane in scratchbuild.
I will later make a post on the dedicated area.
!! We still need a 9C Mr Taurus !!! ( please

)
cheers
