reminds me of the Higgins helicopter (a recent challenge)
"Helo" Ken.
This is what I found when looking for RR's challenge (Higgins) last week. Not a Higgins and it remained a project. This is the 'enclosed' version and the last time I looked there was a similar looking drawing of the 'open' configuration on the net.
Are those doodles or Sea Gulls in the top right?!
Doodles. No maritime connection with this machine. They could be eagles.
It's all good mate. Thanks for asking.
