Hi all,
new member today, what a great site.
Anyway, just took delivery of a World Models Extra 300s , 80" span.
The quality of this artf is unreal.
Question I have is, they recommend an O.S. 160 for it.
It's about 14lb in weight and the book says it
will pull vertical from a prop hang with this engine.
I would like to fit petrol, but equivelant power to the O.S would
mean an engine of twice the weight!!!!
Any advice would be greatfully received.
