Y.S. 140 question
I would like to purchase a Y.S. 140 for use in some of my larger scale planes, mainly WW2 1/5 scale fighters eg yellow Spitfire...
My question is.... What is the difference between the various Y.S. 140 engine models, I have heard of the L and FZ version whats the difference? and also which version is the most popular and why???
Cheers-
