I have been out of power flying for over 25 years but have been active flying R/C gliders. I am interested in using a modern .60 size engine. Back in the early 70's, the Webra Blackhead .60 was a great engine and so was the OS .61

Are the .60 sizes made today as good as or better than those engines? Who makes a quality .60 size motor today? I don't need the Rolls Royce of .60 size engines but would prefer the BMW of todays motors ! I definitely don't want some cheap motor that won't last.
Thanks,
S Gibson
