Well, there is currently the famous goldhead OPS .60 Super SPP VAE on the big auction site for sale – NIB!
That is the most powerful .60 aero engine ever built commercially available. Unlike the .65 sized version the OPS .60 goldhead is FAI compliant.
It is also one of the most handsome engines there is, in my personal opinion. I tell my buddies who've never seen an OPS that it is the Ferrari of RC engines, which they are willing to believe when they see it run. Or insert brand of your particular choice, but you get the point I'm sure.
