you know what was the biggest plus for me with the ops/radical engines,the reliability of them.

if the engine cut then you knew something was up,stone jammed or fuel line snagged etc..they just didnt flame out,ever.

come in after a 30-45min final and it would just sit and tickover as quiet and smooth as anything,no hanging high or burbling,awesome.

so if they remain the same with a different head on them then thats great,if they have improved them any(altho i dont quite know where or how they could) then thats unbelievable!
