Rodders,

I am currently running a Webra Speed .61 which began life as a heli engine but I asked Webra if there was any difference between it and the standard Speed .61. They said that the only difference was the heli cylinder head, so I changed the cylinder head and it's now a great pattern plane engine.

I also have a NIB Webra Speed 61F Champion. Catalog # is: Nr. 1024 RC
It came with the Dynamix carb and a Webra pressure pump installed in the backplate. It is Schnuerle ported and has an oversized 17mm crankshaft. The piston is "ringed", but not baffled.
