Now that the st V60 is old hat compared to the new PA and RO Jett engines . Are there some standard engine setups for the stV60 to be used in a 700 sqin. stunter? Such as venturi size ,target rpm,Prop dia. pitch  best nitro % and oil content and type.etc. I can't go with a modern eng yet so I would like to run these two that I have. One will go into a Strega and the other probably a china clipper. Thanx for any good input as I would not want to waste time reinventing the wheel.

Thanks Randy , that is what I was looking for. Is this #14 venturi one of your propriatary venturis or is there a generic size that this coresponds to?  Would an Enya #3 glow plug be a good choice? Is the PA 65 RE and SE a direct drop in replacement with similar weight and a bit more grunt.

Hi

Yes the true venturie size is a number 14 precision drill size. if you use  restrictors on the engine (tube with a spray bar going thru it) you would use a .290

The Enya #3 will work well, as  will the Glo Devil 300, T Bolt RC long, and several others, you just need a hot plug.

The PA 61 and 65s are slighlty smaller but have the  same mount size so they will drop in where the  ST60 came out. They do put out much more power, and a lot smoother.
