Title: The Evolution .52 R/C conversion.
Post by: Perry Rose on November 24, 2019, 10:24:24 AM
  I found that Evolution made a .52 r/c engine and I wanted a cheap .52 so I bought one. And an even cheaper ASP .52. This is about the Evo .52. I had Jim Lee make a true venturi and an adapter for the n.v.a. I've run it enough to say it's broken in. It has a cough in outside corners. [ I have it on a profile] The other day I likened the cough to the Fox Burp. I took the engine apart and fit a thinned piece of popsicle stick into the bypass just like on the Fox. I flew it this morning and the burp/cough is gone. There is no power loss and fuel burn is the same.
  I don't know why I'm writing this as I'm the only one using the Evo .52 r/c converted to control line on a kit built Pathfinder.
  It is the same crankcase used for the .60 c/l engine so it's a bolt in swap.
  I have a .60 on another profile and I'll evaluate it's performance and do the popsicle stick thing if necessary.

The Evo .60 on my warbird profile runs perfectly so there is no need for any mods.
