Just wanted to tell you guys the experience of my JC EVO engine.. I have been running a JC EVO 120cc twin on my 36% sbach for testing.. It replaced an old 3w 106 TOC.. Already more power!! The engine is lighter in weight as well..The cylinder deign is totally new and the latest version and is like none other. I truly believe they will be the flagship china engines.. It has touch more power than the similar 111cc china engine and is lighter. We have also tested the 23cc and 30cc with great success and am currently working on testing a 60cc single!!. All have a billet 771 machined crankcase and as always includes standoff mufflers, ect. Below are videos of me piloting the JC 120 and JC 30. Enjoy..
