I really would like to use this engine in a .60 pattern plane I have, so I hope to see good feedback. I too got burned on the JBA 15, I replaced it with the DLE 20. What a great engine that is. I am confident that this engine will operate well. Mainly because I do not feel Horizon would bring something to market that has not been fully tested. That being said, I will have to sit back and watch for a while to see,/hear feedback.
