YS 120 help
I have a YS 120 the first version with Hatori #674 muffler. I had header in my possession at one point but may have been lost in my house moveyears ago. What will work header wise today will be going on a Typhoon also first version? Pipe/muffler tunnel runs center of fuse open to bottom of plane. The engine will be soft mounted with Gator RC mount all suggestions would be great.
