I bought the Funkey JetRanger fuse before Kyosho came out recently with the Nexus specific JetRanger fuse so I was committed to do it. My suggestion: get the new Kyosho one if you are interested in this style. What a job, definetly not to do if it is your first scale project. I haven't opened it up yet but it hovers fine and is quite responsive. BTW I have in the past put a Nexus in a Century Agusta 109 fuse and it fit quite well. The Jet Ranger 30 size is really snug though.
