The iron I’ve been using lately is the leather iron from Alibaba.com. It requires some modification, but it’s better than the Black Baron because it’s narrower (more info here: https://www.diypackraft.com/construction/tools/ ). I see they’re also selling them on Amazon now too: https://www.amazon.com/Dancing-Wings-Hobby-Temperature-LS-YD-01-004/dp/B01IQL3VBE/ref=sr_1_fkmrnull_1?keywords=RC+Airplane+Electric+Iron+Temperature+control+Iron+RC+Aircraft+Covering+Tools+Iron+for+Balsawood+Model&qid=1555636184&s=gateway&sr=8-1-fkmrnull
If you haven’t returned it, you might be able to modify the Hangar 9 iron without removing the electronics… I don’t have experience with that iron though, so I’m not sure how easy that would be. If you give it a try, please let us know!
