I'm interested as well. I emailed them a few days ago asking about dimensions and weight for the tail listed at the bottom of this page. I haven't received any sort of reply yet. https://www.tangogyro.com/parts-prices.html

Did you ever hear anything else from Tango? I never got a reply. (update, they just replied to a new message) They said they'd get measurements Mon, and I'll pass along any info I get.
