Yeah, its gonna need substantial nose-weight for sure.
Its a ZAIM-68. The Z standing for something that is in development before it becomes X-perimental. Since theres no evidence that it was ever produced, its fair game for FF/FS.
No points for markings & colors though.
From the proposed design dimensions, it looks like a combination of a Genie motor and flip-out finset, a Bullpup warhead and control section, and a Falcon seeker.
