Some more intel..
Talked to Tony @ Merit again today for some time.
They have the upcoming F-86 and Me-262 on display on their booth as well. The F-86 should be coming out in the next couple of months. The new 109 will be coming out september'ish and the Me-262 will be later this year likely.
Regarding the Harrier, he did not have time to put it together this morning. This is the 2nd model apparently, the other went to China already. They are having some issues with it, and everything is taking longer than expected. This project started 2 (!!) years ago.
Tony hopes to have it put together by tomorrow, so hopefully!
The parts do move, and they are putting in removable panels on the fuselage so you can see it in action. The turbine spins as well when I blew it (LOL).
They are also working on expanding their 1/16 offerings and maybe 1/18. Nothing new expected from BBI at the moment.
