I remember building this as a kid

I often don't click on links, sure glad I took a look.

That is SO COOL!

I remember when that came out in the mid 70s, it was called teh Flap Jack.  The guy who ran the hobby shop outside of Little Rock A.F.B. was named Jack and he had a built one behind his register.

About the same time the Gooodyear Blimp model came out too.

LOL, I like the little Monagram logos beneath the wings

I had two of those at one point. When they were both working, they almost shook themselves off the shelf they were on.

Ah, memories!  I am so glad to be getting back into model building!
