Gemini Titan Estes BT70 Clone
 

I started this build many years ago, but put it on the shelf as I did not want to tackle the motor mount. I tried cutting out the canted centering rings my self, and was not happy with them, so ordered some from erockets/semroc, and a Wrap from Accur8, so was ready to complete. While I waited on the wrap to get here I started the motor mount build and then found 3d printed trusses on shapeways. It came in yesterday. Unfortunately it is not spaced the same as the stock centering rings so I ended up having to manually adjust them anyway. Looks like it all turned out ok, now I just need the initial paint coat, and then the wrap.

How do you plan to do the fins?

I bought the clear fin unit off Ebay,

Unfortunately, the acrylic weld evaporated, so I can not glue it together yet.

Heh, I bought that same fin unit, and the glue bottle was empty also. I ended up using CA, and after 2 launches, they're still on solid.
