Plan Ahead - The Tazz Engine Mount #7282

There's a good reason why instructions say to read them all the way through before starting construction. Sometimes you have to make adjustments. Dry fit everything before squeezing out any glue!

   

The engine block and centering ring placement on the Estes Tazz instructions can be confusing. 

In the instructions the engine block (Part B) isn't butted up against the upper bend of the engine hook. If glued as shown (even with the tube end) there will be a 1/4" gap between the hook bend and the block. You want the engine block touching the top bend of the hook otherwise the hook could get loose after a few flights tearing into the tube.

The instructions show the centering rings glued directly over the 1/2" and 2" marks. There isn't a side view drawing to double check things.

If the rings were glued over the pencil marks there wouldn't be enough space between them for the supplied 1 1/4" wide streamer. Sure, you could cut down the width, but I'd rather have as much descent drag as I can get.

Dry fit the parts before using any glue on the rings. Use the streamer width to set the space between the rings. The upper ring will end up higher, closer to the top bend of the engine hook.
