Estes Optima question
I recently augured in my Estes Optima. Seems there was a spent motor casing in the stuffer tube (long story) which prevented the motor ejection charge from kicking out the chute. I was able to salvage the bottom 18", including the fins, but I don't have the original total body tube length. Anyone have a stock-length Optima or Shadow they can measure? I have a number figured from part numbers and such but would like to compare to an actual measurement.
Thanks.

The Optima (#2035) and the Shadow (#2094) each had an airframe made up from two BT-80KD tubes (14.2" long) and a length of BT-80 11.00" long. Beautiful models.

I have a spare Optima decal if you need one and a butt-load of the metal-flake orange adhesive film if you need some.

If you need longer than the standard BT-80, Estes is now carrying a longer 23.5” BT-80, p/n 046009, priced at $5.99
Of course, BMS sells a 34” long BT-80 tube. I think it’s around $11. (I’d confirm but their website menus don’t work on an iPad ... )

It’s not an iPad problem, it’s a Safari problem (or a BMS site on Safari problem). Use Firefox for iOS (or on the Mac) to get BMS’s web site menus to work. Cropped bit of screenshot from my iPad attached. [/thread drift]

Spin fins make this a whole lot worse.
