After suffering a nasty fin-break, I re-rigged my Sprint with a chute, so I go easy on the engines. It's over 20 years old, after all.

Didn't launch it today. Forgot to take masking tape to the field. Gah.

Oh man, I love the Sprint. If you check out our Cougar 660 it resembles the Sprint, only in 13mm. We provide 3 different fin patterns to choose from and one is a downscale of the Sprint type of fin.

The great thing about the Sprint is that, assuming you can keep getting it back, it is good for at least 500 flights!

FWIW, at NARCON NAR President Mark Bundick gave a session on kit bashing. He referenced the Estes TR-11 written by Dr. Jerry Gregorek. Dr. G had some of his aero students at The Ohio State University build Estes Alphas (the balsa fin and nose cone versions) with various degrees of streamlining. The fourth and last iteration had a different nose cone and fin planform, plus a boat-tail as designed by George Pantalos.
I pointed out at the Q&A that that design was the basis of the Estes Sprint.


And now you know the rest of the story...

Enjoyed Narcon!
