Whirl & Hurl 13mm version

This is the 13mm of my Whirl & Hurl saucer.

It is designed to use 13mm motors such as the 1/4A3, 1/2A3, A3, or A10. There is no retainer. Use masking tape to make sure the motor is in place. I wrap 1/8" tape to make a thrust ring on the aft end of the motor. After placing in the disc, I make another ring to make sure the motor won't come out at ejection.

Yes, there is a chance to bind on the launch rod, so make sure it is a smooth, clean rod.
