Czech Rapier Motors

[RocketboyG80]

Did anyone see these motors auctioned on Rocketry Online? I never heard of them. The seller says they come in 10mm x 40mm size with a 19 second burn and 12mm x 50mm size with a 18 second burn. Also, there is no delay or ejection charge. The seller says he taped one on top of a Holverson Silver Hawk and hand launched it. In the pictures there looks to be something like short fuses in a little bag. Does anyone know anything more about these motors? Are they something worth bidding for?

Sounds too good to be true.

I think I know what you are talking about. They are like Jetex motors, but single use. They are not intended for rocket use, they can't even lift their own weight.

What is the fuel for these things?
