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?
