Referring to the post-ICI Jetex pellets from Sebel, and those from Jet-X (Powermax), which I believe are dichromate formulations--are there any credible reports of successful Jetex or Jet-X flights with either of these propellants? Next week I intend to replicate the Sebel patent formulation, along with some compositions suggested by Dr James Taylor, using ammonium dichromate (NH4)2Cr2O7, an energetic oxidizer that happens to be toxic. I've never heard of a single successful flight with a Powermax Jet-X pellet. Edward
