Czx7 Posted Monday at 02:47 PM Posted Monday at 02:47 PM I am currently using 65 perchlorate, 35 kbenz, 8 perlite and 3 red gum formula from rockettests for my little 5/16 bottle rockets which works great. I have also been experimenting with the 1lb rockets as well. I noticed that rockettests also said that he said that the Kbenz could be swapped out for KHP. I know most of the KHP fuels are wicked fast and like to CATO. Is this formula the same with regards to the CATOs?
