a few weeks ago i calculated the stoichiometric ratios for KNO3 and sucrose
fuel and it comes out to KNO3: 70.9% and Sucrose: 29.1% and i did some burn
tests of 3 one inch long pieces and the average time was 5.03 seconds. can
anyone give me some numbers for burn rate of the 65:35 ratio. i want to see
if the stoichiometrically correct ratio gives better burn rates.

I just made a 20g 65:35 batch of KN and xylitol fuel using the
recrystallisation method and was amazed at how soft the fuel was at room
temperature. It had the hardness of probably a bit harder than gummy bears.
It wasnt pourable when melted but it was quite a lot softer and workable
than KNSU fuel.
PS. Some time this week ill be making an improvements video for my rocket
motor showing better methods of making the grain and steps to be added and
left out. Keep an eye out :)
Kind regards
