I'm with BIll on this. Make it longer / change the KN ratio.

Sunny,
It's hard to say from the video (and being a little too lazy to go
simulate it myself) but from the video, the sound, and the burn time I
think you are a little bit short of developing the real thrust and pressure
you need to fly. The burn sounded like it was about 5 seconds, excluding
the build up and tail off, and for that size I would guess something less
than a 1 second burn.
Really, you need to measure the thrust and / or pressure to know what you
have.

Finally I have success with KNSU propellant with two grains in PVC. All
the dimensions are same as before. SugPro guys solved my problem with
inhibitors and so I could test this sweet success.
Now my greedy question is that, Is this motor able to take a 1kg rocket
at least 10m up? Also I noticed longer burntime compared to other dextrose,
sorbitol based motors. Propellant weight was something 190g with 2 grains.
Your help will be precious :)
