How quick is the burn on the Kno3 motor Quote ( the rocket is spending 9999% percent of its flight with the engine without fuel) .

When im usally designing rockets , counting of the size of the motor, i alway pick the biggest motor and then make the rocket with the motor loaded in the rocket, also ...

Hmmm. Have ever heard of a program called Rocksim , it can build rockets quite well its accurate but it is costly for the full version ($100), have ever thought of the CP - CG realations . But there is a 30 free trial demo.

This how the whole rocket stabillity thing works

now if got a simulator ...

Well i have a tennis ball launcher , it s combustion chamber is 100mm in dia and it it is a "T" section based chamber . the arm on the
"T"
^
the arrow above that is pointing to the arm im talking about, is 65mm long , the transtion is 5 cm, long and the barrel is 36 inches long and is 65mm ...

thats good that i have a converter. What if the gun has a 100mm "T" section , dose Burntlakes RatCal only do spud guns that don't that a "T" section as a combustion chamber

Here a link to what i mean by "T" section http://home.swiftdsl.com.au/~epht/cannon.JPG
