my first big rocket

[libyarocketry]

I use to build rocket motors mostly from 30 centemeter long aluminum tube by 7 centemeter dia. on rockets 120 centemeter long.
on practice test on flat land it makes 1000 meter distance within 2.5 seconds.
in my big rocket i fitted 3 motors of this type willing to make it fly 3 times the single rocket..... well i was rong on my calculation.
I don't know far it went or how fast it was.
sadly i don't have any electronic system to measure speed and altitude.
see my test http://rocketlibyan.blogspot.com

That rocket moved very quickly. Three times the propellant results in more than three times the speed and height as you found out.

Do you use parachutes or do your rockets crash?

i never use parachutes or electronic sensors for my rockets they all crash.
time took this rocket from start to crash is 20 second.
crash point was 1000 meter away from starting point .

i am trying to make hand made parashut and sensors.

I am not sure how easy it would be for you to get electronics from a vendor on these forums, but they make altimeters that deploy parachutes based on the altitude of the rocket. It seems a shame to crash a rocket on every launch.

i know it is not easy to buy and send to libya.
for the time being crashing is the only choice to continue rocket flying.
may be soon i will find solution for it.

Do your motors have delay grains?
