Considering it's length, I doubt you will need any extra weight in the nose. But, that's just a guess on my part.

 

[Missileman]

Same here, with that length I would be very surprised if any noseweight is needed, In fact I would be willing to bet it is already over stable,

Ill rocksim it for you tomorow morning and give you projected altitudes ect, but you will have to PM me a few details. From what I figure , it wont need any nc weight.

Corpse,

Attached is a RockSim 5 file that should be close, since I dont have the details. You should expect an altitude around 1200 ft. AGL and you don't need any added nose weight.

I you want a better simulation file you need to post the details such as fin and nose cone measurements, launch lug location, and motor mount, parachute and other internal details.

Do you have a thrust curve file for the econojet F21-8w? I had to use a F24-7 which is similar..

I forgot to mention that the above is a RockSim version 5 file that can be opened with the demo version of the software.

nice looking rocket,
once you launch it, you'll want more power

 

[corpse]

thanks for the info.
only about 1200 feet. thats to low
maybe i'll stick that F in may Executioner
how high will that thing go ?

 

[teflonrocketry1]

I ran a few RockSim simulations; the Estes Executioner should reach about 1000 ft AGL on an F motor.

When one considers opening a video by two guys named....CORPSE and VICIOUS.... maybe one should CLEAR the room first....or wait till LATE AT NIGHT!!!! GOOD VIDEOS GUYS!!!! Your rockets ROCK and the camera work is EXCELLENT!!! How much damage do the rockets sustain coming in from those heights on streamers?

 

[corpse]
