Crashed Mercury Engineering Integrator - Guidence needed

Well I crashed my Integrator over the weekend through stupidity on part. Anyways I removed approx. 6 inches off the top of
the body tube and have reordered a new nose cone. My question to you experienced Rocketeers is, can I just go ahead and load
this up and launch it again. I realize it has lost some weight and I can throttle down on a motor, but now that the center of gravity
has been effected, is this a dangerous machine to fly? or should I just get another one. It was one of my favorites.

Any assitance or suggestions are welcomed. I am new to this forum

Thanks

Kevin

Keep Calm and Launch On

A qualified "Yes".

The qualifications are:

1. You make sure that the CG is forward of the CP by at least 1 caliber (more toward 2 is better)
2. You weigh your rocket and simulate it with sim software (e.g., OpenRocket) to see if it can manage a safe flight (deployment near apogee)

I will take your advice

Thank you

RockSim shows 3+calibers of stability with F21 motors and 6 inches off the tube.

I will be working with open rocket...

Thanks for you assistance......

Time spent with openrocket is time well spent. With the relatively simple shape of the Integrator, I might consider going old school with the cardboard cutout method to find the CP:

Hey Thanks Samb...appears I will be going to school this week end,
you would think after building 40+ rockets I would know how to do this.
Until now I never needed to.

always good to learn...

Thanks

Kevin
until now. I guess we have to start some where.
