Re: air start cluster
I can almost assure the motors wont fire as desired. This is one of the largest problems regarding cluster motors.

How are the motors going to eject?

Hi Booster 11

Do you think it will be a problem to ignite the sustainer on a two stage rocket? Huh

Can you help me on that one!

(i think it was you who helped me with the recovery of my 38 special booster) Cheesy

Re: air start cluster
Booster,

Why a cluster? Why not one single large motor with a sustainer?

If you need the quick boost of 7 motors why not go big with sugar?
