I built a custom rocket, the first stage will be a D12-0 and second stage is E9. The rocket overall is about 34 inches and should go to the moon!!
My question is:
How close do you think the rocket motors have to be in order for the first stage to ignite the second?
Currently I have a thrust ring in between which is about 1/4 in thick. Do you think I will have a problem igniting the second stage with this gap?
I have heard you should tape them together or at least butt them up against. IN looking at the gap I couldn't imaging that a 1/4 gap would interfere with a mad fury of flames igniting the second stage?
I am launching tomorrow so any quick responses would be great
