I'm starting to gather parts for my Red Max upscale and I have a question. (Jim...if you're back). The rocket will have interchangeable motor mounts. One I'd like to use is the 3-24mm cluster in a BT70 tube. Fliskits has two options on this mount. I'd rather use the classic engine clips to hold in the motors so I'm interested in his EMK3-24-70 kit. The other style mount doesn't have the clips, and I'm not a fan of masking tape to hold engines in....too much hassle.
The question. In this mount the three 24 mm tubes mount inside a BT69 tube without any centering rings...then this all fits inside the BT70 tube that's the rocket's body. BUT...without any centering rings, the back end of the rocket is open between the 24mm tubes. Wouldn't this vent some of the ejection charge? Or is the ejection charge from 3 24mm's enough to still pop the nose cone? I suspect that it is...just wanted to see if anyone's used this cluster mount in a rocket yet.
Thanks,
John
