IMPORTANT: Anytime you are designing a cluster model or converting a model from single motor to
cluster motor use you need to verify the stability of your model before flight. Adding more motors to the
model increases the weight in the rear of the model moving the Center of Gravity (CG) further back and
may cause instability in your model. If you are converting a known stable model, the easiest method to
assure stability is to fully load the unmodified model for flight (motor installed, recovery device, etc) and
balance this model on your finger. This balance point is the CG of your model and you should mark this.
Then install the cluster engine mount and prep your model for flight again. You will note that the CG has
moved towards the back of the model. Add nose weight to the nose cone until you have moved the CG
back to its original point. If you are designing your own model you should make yourself aware of model
rocket stability and the relationships between the Center of Gravity and the Center of Pressure and how
to measure both.
