Send your rocket up on a pillar of fire!
The EMK5-124-413-70 Engine Mount Kit allows you to design or convert most any BT70 based model rocket for 5 engine cluster flights, making use of a unique central 24mm engine surrounded by four 13mm engines! All FlisKits engine mount kits come with highly detailed instructions and laser accurate, sturdy fiber centering rings to allow for easy construction, super strong mounts and long life.
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.
