My favorite kit ever! I followed the instructions which were well written and illustrated. The only thing I did different was I painted as I went as I completed sub assemblies. I left out 5 plugs which ensures chutes are deployed and allows more cluster configurations. I have flown mine about 10 times from 3 engine to 5 engine clusters. It flies straight and true, the smoke, flames and roar really give a crowd pleasing flight! Excellent parts and quality service from erockets and semroc as always!

Excellent rocket!
Very good rocket kit, and I highly recommend building it! It's a little bit difficult at some points, but overall is a very fun kit to build and fly!

A unique low-power cluster rocket kit
These are my initial impressions, as I haven't built the kit yet. This is a very unique and challenging kit! I'd recommend the builder have experience building 2 or 3 motor cluster kits before taking on the challenge of this kit. The components are all high quality. The instructions appear to be through and full of details. Only normal building skills are needed, but the builder must follow the instructions carefully. This is due to the high component count in the kit and the way they all fit together. Launching a 7-motor cluster isn't trivial either, so prior experience with launching cluster models is needed. It is designed to fly as a single motor model, or as a 3-motor or 7-motor cluster model. I plan to try to hack the kit to also allow it to also fly as a 4-motor cluster.
