As this is my 3rd Starlight build Im not sure if the instructions are getting better or Im just getting used to them. Again the drawings need some help but do help with the assembly. Unlike the other two Starlight kits Ive built this one had an optional instruction to help the rocket fly higher. All in all the instructions are good and easy to follow. As for parts I only had one problem. The engine block was very loose inside the body tube. I had to use a long piece of spare balsa to get more glue on the connection of the body tube and engine block. This kit also came with an engine spacer dowel for easy placement of the engine block. I also noticed that the balsa in this kit was a much better grade then the last two Starlight kits Ive done. The recovery system uses a mylar streamer but the attachment system they use could use some work. The paper tape disk is very thin and rips easy. I also dont like the attachment of the shock cord to the body tube.
