I'm going to save the fin slot cut away pieces for a future build.
They might make some interesting tunnels or "runways".
It's a little hard to see in this picture, The slots at the top of the picture are right after cutting.
The slots at the bottom have been sanded smooth.
The instructions don't say to sand the slots edges down. (For that matter, the instructions don't say much at all!)
You should sand down the edges.
The root edges of the fins won't fit flush with the plastic edges in the way.
First, thanks for the great series on how to assemble this rocket! The Estes instructions are definitely lacking.
ReplyDeleteSecond, I just wanted to mention that one only has to sand down the ends of the fin slots to be level with the boat tail surface. The sides don't hold the fin away from surface because the fins aren't wider than the slots.
