FW Eurofighter heavy nozzle

If tailweight is needed for CG positioning, each of these nozzles weighs between 30 and 50 grams depending on how you print it. Each nozzle also has slots for inserting lead shot or small weights, up to 50g per nozzle.

IMPORTANT: The duct through the nozzle is offset at the front by some 3mm to match the hole in the foam where it attaches. You will need to ensure that the nozzle is in the correct orientation for the nozzle to align with the hole. Just rotate it until the best fit with the hole is found, mark the position, then glue it to the stub.

The cutting guide slips over the foam stub where the stock nozzle would attach, and indicates where to cut so a 6mm foam stub is left to which the new nozzle will be glued. (Shortening the stub leaves more room for weights). I suggest marking the stub so you can correctly align the petals on the new nozzle, since the original alignment grooves will have been removed.

Make sure it is securely attached so it can't fall off in flight.

I suggest taping the join on the inside both to strengthen the joint and to smooth the airflow.
