Brief:
I wanted to make it taller with a huge payload section.

Modifications:
Well I built it following the instructions carefully. Then I sliced the BT in half. The lower section stayed on the booster but the upper was shot so I replace it with a packing tube. This is where I got the extra height. I couldn't order a bulkhead coupler assembly so I just sliced the one off the nose cone (leave at least 1 inch on the nose cone. To secure the nose cone I use sheet metal screws. To secure the coupler piece I used CA and screws. These screws will be used later to attach my recovery harness that will situate the BT horizontal so the camera can take pictures of the ground.

Another modification was the plugs that the instructions tell you to make. I attached screw eyes to the plugs hammered them in epoxied them then attached the shock cord to the screw eyes. The shock cord is now equipped with swivels/quick releases

Construction:
Well it took a long time to finish it because my paint went bad a couple times and spider webbed. This is a paint problem not a manufacturer problem. I'm going to stencil on NOVAIR (my logo) on the BT.

Flight:
Maiden voyage July 24th under 2 Aerotech G40-7wl.

Summary:
I like it a lot. If I get around to launching it again it will be under 4 G80-10 with an estimated Alt with camera payload 5,000 feet

I learned a lot because it's my first midpower rocket
