Launch Lug Install and Motor Mod's

​

The thought is the asymmetric drag from the launch lug will make the "Glider" bank to the left... ​

​

The C11-3 motor was modified by adding to masking tape Centering Rings on each end. Then some Bird Tape mylar was installed as a Streamer between the Centering Rings.​

 

Swing Test

Schwing! It passed!​​Rock solid stability, Open Rocket shows a Caliber of 0.631 and a Percentage of 8.62 using a C11-3 motor.​

Furshlugginer... A Scratch Build

 

Furshlugginer: - in Yiddish it means something that is old, battered, or junky.​

I chose this name because I really have no idea how this rocket will turn out, or what it's design will entail.​

​

I started out using the LEGO model of the USS Defiant, which has a center body and a couple of large nacelles as outriggers.​

 

 So lets started with a BT-80H body tube and a couple of BT-80H outriggers. These will be glued together and left to dry.​

 

 2026-07-21 Forming the BT-80H Sub Assy

I submerged the BT-80H Sub Assy for 5 minutes in cold water, then clamped it in a fixture to make the overall height 2". Clamped the sides to make the BT-80H Tube Fins rectangularish.​

​

I'll release the fixture tomorrow and check it out.​

 

2026-07-22 Tube Forming - 24 Hours Later

Released the BT-80H Tubes from the fixture and there was a small amount of spring back. So I soaked them in water again for 5 minutes and stuck them back into the fixture​
