I used these to make my version of the Estes mean machine rocket. Heavy duty and fit perfect.

"BT-80 Body Tube Coupler Uses Other Than Joining BT-80's Together"
I have used the BT-80 Tube Coupler, not just for making a longer rocket, but to reinforce the engine bay area for cluster modifications in the BT-80. 3,or 4 24mm motor clustered mods. 7 18mm motors and a single 24mm motor for a sustainer will fit in a BT-80, although I would only squeeze 6 18mm motors around a 24mm motor for fin through tube wall mounting purposes, if you dare, for mid power model rocketry on a budget.


Due to small parts that could cause a choking hazard please kee away from children 3 years of age and younger.
