• High-quality spiral wound paper tube for larger rockets• Capable of handling our 29 mm model rocket engines• Make it’s possible to create a rocket that’s over 4 ft. tall
The BT-65 Body Tube is 23.5 in. in length and can be used to create a single main body tube rocket capable of handling our 29 mm E16 or F15 model rocket engines or by incorporating the included blow molded BT-65 nose cone and tube coupler into the design, it is possible to create a TARC winning rocket that is over 4 feet tall! To power this huge rocket, we’d recommend using our 29 mm to BT-65 Laser Cut Ring Set and related engine mounting components that should easily launch this rocket with an egg to the TARC competition requirement of 800 feet! This part is used in the Green Eggs and Olympus rockets.
I ordered these for 29mm rocket engines. It does not work as it is far larger than 29mm. The description does not give a measurement of the tube which would make it easier to find the right size tube. The description is misleading and I feel Estes should send a return label as the description was not clear on the website. I don't want to spend more for adjusters so am trying to send these back. Sending them back UPS is $55. The refund would be about $60 so it's not worth while. USPS is about $26 so that will cut my refund down but I cannot use these tubes.
The Spectacular Return of the ESTES BT-65. I still have 2 old fin cans from ESTES Challenger II 24mm motor booster for the ESTES 110 ASTROCAM and a few nose cones. The tubes that I have are 12 inches in length, so I will definitely order some of these longer body tubes and using less tube couplers is a must for TARC. Thank you, ESTES, for bringing back the most heavy-duty paper body tube on the market.
