I used this product to build a Nike Ajax Air defense missile (Which was the predecessor too) and a Nike Hercules Air defense Missile . Bothe where my first design and Build Rockets! I dealt with the latter Missile system in the ARMY (Replaced by the Patriot Missile).Product is what I needed For Bothe Builds Along with other products

This is a great size tube that I like to use on many of my custom rockets. Its a good size and you can go with a C or D engine. Larger tubes allow for good siting - not to concerned with it getting beyond what I am able to track. Good and sturdy - not much more to it.

Was able to replace a damaged item on my Long Tom with one of the BT-50 tubes received. The new tube appeared stronger than the original. Highly recommend this product from Hobbylinc. Their shipment was quickly received from the time it was ordered.
