The length of the BT-50 in the Nike-Ajax kit is 18". An unsuffixed BT designation in Estes instructions means the full uncut length available from Estes. That means 18" with the exception of the BT-30 (9"), the BT-70 (17.5"), the BT-80 (7.6"), and the BT-101 (16.5"). Further, the uncut length of the BT-40 was 13.75".
