Does anybody know if semroc body tubes, couplers, nosecones, etc., are compatible with Estes parts? For instance, in open rocket, it lists the O.D. of the Semroc BT-60 coupler as 1.63" and Estes at 1.6".
BT-20 and ST-7 are nearly compatible. ST-7 has the same ID but the tube is a little thicker IIRC.
