I'm not disappointed at all; I'd rather suspected that that was the case. The parts (especially the motor mount tube) are the correct size for use in FSI rockets (CORRECTION: the 21 mm OD tube should be usable, if cut shorter, as a coupler for the 21 mm ID FSI tubing). I'm more pleased to see that Quest is finally showing signs, however preliminary and tentative, of growth.
