That is the consensus; other folks have recommended using D10 or D21 composite motors. One consideration (particularly since these motors can have a "flare after-burn effect" after ejection [at least in the re-loadable ones, I think]) that others have mentioned in the MPC Vostok [and Titan IIIC] thread (see: http://www.oldrocketforum.com/showt...74&page=1&pp=10 )--even if one has C5 black powder motors to use (C6s are under-powered for these models)--is that an internal lining in the inner "sleeve" body tube is needed to prevent the heat from soaking through and deforming the outer plastic body. Stage couplers glued inside the inner body tube have been suggested, and I suggested (but have never tried) gluing Nomex felt to the inside of the body tube.
