How far from a motor should a baffle be? I'm going to build a few BT-60 size rockets and thought the baffles would be a good idea.
I thought I read somewhere to have it at least 9" forward but can't remember where it was or why. I did think about the advantages of moving the CG and keeping the chute up top after deciding to install the baffle.
Good idea!Another tool I've been using on baffle plates is 2" stainless Steel foil tape on both surfaces UNDER the epoxy. This little addition has more then doubled the useful life of baffles in several of my smaller BT-50 models, which seem to burn through epoxy clad ply baffles in 15-25 flights, clustered models as well which seem to erode even quicker. Eventually these will fail as well, but the cost in time and material has been nothing compaired to adding live to the longevity of many of these models
