my thanks to all that contributed, a few questions .By MM you mean the TMM,s on the RCM catalog,right? and if so witch one ? Also as a less exspensive option would a Mamba monster or max function similarly? My troubles have not been ESC they have been all motors and for now money is in real short supply and all my other ESC,s are sensored and the medusa/NEU arent sensored so the medusa,s are in budget and either of the mambas are closer to budget than theTMM,s, but if they arent gonna work ill just have to shelf the .5 for a wile thanks again Doug Shelp
