HELP ! MMP + Spektrum RX = cutting out ?

Well , its still cutting out just a tiny bit when you hit full throttle from a dead stop WITH the external BEC !

Tried going too an ACE 1015 servo also but that didnt help either

Man I was hoping not to have to buy another ESC but I dont like the way the MMP runs the Novak 550 motor

I was going too try a cap with the BEC next but I dont want too spend anymore money trying fixes too get this thing to run correctly
