RE: MPI switches
i have 8 planes rtf. all have the mpi switches. i like them because installation is neat without the seperate charge plug. i started switching to the led model early last year after seeing them advertised. the charge indicator gives confidence in your battery condition & as a bonus that warns you at a glance if you fail to turn your switch off. got all mine from rcjunky on ebay. search for him, he always has switches, ext. leads, y harnesses & such.
