Help me chose a brushless setup for my Losi XXX-T

[Serum]

If you are planning on a nice and rather fast ride;

the wanderer 8S with a 7020 controller would do fine in your application.

Or the MGM controller, they have got this built in lipo cut-off, which is needed to prevent the lipo's from being damaged.

With the 7020, you need to use an external LVC device (low voltage cutoff) and the MGM needs to be reprogrammed if you want to change from NIMH's to Lipo and visa versa. Thinking about it, perhaps the 7020 is the easiest.
