Maybe a little late or untimely to ask but, The 2650 and 3s sound like a great power combo for the 4X4 Slash.
I know you only got 60 seconds of driving time befor your meltdown but, any positive comments on performance ?
EDIT; Sorry, thought your were runnin' 3s. I reread and seen it was 4s.
I retired from RC, now life is all about guns and long range shooting.
