Well I'm now also a member on the backorder list for the 36-60-2000.
Looking to get a more efficient motor than the 8xl I am currently running on 14 cells (nimh) in my 1/8 buggy.
Will be taking the step to lipo within the next year or so, haven't decided between 4s or 5s but it looks like the 2000 would work for either. Just have to gear appropriately.
