Your 66/13 and 2nd gear gives you about a 9 to 1 gearing ratio. the 56/10 slipper/pinion would give you a 5.6 to 1..
Stock diffs are 37/13 and the HB diffs are 43/10, meaning your total gearingratio now would be something like 25 to 1 .With the slipper (56/10) with HB diffs would give you an 24 to 1
with stock diffs and the slipper, that would be like 16 to 1.
My word of advice; if you want awesome runtime and speed from your hv-maxx get a 4S lipo setup! you'll love it.

hey serum dude..thanks for doing the figures for me...its the numbers thing that scares me all the time...so i always do the "slap it on and see if it smokes" method of finding gear ratios...haha. thanks for saving me the hassle and sleepless nights.
lipos?? i wish dude, but current state i'm in, i'm lucky i dun have to sell of my RCs.......

Plus 10 51 meant that there weren't enough teeth in contact, the 10 pinion was too small a gear with this power, it would rip the teeth off the spur. so 12/56 gave a better contact patch between the gears. Ideal would be something like 14/65 but the spur would be too massive to fit in.

wow! never thought of "contact patch" that you mentioned!! imagine ripping the teeth of the spur!! yikes!!!!
so i guess all this brings me to this.....
since ...
i wont be buying a new BL system...(anytime soon that is)
and
i dun wanna butcher my nice Gmaxx chassis....
me thinks me leave the emaxx tranny in there for now and use the dom slipper for another project!!!!
thanks guys! many thanks for clearing up my Qs....
