For me its a bit too low a speed from what I measure on the radar. To get the approx speed close I have to raise the voltage drop to very low levels (too high V under load really) or make obscene amt of ballooning.
Maybe its more on than it seems, but w/o knowing what the real #s are I'm just making reasonable guesses and getting low answers.
Eg: for my 5S setup, I was getting 48 mph reliably, 49 even a couple times, but the values below give me 47mph.
16/51 gear, emaxx 2nd gear, Revo diffs, 5cells@ 3.2V, 8.25" tires (w/ ballooning, these are the stock talons.)
These values get it close, but IDK if the tires get that big, or if the lipos hold higher V. They are a 8Ah 10C 5s pack from TrueRc. Maybe I'm just discounting the batts too much given the C rating, but IDK... don't have an eagletree.
This is pretty good tho, when I was using NIMH packs it was not so close.
