I Know that roughly the stock Titans are about 1700kv, even though brushed motors aren't rated in kv thats roughly what they work out to be. With the stock gearing (68/19) and 4s lipo a stock E-maxx 3905 is geared to do aprox 25MPH. With a 1600kv motor and 68/20 gearing the speed should be about the same but it's no where close, I'm much closer to 30MPH which if I plug in a 2000kv motor it works out. When I had this motor on my RC8T I always thought I was way faster than what I was geared for and I tried putting in 2000kv then and the speeds I was coming up with seemed much closer to what I was actually doing. This just confirmed it.
I never calibrated the rpm sensor, at least I don't remember doing it, but it started at 0 and came back to zero in live mode
RC-Monster RC8T 1515 2.5D/MMM/5s RC-M 4500mah
SC10 MMPro 13.5T 2s NeuEnery 5000mah
RC18T Mamba 25/5400kv 2s lipo + 6s NiMh
