Wonder how he was getting the 107 profile to work with only a 4 cell. I have tried it along with a few others here with the 1S and no luck.....must be just that little extra voltage bump from 3.7 to 4.8 that makes the difference. Although I just Won and TQ'd in a local event this past weekend with my XII with a 1S and V3 17.5 using the GT 2.0 LPF.
I used the 312a firmware and it worked really well.
Can"t wait for the new 2.1 to come out.....
