Fantom Ion 17.5 Turn Brushless on 4s Lipo

[MetalMan]

Running 4s 3400mah, geared 26/88 in a Blitz (tranny ratio of 2.6:1). That's pretty much HPI's recommended gearing for a 17.5 on 2s The motor hit probably 160-170 the last time I ran it (in sensored mode with 2deg. of timing "boost"). Previously in Smart Sense mode it reached around 140-150, but of course had that cogging issue. These temps are determined by the touch of my hand, which has become pretty accurate over the years.
