I've been running two since May with Xcelorin S 6.5T motor in my B4's and no problem so far. The fan on top of the ESC is too high for a standard B4 shell so I run the ESC without a fan attached and no overheating issues so far.

The quick program board is useful but unfortunately you can't change acceleration settings with it, so I generally program the ESC via my laptop which is a simple process. I also updated the ESC firmware and this was straightforward (I know others in the past have mentioened they had problems with upgrades).

Never run LRP/Speed Passion so can't compare.

Cheers Tony
