i recently sold my Welgard 100amp esc...i had only used it once for a quick bench test....but now the person i sold it to seems to be having trouble programming it....the proper programming procidured were followed, and it takes him to the different settings to be programmed, but there arent any beeps that allow you to select the perameters......and when he hooked it up to a 2 pole motor (where i had already had it previously set) it seems to only run the motor at half the rpm's it should be getting...he also tested the same motor on a different esc and its getting full power with the other esc...has anyone else had similar problems with this esc?
