Same here, if I can ever get the blooming thing to calibrate with my 3PK!!

Not sure what pinion mine came with, but I'm starting out with 2S and will see how it goes. I scored a like new one on Ebay that included an elect conversion as well. I will be using the RCM kit and the pinion from the other. I expect to buy a 3S as soon as I get all the kinks and bugs worked out.
