I just wanted to come on here and say I'm so glad this community exists and was a big help in setting up my board. I have an original OneWheel Pint with a quart battery and ubox 100 controller. I knew it would be better but I'm amazed at how much more torque my VESC'ed Pint has than my GT!! The Pint now kills my stock GT at hill climbs.
The GT still feel more stable (especially at higher speeds) since its bigger of course, but I think the the Pint is my new choice for tricks and small jumps when just cruising around a park or parking lot. GT is now my long distance ride and dirt trail board.
The process of converting my Pint to VESC has been fun. :)
