my cougar has the 81t spur, a 22/23 pinion, 7.5T SP motor, vortex R10 Pro speedo(as from box), not added or changed any setting on the esc, its smooth, fast, easy drive and no turbo unsettling to worry about, had 2 others drive it as is and loved the easy drive and smoothness......
i am old school and not a fan of turbo etc......
YET!
But the grearing and motor T is about right either way, but many seem to have a higher turn(8.5 to 10.5) and add timing and turbo etc..... I prefer lower T and pure grunt...........
just my 2p..............................
