Re: RXV or Precedent??
Kernal, sorry I posted that before I saw your response...that makes more sense! I have seen a lot of lifted rxvs on google-are they most likely using upgraded controllers, or just reprogramming?

Re: RXV or Precedent??
A stock controller is 235amp Curtis makes a 350amp controller to handle all the upgrades. Bob Boyce can program the 350amp controller for your needs.

Re: RXV or Precedent??
It's both, now and later. Now= poor braking performance, huge loss of hill climbing torque, strange characteristics when coming to complete stop. Later= failed controller.

Re: RXV or Precedent??
Gotcha-makes perfect sense. Thank you all for such great advise. I’ll look into the difference in doing it with or w/o the upgraded controller. I love the look of a lifted cart, but not at the expense of breaking my new cart!

The RXV is different than other golf carts in that there are no wheel brakes, the motor is AC (brushless) and the controller controls, well, everything. The motor is the brake. The controller is "mapped" for lack of a better word. When you use tires bigger than about 21" (some say 20-20.5") you are outside of the controllers mapping (again maybe not the best word) and the possibility arrises of overheating, corruption of the software etc. Braking will likely be reduced (the motor/controller) is the brake. Slow speed maneuverability is difficult because the controller becomes slow to respond. ( not technically correct but that is the seat of the pants feeling). Similar problems arise with regular DC carts. The stock drive train is designed to power the cart with 2 riders and clubs at speeds below 15 MPH on a golf course. When you add large tires, back seats, long canopies and extra bodies(people) you are exceeding the design parameters. So over time the controller and motors overheat and eventually fail but now you have exceeded the short if any warranty from the seller. There isn't any profit for them in drivetrain upgrades which are necessary for optimum performance and reliability. |

Re: RXV or Precedent??
So here is the part I would need, which is 1500-any downfall to using this navitas one for half the price?

Re: RXV or Precedent??
Take your time one will come up on eBay sooner or later. They go for around $800-$900 for the Curtis 350amp controllers. Like I said Bob Boyce can program it to your needs.

Re: RXV or Precedent??
I think that sounds like a winner-and I’m assuming that with the 350 amp controller, properly programmed/tuned you could put any size wheels and tires, lift, etc. that you would want...?

I got a 2016 specifically so I would not have pay to replace the controller. I just had to get Bob to do his voodoo magic on it and it was a completely different machine. Sent from my SM-G960U using Tapatalk |

Re: RXV or Precedent??
On my RXV I'm running 255/50-12 EXCEL Classic, 21" tall, with 2" front wheel spacers on the front without a lift kit. They run great but will still rub if I turn the wheel to the stops. Keeping the center of gravity low and the added width of about 4" really helps keep the cart more stable when running 20+ mph.
When these wear out, the next set of tires will probably be 20-20.5" to avoid the rubbing issue. Sent from my SM-G960U using Tapatalk |
