Running a Tekin RS with a SpeedPassion V3.0 6.5t motor. Geared at 22/87t (48dp). Speedo set to Dual mode, 5 timing, profile C1 (which is identical to profile 3) current limit 40 and the motors physical timing fully retarded.
Im finding the speedo is almost at thermal. Run's fine at the start of a run but by around the 3 minutes it begins to cog as the speedo gets to hot. At points the speedo seems to freeze, then after a few seconds comes back to life.
I believe the RS can handle down to a 5.5 motor limit so ideally it should be able to handle this motor. Have I done something wrong here or set something incorrect though for it to get so hot ?
Any help would be appreciated. I do have an RSPro in my 2wd so may well swap this into the 4wd where im having this issue.
Cheers

It is rated down to a 5.5, but with all that current limit on a high current motor, the speedo is gonna be working hard to limit all that power.
It does this by basically turning on and off, thousands of times a second which is what generates the heat. I'd swap them over myself. Its almost like running on 1/3 to 1/2 throttle for 5 mins, so I'd expect it to get pretty hot. Guessing the motor is cool too?
Your best option though if you need to limit the speed so much is to put a more tame motor in there. Maybe a 10.5 would be more suitable.
