Been having alot of heating issues lately with the Motor. Pulled down the drive train and found the spur gear was slightly rubbing on the rear diff mount. Worked out that with the RCPD Mount it is best to mount the rear RCPD mount, put the front losi plastic front one on but not tighten and then put the top plate on as the top plate pushes the front mount 1 - 2mm fowards which is enough to stop the spur from rubbing. After top plate is on then tighten the front diff mount on the bottom of the chassis. I am also running a aluminum front bearing adaptor but can't see why that would cause overheating. When I rebuilt the centre diff there was a shim in between the front sun gear and diff case but didn't mention nothing about it in the Losi manual so I never put it back in. Motor temps were around 190F (even with the 11T pinion when usually run the 13T pinion). I put the shim back in and changed the diff fluid from 7-10-3 to 5-7-3 to see how that goes as that is similar to what the 8IGHT-E runs. Took it to the track today and temps were back at 165F (motor) but I didn't like the change in diff fluids. I changed the centre diff fluid back to 10 000wt but wont get a chance to run it till tomorrow. Hopefully temps stay down and might try out the 12T pinion.
