Hi everyone! I have been following this thread and had My eb48 for about one month and am very happy with it. I drive on a tight track in gothenburg, Sweden (1:10 track actually) and i really epreciate the nimble feel of the car.

It has proven to be quite durable and the rear(?) shock shafts and guide collars are the only things that have given in so far. Since the collars are backorder on amainhobbies I put a piece of brass in the lathe and made some new. These should last!

i'm still not fully satisfied after these speed runs although it shifted out of the course towers some hard terrain and i lost the front right steering arm's nut and screw but i manged to repair it buy getting some identical screws and nuts form my other rc cars spare parts ( rustler's screw & a nut from the tools shop ).
here's my setup i currently ran with :


venom 6S 35C 5000 mah
26t pinion / 44t spur
hpi Tork flux 2200 kv motor and blur esc cooled by frozen blue gel
proline badlands tires as the slick, foam tires won't hold on the asphalt here
hitech ultra torque servo
futaba 3PL radio
Another thing to try for high speed stability is to run heavier diff fluids. Something like 30k front, 50k center, and 20k rear. This will lock in the car, and prevent side to side oscillation at speed. I would also balance the tires too.
Going fast is always more difficult that you first think. In full size racing the saying is - Speed costs!

Nice work! Just watch the wear on the shock shafts.

The motor was only in the 170°F range which made this seem even stranger, I'll rebuild the center diff based on these findings, however I wonder what normal Diff temps should be? beside the high temp reading everything else appeared to be good - no sign of a leak, diff seemed to be smooth and the car was hooked up after I changed from 4.5° rear toe in to to 5° of rear toe-in. I'm guessing the drop or two of the 30k fluid might be the reason for the high center diff temp but, I'm not sure why. Appreciate any insight to this or what to avoid doing in the future.
If the diff temp is high, it is because the diff is unloading too much. The switch to 10k was correct, but 15k might be called for. I'm using this in my buggy on loose outdoor tracks with success. The other solution is to have a more gentle trigger finger. Stabbing the throttle will absolutely cook the diff fluid

Thanks, I will! If it wears to much Ill switch back to the plastic ones or lathe some delrin or teflon ones. Brass should have some selflubricating capabilities though. Ill keep you posted!

Any idea what an ideal Diff temp ceiling should be? this also makes me wonder how warm my front and rear diffs are running.

I do have a tendency to stab the throttle, looks like I'll need to work on that as well...

I've noticed mine are pretty hot as well (both SCT410 and EB48) but to be honest I haven't temp'd them yet. My center diff on my EB48 also leaks slightly, so I have to get that sorted out. I'm running both metal diff mounts, which I believe helps dissipate the heat at least a bit.

I actually stacked two gaskets and used longer screws to attach the spur gear on my center diff which stopped any leaking I had. Things got too tight in the diff when I used the longer screws so I added an extra gasket and it freed things up and has worked well for the last couple of fluid changes.

I am waiting on my eb48 with tekin esc, 1900kv motor and savox servo. I see most of the setups on tekno's site are using a 2050kv motor. Is 1900kv good setup with 17/18 pinion on an outdoor rough and technical track? What recommended upgrades do you suggest?

I have the hobbywing SCT pro, Tekin 1900kv and use a 16 tooth pinion on this track. http://www.bgrcr.com/ works great. Could probably get away with a 15.

I have the 1900 Tekin, SCT-Pro and run an 18T pinion. I ran 16T and think I was getting a bit too much heat with the motor spinning pretty hard. 18T seems to run cooler for me outdoor.

I'm running the Tekin RX8 with a 1900kv motor-16T pinion (indoor) and couldn't be happier. An aluminum servo horn is really the only must have upgrade, I've found the 1.5 rear hinge pin brace made a difference locking in the rear for my driving style and there is always the light weight option parts if you wanna deck it out.
