Tekno RC EB48.4 Thread
#1051
So I went back and looked at photos people have been posting of their cars and several people have all the braces in like myself. But a lot of the "vets" appear to have them removed on the mid and rear. So definitely going to pull it apart today to remove braces and replace diff fluid.

I would get this Tekno EB48.4 Bearing Kit and add 6 8x16x5 and 4 5x11x4 of either the NMD or the ceramics if you really want ceramic's, but the NMD's are pretty nice.
Those will give you better bearings for the center driveline. (Diffs and pinions in the diff housings)

I've said it before, and I'll say it again. Average joe's like you and I, cannot be chasing the pro's setups. Joe & Ryan like their cars on edge and borderline twitchy. That doesn't bode well for us.

And leave teh braces in. Unless your a very clean driver, your asking for trouble. Alot of guys default to that because they don't know chassis setup. And then some guys know chassis setup, and that was a change that worked for them. BTW, yes, center and rear braces are optional on SCT and Buggy. I run all braces on buggy and truggy. don't run rear brace on SCT.

Ok getting a little frustrated with my new 48.4. Only driven it a few times and honestly it's all over the place. I'm certain it's a setup issue and we have our first race with it this weekend.
Current setup is stock. Track is hot florida, hard pack red clay with dust on top. Went out about an hour ago to practice and the car is spinning out every corner. On the straight it wants to fishtail as well. It's like I have no traction in the loose stuff.
I think I need to start in the diffs. It jumps and lands just fine (unless it starts to fishtail up the jump). But it just doesn't want to have any traction in the corners.
Instead of 10/10/7...does anyone run similar track conditions? I am going to tear it down tomorrow. It ends up on it's roof more often than not and I'm getting frustrated with my new toy. My son kicks ass with the 22-4 but we just can't tame the 48.4.

Yeah correct tires. That is the first priority.
Rebuilt diffs using 7/7/5. Moved the rear wheelbase back to the max for stability.
Changed to shock oil and set the droop to the proper measurement. Do all you guys run the shock boots? I always took them off in my 8e 3.0.
No extra parts left on the table so that's a good sign
Now to see how it feels at the race tomorrow.

I don't know about you guys but after blowing off the car and dislodging the debris I always spray down all the moving joints/gears with a shot of silicone spray. I've heard not to spray an actual lube on the car so I use silicone spray as a protectant that actually keeps everything loose and moving freely.

Idk for me it attracts more dust then it prevents. Btw is it ok to reuse diff seals or should they be replaced every time you change diff oils?
