Regarding the front bumper issue... I had the same problem right off... the screw just never seemed to take.. but after converting it over to a SL and putting that lil baby bumper on and having the same issue with the normal screw... here's the "boom"...

Use your small hex driver and punch through the back of the hole and use a longer version of the same hex screw... magic for this guys problem...

I agree about the maintenance, Tekno trucks simply don't need any!! however, the front heavy design can suck on some layouts.. if you have one you know what I mean. that same drawback becomes an amazing benefit when you encounter a track that does NOT have the dreaded jump before sharp turn combo. That combo will have you pulling your hair out with the tekno - until you learn to compensate with throttle going up and leaving the jump.. but that can also hurt lap times. so yea, tekno kills with its amazing change of direction and front grip.. but....

From my own experience,I've found that the Tekno can be push much harder and staying consistence throughout the race than the other.(not bashing the other)
I agree you can push this truck hard but I've found recently that the more finesse I use the faster I'm going. Sometimes slow is fast

Agreed. That was frustrating me as well. While alot of the changes I made made it better I still struggled with it. Then I changed how I drove it. Used more finesse. Take the jumps a little slower and land smother and hard on the throttle through the turn. I no longer have that issue and my lap times dropped considerably.

This past weekend I was racing indoors for the first time with my sct410.3. I practiced quite a bit Fri. night and show up for the race Saturday to run my first qual and my front diff outdrive snapped. My buddy who is a Tekno team driver and only had his eb48.3 came to the rescue with the new outdrives that Tekno just put out not long ago. Part number is TKR5114XB. I was leery at first as to whether or not it would fit being that the outdrive is made for the EB/NB ET/NT cars. Well I put it in and it fit like a glove. My question is, will this hurt my truck in any way? Should I go ahead and replace the others with the new ones?

Any of y'all having issues whit the inside of the hub's stripping out from crashing?.. I've had it happen to both the front and the rear. There's only a little bit of plastic between those two bearings that keeps them separated..

Doesn't look like Tekno or anyone makes any aluminum hopups for these...

They had a problem with that on the SL's, haven't heard of that happening on the SCT. But the solution for the SL was shims behind the pins on the axle.

And I've turned my 410.3 into a SL. The spacer/shim thought was exactly what I was thinking it needs. Something just smaller than the outer ring of the 13mm bearing.
Do you know what those guys used? If I can prevent it in the others and possibly fix the old ones that'd be awesome...




And on another note... what are some of yall's diff fluid weights? They redid the track where I run and there are some tight turns (mostly 1:10th buggys there) and I have shat for on power steering... I was thinking of 3-7-3 and seeing what happens. This will be the first time I've worked with diff fluid for tuning. Also reading up on what camber and toe on the front do for increasing turning...

No, Contact [email protected] with what the problem is, Tell them you have the EB48SL, since it's no longer an SCT, and that you were told there were shims to prevent this from happening. Also might be a good time to take advantage of their 50% warranty for the parts you broke.

Ebuggy I run 7-7-5.....sct I run 10-10-7....SL...Somewhere in there.
