Over the past weekend I headed down south to Tekno Headquarters in San Diego. 4 *Mostly full days of testing and practicing were on tap as well as a series race. Day one was was an indoor test session at SDRC. There we tested with our 1/8th E-buggies and SC trucks. We also got a couple packs on the E-buggy light car Tekno had built up. After a full day of practice 10am – 11pm we called it a successful day. The biggest surprise for me on the day was trying E-buggy light for the first time. This class is awesome! I hope to get one soon and start racing it. It’s so much fun and I hope it’s a class that can really catch on and do well.
SC and E-buggy testing at SDRC
Day two we headed north and east to Revelation for some practice for the Saturday race. I chose to run 3 classes, with primary focus being on the buggies. We did a number of set-up changes for the track from the previous tracks we had been to with the cars. Biggest thing we changed in the buggies was trying the overdrive out. We put in the truggy rear ring/pinion in the buggies and on this loose track it really helped the cars out. Seemed to help in the bumps and in cornering for the loose conditions.

Note that by doing the overdrive on a track with traction you will work your center diff WAY harder than normal. If your diff was quite hot, it is possible that simple heat and use brought up internal pressure. Also, make sure you always use a fresh blue seal, even if you reuse the rest.

Around my area here on the East I haven't found a track I consider high bite. At best we have some tracks that develop a strong groove in certain areas but most of the time its med bit at best. I tested a team managers EB out last week indoors and for 80% of the track it felt no different than mine....but the 20% where my kit struggles, his car handled with ease. Much better on power, could hold tighter lines without the worry of the back coming around.

did you happen to get his setup by chance?

Anyone with the new locking perches having issues with them breaking?
I have them in two buggies and one truggy. All of the front ones are surprisingly, broken.
Also, anyone having issues with center diff leaking? I have been to the track three times with my buggy, and it has leaked twice now. All other diffs (even on our two other cars) have not leaked at all. I replaced diff shims (black), o-ring, gasket, and used grease between the case and spur. I also made sure to cross-tight the screws. Still leaks.
The first time, it was filled as per manual, second time a little less. Still leaks.

I have never had a diff leak, the way I do them is some may not approve, I just put diff oil on the orings, put it together, gasket dry, and both mating surfaces bone dry, and just make sure their tight, keep going in a x pattern over and over till they all feel the same and wont turn anymore, with a hand driver. And I fill them just over the gears pretty full.

It would be better for you to ask in the sct410 thread, as this is the eb48 thread.
That being said, check http://www.petitrc.com/setup/tekno/S...knoSCT410.html

The truggy pinion is 1T smaller ... so the front of the car was overdriven vs the rear?

For those that are thinking of trying the truggy gears in the rear, here's a couple of tips/things to be aware of -
-You'll need to go up 1 tooth on your pinion gear or you'll lose a noticeable amount of top speed.
-You may want to strongly consider going up in your center diff oil if you're running 5k or less.
-Be aware that your buggy will jump with more of a "nose up attitude" then before. Actually pretty useful for the SC.
-Your buggy will now have a slight drag brake off-power coming from the rear end.
