Not sure of the expected weight increase, but still considerably lighter than stock. If youre interested in the added strength of a 5mm tower let me know. I have Bruce from Xtreme lined op to start cutting once I get a number of how many are needed at this time.

I broke two .2 rear cases too at PNB this weekend, the only thing that stopped it was putting the rear brace back in. The track was awesomely difficult, but a little much for the eb48.2 I think. I broke a front arm in the main but i haven't check the rear case yet.

as this an older case? I thought this was resolved a couple months back

I have noooo idea. How can i tell? I bought the first one from a hobby store and the second one I got from Tekno themselves.

Also any have a set up for PNB they would be willing to share. My car felt good, But i think it could be better. Thanks.

+1 good list.

I would think the first one was definitely old batch. The second one you got from TEKNO if it was more than 2 months ago may have also been part of the bad batch.
I am not sure if they modified anything so you would be able to tell it is a newer version other than email TEKNO and let them know when you purchased from them.
Personally I am running EB48.1 and have never had an issue and have been reluctant to upgrade to .2

I put mine through hell there and didn't break anything. However, I was running the old non-angled case. The car could definitely handle the abuse. The cases that suffered from that bad injection process can't though.

So, are new cases ordered from the tekno site stronger now?

I might order some just to replace mine as a precaution. I broke one a while back but the replacement has been good so far. But if there was a durability improvement made I will probably just replace with the new and keep the old as a spare.

EDIT: Forget it I guess. They are showing out of stock on the tekno store.

The cases on the Tekno site are all injected properly and part of the good batch. We discarded the cases from the bad batch. Most of our dealers have them now as well. Unfortunately, it's nearly impossible to determine what is a from a good batch and what is from a bad batch without breaking it to find out.

We tested good and bad side by side and the temperature issue was definitely the problem. One small hit from the hammer and the bad batch broke. To break the good batch, you had to pound and pound on it.

Once the good batch filters through (there shouldn't be many of the bad batch left in circulation) we are confident this won't be an issue anymore. Thanks.

The hammer test seems to be the prudent way to go for anyone unsure of what they are currently running. Can you elaborate on how you did the test? Just clamp it to a bench and give it a whack?

Ok I just heard back from Bruce @Xtreme. The 5MM CF rear tower for the SCT/EB/NB would be right around $30. Let me now if you want one, and I can setup to buy a run of these.

Cheers Thanks for the clarification!!

How do I order these new gearboxes? Your site says you are out of stock. I bought my 48.2 and my et48 at the time of the bad batches. I would like to get these swapped out asap so I don't have to worry about it.

IMO you should not have to re purchase a new one if you have had a bad one break. Since Tekno knows there was a probllem they should just replace it if you send it back to them.
Just my .02 worth...

Understood, but due to the timing I'm in the block of highly likely to be bad versions and they wont simply replace known issues parts even w/ receipts and kit details. I have to break my part first, then have to not be able to race while I pay to ship them a bad part and wait for it to be shipped back and yes I have to pay to have it shipped to me as well. It doesn't cost me much more to just buy the good parts, and then I have piece of mind and I don't have to miss run time.

I've come to terms with what to expect for customer service w/ Tekno. My brand new Tekno ET48 has outdrives that show more wear after a few hours of use (visible cups) than my losi parts did after a full year of racing. The best Tekno would do is make me rip my vehicle apart, leaving me w/o a vehicle, pay to ship them the defective (new) part, then they will give me a 50% credit for more new parts to replace the defective new parts and yes I also get to pay them to ship me my parts as well. Good stuff.
