Yes sir, 2007-2010 chassis only had one revision I believe and it was the hold in the bottom of the chassis for the clutch nut adjustment. The bolt pattern for the 2011 chassis is the same, it has revised cutouts for the chassis stiffeners for the 2011.

EURO 200mm note, has anyone else noticed that most of the top decks for the nt1 are cut?

For more flex= more steering

I got that, it was just interesting.

new paint for SRC Kruzer...

Nice paint job!

That would be thanks to Lucky of ShopUFO, hard to be disappointed with that. I think it's time for a revision next cycle.

I ran the same spur and pinion gears all season without any problems until the weekend of our annual big race. All of a sudden I'm stripping the 2nd gear spur left and right. I went through a total of 3 spur gears in two days. I qualed in P2 and in the Mains I stripped out another one. I was so frustrated that I haven't touched the car since. Before I go through the car, do you guys have any idea what's causing this? Thanks in advance.

Make sure the two speed shaft isn't worn(the actual shaft), check the carrier bearings, clutch bell bearings, 2nd gear(if it's worn sharp it will eat gears), make sure your chassis is straight, and the screws are all tight. Also make sure when you set the gear mesh you check second gear with first gear off the shaft so you can check each individually. I would guess it's bearings.

Does anyone knows the sense of the brace in front of the rear diff?
You can see it on one xray in the EC-A Gallery from last weekende at redrc.
I cant upload pics. right now :/

Thanks!

Also check the travel of your throttle servo. Make sure under WOT the servo is not pulling the motor.

If you ran the same spur and pinion all season, chances are you ran the same rear bulkheads too.

Change them, get new bearings for the bulkheads and the clutch bell. Also check the bearing in the 2nd speed housing.

If you are stripping 2nd gear all of the sudden, means one of this items has failed or is about to fail.

this one?


So the 2 spd shaft bearings dont bind under lateral load, and maybe to take away some of the rear flex for more steering/ unstick the rear end. I chopped up an old V1 topdeck to do something similar a couple months ago.

ahh, I always change the plastics so I forgot about that, nice catch! lol

Is there 2 length of NT1 side belts? I see on the Xray web, there has 390 and 396. Which one is for which version of NT1?

the short belt was from the original NT1 v1 belt. I still have a stash of them and they work fine. The 2009 spec changed the side belt from v1 4mm to 4.4mm wide and 390mm long. You should be fine if you use the max exhaust headers, with the v1 or v2 radio trays. Some of the novarossi headers with the fins on the exhaust flange can cause clearance issues.

Correction 2009 was the first belt change, the 2011 has the 396x 4.5 belt. They are all interchangeable but the 2011 is the most durable.
