Yes, It was here;


Particularly through the 'S' bend before the main straight. Bit difficult to see. As mentioned by others, it was generally under braking for the tighter turns.

This was the B final, not the best quality but you can just about see where I mean;

Reason being they are wondering if they can use a bodyshell cutout for a T3 12 on a T2 007

Cheers
The 007 posts are more forward not by much though. You would have to cut the wheel wells bigger to make it fit

just wondering if anybody else had this issue.
Hi, not sure if you got this resolved but I had this problem also, it was driving me nuts

Then I remembered back when I had the T2 009 forward motor conversion I needed part 302077 eccenter to get the belt to sit correctly. I fitted them to the T3 and it gave perfect tension for high and low position.

It could easily be two tenths with a change like that. There's been some very well informed recent posts here. Battery (weight) forward is really smooth, lots of on power steering, rearward gives more pendulum effect rotation, and forward bite. But is usually harder to drive. Depends on what suits you or the layout.

Yes the connector end is a lot lighter than the other end. If you open a pack and look the cells are pushed away from the bullets. The bullets are soldered onto the tabs of the cells. So if you look at the back side of the bullets (toward the middle of the pack) that is where the cells actually stop and the bullets are attached. The cells dont go any further toward the bullet end. It makes even a bigger difference in a 12th scale as they are the same way.

Its a tuning thing that PL and a few others use when they are looking for something smaller than a shock/spring/camber change.

OK, guess I need to do more testing to get the most out of my battery orientation. For me, other changes would have to be made to run my packs weight rearward (plugs forward) cause I don't like the feel of it.

Luckily when I rewired my ESC to take 4mm connectors last week (I've run Dean's for the last 4 years) I left enough slack so I could put the pack either way round, certainly glad I did now.

hi all,

i'm looking to upgrade my '11 to the 2012 spec, and have read through the commentary regarding the thinner flex chassis upgrades from xray, smokem', VBC etc.

typically i run on low-medium grip asphalt here in sydney.

before i go out and spend the coin,would the advice be to go straight to the 1.6 / 2mm flex option from xray or stick with the kit chassis? aside from a lack of turn-in (which apparently the 12 spec is an improvement on), the 11 spec goes ok so i would rather not spend the extra coin if i'm not going to be happy with the upgrade.

looking forward to your thoughts.

Since you mentioned the other brands, I'd advise against the VBC one. I have the T32F conversion on an '11 and prefer my standard '12 for low grip asphalt.

I am about two weeks away from commenting on the 2.0mm chassis with the 1.6 top plate.
Xray product.

As a disclaimer I have not yet run the 2mm chassis.....

I have found that running the 1.6mm top deck on my car has helped with performance very slightly over the standard top deck, this is on medium/low grip asphalt.
Some of the guys that have switched to the 2mm chassis have said the car is more predictable and easy to drive when combined with the standard 2mm top deck.

Any extra flex you create in the car with the chassis or top deck is going to reduce corner speed slightly as some of the energy is being absorbed through the flexing of the chassis instead of being passed through the suspension into the tyres.

Default Rear rollbar mount

Hi,

Has anyone experimented with using the inner or outer rear rollbar mount over the stock position? I have read the explanation in the manual but was wondering if anyone had a better explanation or personal experience?

I have my cars set different and one of the is all the way on the outside but I have yet to go through each post and drive the car. I guess I probably should.
