Can anyone tell me if the Tamiya li-po chassis's carbon L type battery brackets can be adjusted not only side to side, but forward and back also? I was interested so as to adjust perfectly for differnt li-po's length so as to stop battery moving forward and back under hard braking and throtle.
I have not purchased it yet

the xray is slightly a bit expensive. talking how tough is the car? the xray tc fits the catagory. but u know a more harder n rigid car have it's con too.. besides tamiya tc are more frequent in podium as u may see... on reliability, durability & maintainance.. the tamiya trf cars competitive as xray tc.

so my choice is tamiya 416 series, as parts availability & support are far better than xray.. that depends which region u are in. so the tamiya tc wins..

Hi,
there appears to be two settings you can have it on eg: too battery lengths but dont quote me on that, I just have the chassis sitting in front of me

Default Very low grip asphalt base setup

Can anyone suggest a good starting point setup for very low grip outdoor asphalt on medium sized track. I just purchased the new Tamiya lipo upgrade and no matter what I do I have a real loose rear end. On the track with the kit setup slightly altered the car just has no grip in the rear on or off power. The rear end is just sledging around all over the place. Have checked all the settings and its got me baffled. Ive only own the car for a few months and have had little track time due to poor weather. Any help would be much appreciated.

Try wider front track, softer springs and shock oil , lower rear roll centre and some rear pro squat.

Hello,

This week, i ran my new freshly builted 416X with a Smokem 416FX chassis.
The car is perfectly balanced and weigth is equal left/right forward and backward.

All the stuff is new, tire glued and EPA is correctly setted.

And from the first time i put the car on the track, the 416 lose the rear left and right but left is much violent than the right but basicaly, no traction on the rear.

No tweak on the chassis and no pin bented.

The main problem is, the car dosent react to my setup change.

What i think is the smokem chassis is have too much flex.

Anybody have a similar issue ?

thanks

Please don't take this wrong way.... but have you also checked:

1. shocks (air in them, leaking, not equal rebound)
2. rear toe blocks are aligned properly
3. is droop set correctly

Also, are you running a gear diff? and what is the track grip like? are the tires properly glued to rim?

I have been running the Smokem FX chassis on low-med grip outdoor asphalt tracks with great success. Laptimes are definitely faster compared with Tamiya lipo chassis.

HTH.

I just bolted the smokem fx deck on, interested to see how it goes. It has a bit more flex than the standard deck, particularly at the front. Hope the weather stays nice

Thanks for your answer,

Well, shocks has been builded, no leak, no bubble and air in them.

Rear toe block are been aligned

And finally, droop are 6 front and 5 rear with 5mm front and 5,5mm rear ride height.

I inverted the tire and no difference.
Flipped the upper deck, no difference

Track had lower to medium grip.

On the begining of the qual, when the tire add is fresh, the rear stay a bit more on the track.

I tried to put the tire additive only on the rear first and 10m before the race, put in the front.

No change...

My springs are dark blue on front and yellow on rear. Oil i started with 45wt to all and put 55wt on rear to give a bit more rear traction on high speed turn.

I m need idea!!

But the big mistery is the car turn more on left than right !!

Put your tamyia steering brace back on the car with the screw in he top deck

And make sure you have equal throw left to right in your steering

You may have to much grip in the front end

Also try silver springs alround or go softer in the tamiya this worked for me on the weekend

Although I'm still have a touch to much I will try a one piece d block tomorrow

Xchange, are you running a gear diff? That can make quite a difference, especially if it is not nice and smooth or with the right oil. Also some people have found the gear diff difficult to drive on low traction surfaces.

Sometimes in my pit the car looks balanced...but at speed on the track it does not feel balanced. To fix this I usually adjust some weight on the lighter side. This assumes something bigger is not going on in the car. It sounds like you have checked most of the things that could be part of the problem. Make sure all of the shock lengths are the same...this could be causing your issue.

As for the problem about the car being loose...it sounds to me like your front tires are getting to hot. To fix this I would try a couple of things:

If you are on carpet I would run HB Silver or Tamiya white springs up from with 45wt oil. I would run HB or Tamiya blue in the rear with 40wt oil. 1.5mm over ride height droop both front and rear.

If you are running on pavement I would run HB silver with 40wt oil. In the rear I would run HB silver or blue with 40wt oil. 2.0mm over ride height droop both front and rear.

Although Yellow blue seems like a good combo...I have yet to find a track that this feels good on. I have spent a lot of time testing springs and I have found that the Hot Bodies springs feel the best on the car regardless of the surface, but some people swear by the Tamiya springs on carpet because that is what the team drivers run. Simply, I run what feels best on the car and I can tell you that HB springs are way more consistent.

The Key is to control balance in the car...I have not run the smokem chassis, but it sounds like with your suspension setup the car may be simply too soft.

good luck!
