Ed,

My 415 MRE is collecting dust, what's a reasonable price to charge for it ?

Thanks
Andy

Also, has anyone used the 416/TB03D aluminum rear uprights? Is it anything more than some more unsprung weight in reality?
The TB03 hubs are 1 for starters... so thats a big diff

straighter links, in my experience, give more steering feel further into the travel. The more angled link makes the car more reactive round the centre of travel.

Meaning travel of the suspension or travel through the turning radius?

He means the turning radius with respect to the wheel angle.
The angle of the steerling linkages affects the ackermin.
More ackermin makes the inner wheel turn more when its on the inside of the turn. For instance in a left turn at full lock , the left front tire actually rotates (yaw) further than the right one. The difference of inclination from right to left is the absolute angle of ackermin. More angle makes the car pivot harder through the middle of the corner. Less on the other hand will work better on sweeping turn tracks. Compromise is warented on most tracks.

Let me just confirm what your definition is as I always get confused:
More Ackermann - more angled links
Less Ackermann - straighter links

I don't understand why Tamiya chooses not to support there customers with setups for there top of the line car the 416WE.

Most all other manufactures like Xray, Associated, Kyosho, Hot Bodies etc, all support there customers with multiple setups from many different races!

It sure would be nice if Tamiya would release more of Marc Rheinard's setups especially the last Ifmar World Championship! In addition, it would be great to see the top three Tamiya racers setups that swept that European series carpet race, including that 16 year old kid Pumpler (sorry spelling?) that won the race!

hehe, I try my best to get some of the setups, in fact I have this years DHI one sitting on my desktop that I need to upload.

Thing is, in all honesty, not a lot changes geometry wise on the cars at the big meetings...but stuff like shock position, camber link shims etc can generally be easily picked up off the photos.
Most difficult thing is figuring out what's being run in the shocks...

Believe me, I wish there was more reporting on the setups too, but have to make do with the hand we're dealt, after all the TRF side is microscopic compared to the rest of what Tamiya does, unlike HB, Xray etc.

It's definitely got me looking more closely at the new TOP car. Proper support with a strong US team is compelling, I'm not gonna lie.

Try Hard, you are the Man!
You contribute a great deal of knowledge to our hobby! Thank you.

I felt it was important to write my last post, because i believe this forum is one of the best ways to effectively communicate with the manufacture.

Unfortunately, Tamiya may continue to ignore their customers request for these types of setups, but it's a least worth a try.

Chris, man what are you b!tching about? just kidding. you know ive tried the setups from TRF... they work.. but i feel they are more of just a starting point.

esp. since their track conditions very GREATLY from ours (big races usually almost always has high bite with controlled tires), it would be benefit tamiya drivers like us if changes were explained.... like how RedRC reports that certain drivers will do "A" to get more steering.. or go back to change "B" to reduce oversteer. etc.

be honest... none of us will ever drive like Rheinard.. so their set up won't really work for us. Plus the fact that i only race 17.5/13.5. I'm sure their 2.5 set up might not work as well as coming up with your own.

just a thought...

Default Kiyo....

what i would love to have is to have Kiyo Suzuki get on here..and explain some of the changes he does for Marc's car when Marc requests certain things... like if his car pushes mid corner.. or needs more entry steering.

that way we'll know what TRF's top mechanic does to get TRF drivers dialed in.

I wouldnt be so sure that their setups dont work, like Ed said, geometry wise the 416 setups barely change from track to track, surface to surface or tyre to tyre. I stuck a very similar setup to what Marc R ran at the worlds and ran it on a tight low grip asphalt track over the weekend and it was great. He was probably using thicker shock ail and all that but it worked nonetheless

I know Jilles used to pop his head up on here every now and then and they were trying to get the TRF america site to take off with setups but there just doesnt seem to be the same committment that other companies have to support. Lucky we've got each other

To get more steering in tighter tracks, play with your ackermann. Go for more angled steering links. Once you get close on that, then you can play with other things. Sometimes, if you don't play with ackermann, then no matter what you do to try and get more steering (or less), it will just not work. You'll be dumb founded on what to do with the car. So my opinion is to set that first, then just fine tune everything thing else. This technique has brought me the most success with the car, especially since I ran in all kinds of conditions and new/different tracks.

More angled links = Less Ackermann = tighter tracks/more steering = more off power steering.
More straight links = More Ackermann = flowing tracks/less steering = more on power steering.

Chris,
I know your a little biased in your response because you've been such a looooooong time, die hard, Tamiya fan, that refuses to think Tamiya can do no wrong. Over the years I've owned many Touring cars, but this is my first Tamiya! I had high hopes because I just spent well over $500 of my hard earned money in the middle of a freaking Recession!

My first impression of the car was great, I really love the design! Although, After I started to develop problems with the spool cups and wasn't able(and still unable) to purchase any replacements I was little unhappy. Now I find out that Tamiya does not care to support their Customers with setups of their Top of the line 416WE.

By the way, i have been around long enough to know that the best setups are found on your own, but since i can't live at the track like a lot of you guys, it would be nice to have some support from the manufacture for some guidance.

I think what shocks me the most is, I assumed that Tamiya would be working harder than ever to make their customers happy especially in the middle of one of the worst economic crisis's ever!

P.S. if my B!tching works then everybody wins. Happier Customers=Tamiya makes more MONEY!!!!!yay
