Any setups or new ideas emerging from the Euro's as yet?

From the pics, can see split rear deck, sliced top deck, one pic showed a 1 piece full length top deck (which allowed fewer screws around the motor area)

Anything else new?
There seems to be a trend of running heavier oil with a really laid over shock too, not only on the 416 but cyclones as well. Combined with the ultra flexy top decks, the cyclone had the entire centre section of the top deck split, with 1 pic even removing some of the ribbing in the arms.

Speaking of which does tamiya make the short reversible arm in a plastic material? rather than the composite?

Besercoe:

yup. tamiya does make a plastic material reversible arm. they came in the TB-03 kits. short arms in a flexy material.

btw... heavier oil.. you got any examples? i havent strayed far from 400wt Tamiya yellow oil.. so its something id like to try

Had a go with a 416 on tues, rear end was a little too bolted, but i think it was kit setup, oneway and i presume 3 dregrees toe?

Not bad at all though.......one phi prev sold!!
I had the same issue with the kit setup. My 416 was not able to keep up with my other TC, so I completely changed the setup. Now I'm just waiting to get the time to try it out...

I cant recall what car it was on but i saw 70 written on a set of shocks on a car.

Personally i have tried using thicker oil, 50 and 60 and it settles the car down a fair bit, I am thinking with the shitty tires they are making nowadays, like the sweeps, then you need to keep the car somewhat flatter through the corner, in order to keep pressure on all 4 tires, as they just dont have the grip of what we are used to with the older style tires.

The angled shocks, softer springs (HPI Silver seem very popular) and thicker oils should really boost up the side bite, as well as all the work that seems to be happening to soften up the chassis (split decks etc)

im gonna have to try this. im barely scratching the surface in terms of tuning the 416 to my liking... but ive gotten stiffer with my springs while maintaing the 3hole/Tamiya 400wt oil combo. i wonder if its the same effect as going heavy on the oil and lighter on the springs?

I'd be really suprised if they were running oils as hevy as 60 or 70... never even ran that on the 415. At a push, I would suggest that they would have run up to 50wt max, but given the traction at the euro's was pretty poo (from people I've spoken to anyway), I would have thought they would have stuck at the 400/450 mark.

With regards to shock tuning, I personally find it odd using the same weight oils despite using different spring rates... I would have always thought it would be better to run a slightly heavier oil in the front to match up with the stiffer spring. It's something I'm going to try again this weekend, as I still need to dial out a little initial steering... so I'll try that, along with some front kick-up to help with the bumpy track

As for Marc's top deck... it pretty much acheives the same as what Jilles has done, in freeing up the rear flex more. It's just a neater solution

Ed

Ed, I don't know what the guys ran at the Euros, but I know at the ETS final they were trying as high as 60.

Aye, I don;t know for sure either... just speculating really.
Viktors setup from the TITC has him running 60/50, and that was a very high grip track apparently.. whereas at the Reedy he was down at 40/40...
Just going with the info that the euro's track was quite low grip, would make sense to use a softer oil... hopefully I'll get hold of a setup sheet, as soon as Eirik comes back of his hols

Hello,

I was in Spain and Marc ended using 45/45 with HPI silver/silver and 3 hole piston.

My 416 turns like crazy on carpet, but on asphalt, it had a miserable push no matter what I tried.

all the 416s here are doing great on asphalt... whats the bite like at your local asphalt track? and what tires are you using?

premounted RP30s and Sorex 36Rs are the predominant tires at the two asphalt tracks i race at.
