Tamiya Vega set-up
Here is the set-up me and Alec Springer are running on the Tamiya Vega at EPR.
Front Stagger ribs, normal ones with no insert, wheel cut down. Shocks -3 piston, blue spring for alec, kit spring for me, 30 weight losi oil 2nd outer on tower, middle wishbone. 4 mill under out ball stud on steering turnbuckle. Inner side front hole on the drag link. Camber turnbuckle, inner on hub, inner on tower with 2 mill under ball stud hub in middle, spacer either side of the hub. Rear Yellow mini spikes with Mr O foams. Shocks -4 piston, yellow spring for alec kit spring for me, 25 losi oil middle on shock tower inner on wishbone 0.5 hubs on my car, 0 deg hubs for alec. Long wheel base. Link, outer on hub with 3 mill under ball stud. we played around with the inner ball stud, i ended up on the upper 2nd inner hole. 3 deg toe in brace 1 mill shim under the front brace I have a speed passion speedo, speed passion 6.5 motor on kit spur(79) and 23 tooth pinion. The car was very good today. It was my fourth meeting with the car, but the first time with the car right, I had the servo saver waaaaaaay to loose and the car was doing very random things, locked that up and the car was sweet!!! I ran a used set of tyres in practice and put a new set of rears on for Q-1 and kept the same set on all day, I wanted to see how the car worked at the end of the day with worn tyres. There was a big drop off in performance in my final with shagged tyres. For big meetings I will make sure a good tyre is on at all times. I also rebuilt the diff last week with Lazy balls from R/C lazy with NUCLEAR R/C grease and the diff is probably the best diff I have ever built! And for those of you that know me this is an amazing fact hunt haha Both Alec and Myself will continue to develop the setup all this year and we both will regularly update our set-up in this section. |
Must say the car looked very good yesterday Dave.
Mike:thumbsup: |
Thanks for the set up but I have a few questions.
See red Cheers Quote:

Happy to share set-up info.
Answers. 1.3 pistons, well this is what the manual says, I run them as kit standard, Alec has drilled his with a 1.3 drill bit. Same for the 1.4 pistons, I use mine as kit standard and Alec drilled his with a 1.4 drill bit. Yes Tamiya springs. On the front shock tower say 1 to 4, 1 being closest to the middle and 4 being the furthest away from the middle we are on #3 Im either on red or yellow rear springs, I didnt build my car cause Im lazy and the colour has worn off the spring, but what ever was in the kit is on the car. yes starting from the inside on the rear turnbuckle ball stud. The toe in block is the right way up. Ride height is wishbones level front and rear. |
Cheers for the info.
Are you running the 92gr plate under the esc and 28gr under the servo? Thanks |
I only have 20 grams behind the servo, no other weight in my car, I'm not sure what Alec has on his, but I'm sure he will he will say when he see's this thread.

Got lots of weight in my car at the moment - mmm time to experiment. Got the rudebits weight under the servo, ESC and lipo at present! |
Talked about this with Kev Lee and he said that the car is more stable and planted with the weight in.
The weight distribution would also be much better. Something to test maybe? :thumbsup: |
Remember Kevin runs a 'Kyosho' Vega and in his car he runs 90g under the speedo more or less everywhere. He uses the under servo 28g and under Lipo weights where he sees fit as a tuning aid/balance of the car. - Hope this helps you guys.
|
As this is the same chassis and the weight distribution "should" be the same I was thinking the same weights are used or am I missing something?
What lipo's is Kev using and what lipo weight is he using on dry and wet medium high grip astro? Thanks! Quote:

I have tested various weights and as Tony said i generally stick to 90g under the speedo only. As i mentioned in the RB5 setup thread, if it's wet/slippy i'd take that weight out. Its still early days though... I'm using ORCA 5400 45C saddles... not sure on the weight though sorry Kev |

WHat cells are you running?
Thanks Quote:

Muchmore Impact 5000 35c

What spacers are you guys running on the rear shocks on the tower, on pictures it looks like the rear shocks are vertical, but having built mine even with no spacers they are leaned back at the the top, no badly though, probably at a similar angle to the anti squat?
Also, wheelbase, on the rear inner hingepin I only have 0.3mm play, very little and much less than Tamiya kit, are you guys finding the same (that wheelbase needs adjusting on the outers?)? I am using Ali front and rear suspension blocks on the back by the way... |
I've put a 2mm washer on the arm and it's perfect like this.

Maybe we are talking about something else?
I've put a 2mm washer between the shock eye and the rear arm and I have no washers on the tower (I'm using the option alu bit) |
Hmmm, thinking about it, this all links together...my driveshafts are angled forward, and my shocks too, it's like my rear wishbones are too far forward!??
A 2mm spacer on the inner hingepins in front of the rear wishbones would fix all this, except I can't fit one in as the space between my front/rear suspension mounts is too short! What could I have got wrong here? What way up are you all running the rear mount, right way up or upside down? Your all running the wish ones wrong way round like in the pics yeah, swept forward so with the "R" wishbone on the left and vice versa?? |

I have pictures of the car in another thread so maybe you can see what I mean?
|
WHat is the minimum weight in the UK?
I'm asking because when I take all the weight out like you guys said I'm at 1476gr. Cheers |

On the wheelbase i've dremelled away the rear raised section of the wishbone and inserted a TRF blue 2mm spacer at the front of the wishbone to effectively lengthen the wheelbase. I also found that dremelling the hub end of the wishbone (evenly) gives enough space to insert a 1mm plastic spacer so you can space it back and forward as necessary. If this isn't clear come and have a look on Friday and it only takes a couple of minutes to sort. :thumbsup: |
On the subject of weight, i'm going to try some stuff out tonight (Moto Arena) and will post on here tomorrow what the differences were :thumbsup:
|
Will investigate the dremelling to increase the wheelbase :thumbsup:
Where is the best place for wheel base adjustments these days, on the hubs or wishbones. I.e. inboard or out? |

DC, what do you mean when you say cut down front wheels, I've never run staggers before?? Are you glueing them??
|
Quote:
The inside of the wheel, cut to the first inner rib, leave the rib on, you cut off 10m or so, so the tyre sits narrow on the wheel. If you don't cut the wheel it makes the profile of the stagger rib much wider, then glue the tyre with none other than Nuclear RC tyre glue, it's the BOLLOCKS:thumbsup: |
we'll sort that friday if you nervous doing it mate:thumbsup:
|
Have you tried the cut staggered tyres yet?
|
Quote:
I've not tried them, normal staggers work just fine. |

Will 501 wishbones be ok on the rear as I broke the car testing :(
|
Mikey, 501 will fit but you'll need a dremel, as they foul on the outdrives as standard (the new dn01 wishbones don't).
Guys, setup wise, liked mine at Stot at the weekend, one thing though, feels like it could use a bit more droop, are you all using standard 201 shock shafts, standard vega tower etc, or have you tried increasing rear droop? |
How were the cars at Stotfold?
