He wasn't saying all the tires should have the same diameter.
Just make sure that both left and right tires have the same diameter.
You can change the diameter of the front and rear tires,
that's just another tuning option (like adjusting camber, other tires and so on)

There is a rule for the tire diameter, the smaller the better,
but thick enough so it will last for A heat (8 minutes).

Sorry about that. After I submitted the reply I was a little worried that what I had written about the tire diameter might be misunderstood.

Tekin is right on about the tire diameters! The car just gets better the smaller the tire diameter gets. I saw on Lufaso's site that each time he went out on the track his rear tires were at 43mm and his front tires were at 42mm. I am currently running my tires at 44mm rear and 43mm front but that's because I use the old style Associated front end and that's as small as I can go and still maintain a 3.5mm front ride height. I run 3.0mm ride height in the rear. Once I get some cut down old style front end pieces, I can go to a 42 front, 43 rear set up.

No problem with the confusion, just a simple question, lol

I was thinking of getting the oldschool front end. As for tire size, with that CRC lowered bulkheads with 4 down insert and 44mm tires i was getting like 5mm ride height, lol. I think i will cut down my fronts to a 43mm to get an extra pair.

I just setup my front end alittle differently and ill see how it works, and ill let you guys know..

Thanks again

Jon

Well i got almost everything sorted out and its running great now... lol Its just been on and off with me but i think i got the setup down pretty well now.

I changed the front end setup, the tire size, diff insert, cleaned the diff up, new body, tweak fixed, thread locked the bottom screws on rear pod.

Here is my setup for now:

Jaco Purple Fronts-45mm cut
Associated L4 front end
1+1 shim (orignally i had both shims in the rear on the front end)
1.5 camber
*.5 toe-in
2mm shim under the front end for ride height

Silver center spring
50wt oil

Parma Grey Rears-47mm
CRC Lowered Bulkheads-#2 insert
2 shims on right and 3 on left i believe

Stock Monster
LRP Q2
Airtronics M8
Fukuyama 4 Cells
Parma Speed 8 Body

Thats should be about it, let me know if i missed anything. I got my Trophy Race tomorrow and well see how i do. Hopefully i do well.

Jon

No prob. Just want to double check on the setting. I'll give it a try on carpet. I'm planning to use TQ Orange sauce on the tires. I'll let you know.

I use Paragon tire sauce


Well my overall run today wasnt too bad, i had some problems in the qualifers with people not letting me pass, but i finished 2nd in B main. So i am glad to bring some hardware home

Revz- I used that setup today and it was fast, just the people i was running with wouldnt let me pass which was horrible, i think i could have gotten A main, but i will take B main anyways.

Ill let you all know if i change my setups.

JD I ran my 12L4 last time but I'm eager to run the Hammer next time on carpet. Planning to run the Hammer on asphalt this summer but I can't wait. Thanks for the setup and I'll let you know how it goes. Did you put grease on the friction plate?

A couple of things I did when constructing the AH12. I add more CA glue to all the screw holes and inside edges as well. The chassis has so many cut outs which is nice for weight savings but may be a fragile. I also filed down the battery slots at an angle to lower the battery down bit and made them stay better on the chassis. I then also covered the slots with CA glue. What's cool about 12th scales are the interchangeable parts. I'll just transfer my 12l4 front end and other parts to the AH12 and it's ready to race.

I did about everything you said above, except file down the battery slots which i should have done.

Thats what i did, took the L4 front end and put it right on the hara chassis. I also took CRC Lowered bulkheads and put those on the rear. So i pretty much have a AE,HAMMER,CRC conversion, lol. I will have some more updated pics in a bit when i get the camera ready.

Ill keep you guys posted.

Default hara question

hey hammer 12 fans:
i converted my 12l4 to the hara. i'm pretty happy with the result, although does anyone know if there's a stiffer carpet version of this chassis?

also has anyone tried the reflex 12 front end on the hara? i assume that's what the middle two holes are for.

thanks!

None that I know of regarding the stiff chassis. I do have some 3mm carbon fiber sheet lying around and I feel like making one without the cutouts at the front. I haven't tried the reflex 12 front end but I think the 12l4 front end has everything for a good front setup.

I have had a reflex 12, but i havent used the front end on the hara. I would presume that you can use any front end you want. The reflex front end can be a pain sometimes with all those turnbuckles, but i hear that the reflex front end is one of the better front ends.
