[mog ruith]

well jimmy if you had those pic pls post here
anyway i got myself fluorine coated balls and carbon reinforced m parts
should get that carbon reinforced a parts too if i had known

[antnee]

I realised earlier, in my big crash, it also broke the top of the shock, the cap bit, Ive glued it as it was only a little broken so I'll see how that goes!

Not doing very well with this durga

Second race, 6 laps it, bit of a griding noise coming from the rear take it apart to find

Shreded rear diff

not happy as I thought the diff's were fine, but it was obviously not tight enough as the metal rings are still firmly on the plastic drives

[jimmy]

Animal! You should always check the diffs, get into the habit of just twisting a wheel round every time you hold the car. The diffs on these cars (apart from that naff plastic holder) are really very good - but like any diff they need looking after and especially when new they will loosen.

[mog ruith]

maybe who knows 3 or yeah racing will come out with an alu diff

[DCM]

it ISN'T the diff, but if you are having a diff that is killing itself, then replace at least the diff nut, dip the screw in some threadlock too. You can upgrade to the steel diff's, but I just done a whole national and two club meets on a 5.5 sintered motor and not had an issue, I just regularly check diff tension. If you don't, you will stll melt pulleys with the steel diff outdrives.

I thought it was all ok, untill it just started going slower and slower

Hi all,

Was wondering if any one has good setup tips on racing the DB01 on carpet (smooth surface).

My DB01 simply doesn't want to turn. As its a Tamiya race, we have to us the Tamiya tires.

Any input is welcome. Thanks in advance.

[jimmy]

limit the rear droop, that'll stop it hanging on for so long and allow the car to turn.

Try my setup that I posted in the setup thread. I used that on a track where all but one of the corner apexes was on carpet and it worked pretty well for me.

The key change for consistency on high grip in my book is putting the rear shocks on the outer hole of the wishbone. Limiting droop makes a difference but also makes the car less stable on the bumps, personally I prefer to get the wheel rates stiff enough to limit roll without compromising the bump handling.

I am finding at the moment, I am putting limiters in the 501X shocks so they are going back to giving the same amount of droop as the kit shocks, the BIG droop seems to hinder more than help in corner performance.

Still got a nasty rear kick over sharp bumps though.... going to have to invest in pistons me thinks

Any shops in the UK stock the diff pulleys?

Thanks for the advice. Will try out.!!

Just got by Durga kit, making the differentials and the manual says "be careful not to overtighten" but I've also heard there are problems from having them loose so what "tightness" should I be aiming for (I imagine I will have to retighten after a few runs).

Realise it's hard to describe but should I just tighten as much as I can by hand using a small allen key or will that be too much?

Google is your friend

I didn't try THAT hard but I couldn't see the diff pulley on demon? the one way pulley is different, I do have a spare of that but not the diff pulley.

Hand tight (normal hands, not builders hands!) on initial assembly, check once in the car, recheck after a couple of runs.

Basic setting is not to slip easily (hold the spur and one wheel and try to turn the other), and the diff action should be smooth but with a little resistance, not spinning free.

Thanks, that's what I have done, will crack on with the rest now

I was wondering if any of you guys could suggest an alternative to the urethane bushings that fit into the Diff joints? They are the pink circular foam thingy's. Thanks.

[scotoap]

A.J.Gee, I make my own (Pink Foamy things) from old bumper rubbers or similar dense foam.
I have a section of broken ariel tube, which if you press and twist into the foam will cut a roughly cylindrical section which you cut into the desired length; hope this helps.
The same thing I also use to stop dogbones rattling in the outdrives.
