Got to run my XXXS for the first time this weekend. I ran stock TC with great success. I have the graphite conversion kit so my car was as light as possible. Car had lots of steering and was solid through the corners. I did not get a chance to run my MR4TCS to compare them head to head, but the XXXS felt as fast or faster through most sections.

I ran Trinity blues cause that was all I had for springs but was told Losi blue or orange were better? Only had time for three races, and the first two were getting used to a new car and new layout. As a side note the car was sooo quiet that I could hardly hear the car pass by! Lots of potential for sure.

I would set droop while the shocks are on. The droop screws are screwed in on flexible plastic so the measurment might not be accurate when you put the shocks back on due to spring tension pushing down onto the screws.

MauiBuilt Racer: thanks for the tip. one more thing, since you set the droop with the shocks installed, i guess the droop will directly affect my car's ride height? or am i wrong to asume that? pardon my ignorance, first time i've had a kit with droop screws. i was formerly a mr4 and pro3 owner.

When setting droop you may want to use the shock length instead of using the droop screws so that it more consistent. The plastic on the bumpers is to forgiving in my opinion.

another question, this time on caster. if i wanted to set my caster to 4 deg, i can either do it by 1) slapping on a 4 deg castor block/hub carrier and use 0F front kick-up or 2) use the stock 0 deg castor blocks and use the 4F pivot blocks. question is, although effectivly i am getting the same amount of total caster, will the car handle differently depending on what approach i take? i've heard that using the pivot blocks to acieve the desired caster will stiffen the suspension more as opposed to using the 4 deg hub carriers - hence a difference in traction and handling??? hope someone can help me on this.

nitrorcfan: thanks. am actually considering doing droop the old fashioned way - by measuring the shock lenghts. much simpler if you asked me. hehehe

Nitro RC Fan: You are spot on about that bumper flex!!! I sure would like to see a much more solid approach to setting droop on my XXXS.

Default XXX-s wet tarmac setup?

Guys

Anyone got a good set up for wet tarmac? Couldnt get my car dialled in last weekend at all no matter what I tried. Running Blues on rear, silver at front, 80wt oil, Pitshimizu narrow D20 tyres with standard inserts, rest of the setup is pretty much as per the kit. I know the oil is a bit heavy and will be changing it for this weekend coming, but any other advice would be useful.

I think the most important thing in the wet are the tires.
The ONLY tire that really hooks up even in standing water is Take Off's WSA.

Also, soften your car up a bit, 80wt with blue springs sounds too stiff for rain.

I'd try 57 pistons with 40 oil up front and 56 pistons with 40 oil in the rear.
Silver spring up front and probably pink in the rear.

chownr: What track do you race at?

Try this:
Shocks stood up front and rear
60wt f, 50wt r
56 piston f, 55 r
Blue spring rear, Silver f
2f & 4 degrees caster
4r squat
f droop 3, r 5
Camber link 1 from outside on front, one from inside on rear
Inside ballstud in rear hub, -0.5 degree toe in blocks
cells forward
5mm front ride height, slightly higher at back
1 degree camber all round
low roll centres
one-way drive

This setup done me proud at Aldershot last weekend, track was very greasy but car was nice and easy to drive.

Thanks for your reply. You have just re-inforced what I had kinda thought myself - shortening the front camber link, running lighter oil in the shocks and running more anti squat at the rear. Its one of those things that when you sit down and think about it with a little advice from others the solutions are obvious. Not so easy to do in the heat of battle on a Sunday though!!
For info I race at Leighton buzzard which is not a permanent track but is used Monday to Saturday as a delivery yard for a garden centre so tends to be pretty greasy, even more so with the current weather.

Ill give your set up a try and let you know.

Many Thanks

Carpet racers using foams:
Here is Craig Xavier's winning setup in stock from the Trinity Challenge at The Track in Maryland.

prototype (Wednesday, January 9, 2002, 12:37 p.m.)
Alright here's the setup I ran for the race.

Front: Losi 60wt oil, 57 pistons, Losi black spring. 2F Pivot support, .063 front sway bar, 4 degree caster block, arms spaced forward. #3 camber link position with .060 spacer under the outside camber link ball. Shocks stood all the way up (#4 hole).

Rear: Losi 50wt oil, 57 piston, Losi black spring. 2R pivot support, arms spaced in middle, no sway bar, camber link in #2/B also with a .060 spacer under the outside camber link ball. Shocks in #4 hole and outside on arm. 1/2 degree toe-in blocks backwards on rear.

1.5 degree camber and 4.5 mm ride height front and rear. TRC plaids/magentas. Batts forward.

I think that's it. I ran the same setup in Mod just ran more Paragon on the front tires for mod.

I ran 128/40 for stock with a 57 tire and 128/27 with the same tire for mod

Craig car was on fire but a lot of it has to do with the fact that he is a damn good driver.
