Hi guys. Greetings from Malta.

KENNETH TAN.

Quite right. I would have thought that the SD would be a light car but in fact it is much heavier than the BD car.

My SD has the Special alluminium battery hold down, and an aluminium motor heat sink extra. However I have alloy drive shafts as opposed to steel, and titanium screws all round, and still it weighs 1520 grams with a very thinly sprayed bodyshell.

The BD Special needs some 40 grams of lead to bring it up to the mandatory 1500 gram weight limit.

I don't know where to start making the BD lighter. Well I do actually. That centre shaft alone is stupidly heavy. I must try modifying a carbon TC3 unit till Yoke can supply theirs.

regards

Joe from sunny Malta.

I'm getting a little oil around the bottom of the shock shafts, but I'm not getting any squeaks in the shock. It could be the oil that I coated the o-ring with in the first place when assembling the shock.

Yeah. That shaft is impossibly heavy.

Heavy? Out of the box, with motor, electronics and body it was .6 ounce over ROAR minimum. Titanium screws saved an ounce.

Does anyone have a clue when Yokomo is going to release the aluminum pivot blocks, and possibly some graphite suspension parts? I was thinking of getting the Barracuda which I hear is extremely strong, just hoping I did make the right choice.
I am hearing how free the drivetrain is on this car, but thinking of getting ceramic bearings still, does anyone think there is a need for them?

Randman,

I heard that the graphite suspension parts will be available end of May.

I asked myself if I should buy the ceramic bearings but they are way too expensive 129.99 for the SD, I think I 'll stick with regular bearings and clean them regularly.

A friend of mine has bought ceramic bearings for his TRF 414 and he regrets because they are not better overally speaking, they are just lighter...

I would buy some spare parts instead of ceramic bearings, think about aluminum dogbones and option parts to come...

Randman:

I was able to get a full set of Teflon sealed bearings for $26.00 shipped. it's a comprimise between the stock and the Acer bearings. $130.00 for bearings is way too much...I think on the track you won't be able to tell the difference between expensive and cheap bearings...

Thanx Sosidge! I'm getting the same towards the bottom.

csf0623- I was getting a little oil by the top cap but by the second or third run it stopped and the shock still felt fine. The only thing I can figure is that I built the shock with too much oil and it forced it's way out because I still can't feel any air in the shock.

It amazes me to see people worry so much over bearings. The kits bearings are very good. I got to see a fellow board member's car yesterday(CIVIC91) and he could spin the tires and his drive train would spin for what seemed like forever, much longer than his 'Cuda. All he did to them was clean them out with a ultrasonic jewelery cleaner, then re-lube them with light bearing fluids. Thats it!

My car spun for half as long as his, and I haven't even cleaned the original fluid out of the bearings yet(although, after seeing his car, I'll be doing that today ).

I would think that there has to be more cost effective stuff to buy, than a $130 set of ceramic bearings.

I should have Matt and Davids setups on my website tonight sometime. I was too tired and sunburnt to do them last night. Especially after my crappy weekend, in sedan. First heat, car stopped on the straight, didn't know why. Second heat, broken caster block on lap 2 after bouncing off a car that crashed in front of me, into the boards. Third heat, car stopped again, found out it was my ESC overheating (GM SX9). Forth heat, car was extremely loose and pulled it off so I didn't break anything else. I hope the Reed Race doesn't go like this.

Default graphite parts

I noticed that the servo horn was made of carbon plastic, it looks pretty stiff and rigid .
will the future carbon parts will be made with the same material?
will they have a different design? the shock screw holes are placed at their weakest point.
