Great news Fredrik

Well first Meeting over. Had my best placing yet (3rd out of 12) This is including a couple of ex state/national champs.
Track was very rough so just using Yellow springs, 35w F and 32.5 R Kit sway bar, 7k F 3K R diffs and Holeshot Tires. Did play around with rear camber during meeting.
Was bottoming out of entry to our triple which cause a few dramas in first race, so had to back off and only do a double. I'll remove 1mm spacer from shocks. Track was to rough to firm up suspenion to my liking, but happy overall. (apart from my 201XM letting the smoke out of the ESC in warmup)

Car was built in a hurry so still some little things to finish off. I had to put extra shims in the diff as I wasnt to happy about the play. I forgot to order the Red O-rings for diff, after one meeting they are weeping already. One of the suppliers forgot to included my alloy steering rack so only had kit plastic in reverse.

Guys do you use any spacers inside the rear shocks?

I only use 1mm, all I did was set the rear so at full droop its the same level as the front and it seems to work well

[D-StyleNZL]

Yeah I used the Kit standard, but will be removing a couple. If you have full droop you may run risk of popping shafts out. Pitty these dont come with travel adjusters on the arms like other brands.

Any one have Part number for the Kyosho Diff O-rings people are using? or are the Tamiya Red diff rings ok to upgrade to?

Tamiya 42259

I have about 16 pack through my diffs with the TRF 42259 and zero issues with the diff fluid leaking out

[patez]

the red trf one have worked for me aswell. zero leaking. i have also used one extra 0.1mm shim on the outdrive to reduce play (thicker side, outside of the case)

[SiR_Dave]

Waiting for a few new things to be released .... Brass weighted front and rear skid plates.... should have pic's soon

[guinness]

OK this is my first run with the 503,very technical track with lots of sand on the AstroTurf.
Done 5 runs (open class wile racing properly with my 2wd) wile I was playing with the settings ,more testing to come.

[caneye]

can you use either B44.1 or BMax4-III rims with this car?

(front & rear)

[SiR_Dave]

B44.1/2 are the preferred wheels to use with the TRF503 proline or Jconcepts work the best....

[marco NL]

Rudebits TRF502 weight fits perfectly on the TRF503

total weight 56 grams





I use B44.2 body and jconcepts wheels

[SiR_Dave]

Man that belt is close to that weight in the rear.. I would file it down a bit if your wanting to have any rear belt life

[marco NL]

Dave

I have a little file it I think it is no problem for the belt
I have the belt in stock

[patez]

Is the TA06 front ball differential set direct fit? The kit is only 19$ at rcmart....Altought I have started to really like my gear diffs with 5k oil all around.

[SiR_Dave]

If that's the Alloy front Ball diff kit 54305.. I would jump on it for that price!! that's over half off!! and it has the blades as well... Why not pick up two if them if your looking to run front and rear ball diffs and save some weight at the same time

Nice...

[patez]

Ordered! Its still quite easy tuning option to try out.. I guess the diff balls are the crappy steel ones.. so also needed some ceramic balls.

[SiR_Dave]

Make sure to get a good thrust washer set from AVID if you can for it ... Carbide or Ceramic

[muratti]

Did you guys have to shave a lot away from the bumpers to clear the pulleys and how did you do that? Dremel?
