HELP ME AND EXPLAIN...........

i here theres a 508 trf out i know ive never heard of either apparently some aussie who has moved here has one its trackside rumour apperently new chassis and new gearboxes for the worlds

[TRF_Tastic]

I know about the new chassis that is coming out, cells 3mm further forward etc etc... but as for gearboxes Im afraid not.

If anyone knows anything about this post it and pref piccys please.

[jimmy]

I asked Hupo about some things - hopefully I didn't sound too insane and he will understand what I asked. I've heard some similar things, but I've yet to see anything myself.
The only thing you can't buy that I've seen is the new camber mounts, stronger versions.

[DaveG28]

I'd have thought they are bound to bring out a worlds car, look at the 415, it has 415/415ms/415msx/415msx mre. Pleanty to choose from!!

Seriously, I'd imagine part of why it came out nearly a year before the worlds would be precisely to allow them to change it again. Although new gearboxes and chassis sounds quite major!

[mobilow]

I just tryed the 501 the first time offroad. My car is very loud, it sounds like 10 Parts are rolling in the chassis instead two belts. Has anyone the same problems ? also the rear belt jumped of the diff, the tension was ok, just out of the box using the settings from tamiya. I ve heard the spur is incorrect, is there a better solution for the stock one, that will calm down the sound ? Also I add a 3mm washer into the rear oil damper, cause the dogbones also rumbled a little bit. All in all with the one way pulley its good to handle I really like it.

[Colinevan]

I thought mine was noisy as well, Jimmy ran his today ( same race) and his sounded just like mine - noisy lol.. Theyre deffo not quiet like a 2wd.

I have slight spur probs in that they dont run true, when the car was new and with a new pinion, there is tight spots on the spur , i think thats where the noise comes from.

Set the spur so its a nice combo between play and a nice mesh and check it all the way around for eveness.

Thanks

[Colinevan]

To answer your last question, i believe you ran run b4 spurs as well.

Im sure someone will clarify.

The noise comes from your pinions not the spur. You definately want to run long pinions on that car otherwise it'll be very loud...

[jimmy]

I run short pinions but get 100% mesh, depends on your shaft length (haha).

I am running 87t B4 spur gear on mine colin. I had some noise today under braking, sounds like the rear diff is slipping for some reason but not under acceleration, just braking.. odd.
Car was good, too soft though since I only changed the springs from racing at Tiverton, but overall great.. Stood up well to the harsh southport track.
That track is just too hard for me though - I simply can't go fast down that mental back section, and I lose lots of time because of it.

[jimmy]

Mobilow, is your rear diff ok? unless you replace the balls with something good the diff will slip in my experience on our high traction tracks. That would sound pretty nasty.
Main thing to check is the spur though, I took the kit spur off as its too big. The B4 one is better all round. I'm geared 15/87 with the LRP 3star brushless.

[GRIFF55]

Raced the mid west regional at oswestry today and the car was making clicking noises like a junping belt, couldnt see any probs but after checking diffs, slipper etc. it turned out to be the rear belt pulley on the layshaft was very badly worn(only done 5 meetings).
BEWARE.
Apart from that and a snapped diff screw, car was great

[jasonrcb]

im with you there griff my back diff collapsed ysesterday and im not overly happy about how quick mine is showing signs of big wear rate

[TRF_Tastic]

I have found that the drive train does wear on this car if it is not given maximum love!!

After every meeting the diffs come apart and get cleaned and rebuilt, things to look for are as this car has slipper style diffs is excessive wear on the inner and outer faces of the diff races, if showing any signs of wear throw them out and replace, you can re polish the races but I dont think that it is worth it. You should get 5-6 meetings from the rings if you keep the diff in tip top condition. Also if you use the diff shields that should increase your diff life as well. And just to reinforce what Jimmy said get some decent ceramic diff balls, there is a very nice advertiser on this forum (KANZEN) who supply some very reasonable diff replacemtent ceramic diff balls which will increase the life of your diff.

The belt tension is a big thing on this car as it will chew belts and more importantly the centre pulleys that they ride on, I have had one go completely, this was after 10-12 meetings but it still went and nearly cost me the whole day. I would stock up on centre pulleys as they are difficult to get hold of at the moment, as they are used on the TA05 and 415MSX MRE and MSXX.

[bender]

The only comment I get about mine is how quiet it is and how quick

It's easily the quietest car on the track, 2 or 4wd.

I have run both the kit 96 spur and a B4 87 spur - both seem quiet to me.

I am using the Tamiya pinions - they seem to be pretty good.

[TRF_Tastic]

I'd agree bender, mine is quiet as well. The only time it makes a lot of noise is when something has broken.

[BORMAC]

Ive been running mine with low turn mods and the 5.5 BL motors and I can say with my sloppy driving that Im still yet to bend or brake something.Im also running the kit spur and genuine Tamiya pinions and I think the car sounds great.Sure the open diffs are pretty ordinary but if you dont mind the upkeep you can run a car thats very competitive.

[GRIFF55]

I totaly agree, only broke one wishbone and that was due to me!!
Just letting you know to check the pulleys

[mobilow]

Thanx to all the comments just ordered Kanzen Balls and a set of center Pulleys hopefully there will be an option to get one out of metal. I try to change B4 Spurs. Jimmy you re totally right the rear diff is totally bad after 7 runs I will rebuild it and seal it with some stickers. Hard testing goes on yesterday on dusty slippery clay track and the next sunday on gras hopefully taking the first points to the german championship. See also the pic its so much fun racing this car ...
