Dave the front of the shell has a gap all the way round it, i think this will allow a fair bit of air through.

Also where the steering linkage goes, you can cut this back further if you want too. I cant see there being any problem with thermalling, i havent come accross any problems.

I think you can drill some holes above the fan for the brca meetings but if you are doing euros etc you will get ur wrist slapped

Right, I am obviously being an idiot with the slipper, but...

How on earth do I tighten/loosen it!?!? I can't get to the nut once its in the slipper in order to grip it so I can either tighten or loosen the slipper clutch!!

Do the instructions show the wrong nut, or is there some tool in the kit I can use to grip the nut??

No it's a feature.... until the tool comes out....stick a flat bladed screw driver in there for now

DaveG28 · #24 22-03-2008

Grr, not having fun with this build so far, I'm useless!

Ok, have used theflat bladed screwdriver, but sadly the result is I now have a bent (but hopefully tight) slipper screw!! And no part number in the kit for the slipper screw!?

Also, have I managed to knacker it or is it right that the whole slipper assembly/spur is off kilter, it isn't straight at all now I've mounted it into the chassis. Its all pointed to the left front and right rear, have I broke it or does everyone else have the same thing?

I dont know the part number, but the spur/slipper pads look pretty similar to associated ones...I would think an associated screw would fit.

You mean the drive shafts etc dont run down the centre of the chassis?..thats normal

DaveG28 · #26 22-03-2008

Sorry mate, hard to explain what I mean, I think they all do the same from looking at pics, what I mean is that the spur gear is not straight across the chassis, I don't have the motor mounted yet but it looks like the mesh won't be straight as the spur is at an angle.

stuhurley · #27 22-03-2008

Has one of the slipper pads moved?...just been looking at mine and it's pretty straight to be honest

the spur gear has pretty much the same clearance either side of the slipper support and seems to run straight enough.

can you take a pic?

DaveG28 · #29 22-03-2008

Can;t get a pic until Monday, but yours helped thanks, in as far as its confirmed mine is knackered!!

Not sure how though, my outdrives are out of line as much as my slipper is, the entire assembly is off, in an angle similar to (though I don't think as severe as) your rear cvd.

Really

, I wouldn't have thought the slipper mounts could be wrong as they are bolted together, but can't think what else would put the entire unit out of line. I know I have the bent slipper screw but I would have thought that would have created a wobbly effect, not a smooth but always out of line unit.

sparrow.2 · #30 23-03-2008

The slipper screw bends because of the spring under the nut and having to shove a screwdriver up the outdrive to hold the nut. It doesn't actually do anything negative to the slipper.

I would have thought your slipper pads had moved while you were assembling it to get it completely squiff...

stuhurley · #31 23-03-2008

Are the alloy mounts out of line ? ...sorry still trying to work out what part isnt straight...

I'd take it all out again and start over (just the slipper and mounts

).

If the mounts line up straight, then its your spur/slipper. Take it apart again and make sure the slipper pads are in the slots in the spur

DaveG28 · #32 23-03-2008

I'll post a pic tomorrow night, it's the entire slipper assembly, including outdrives and spur, which look out of line compare to the alloy mounts. Which seems impossible to me! I'd have though if it was the slipper pads it would look wobbly as you spin it, but this stays consistently out of line in the same direction!?

Wondering if its optical illusion!!

DaveG28 · #33 24-03-2008

Ok,

am charging my camera at the momnt so will get a pic up asap, but, and I know this will seem weird....

The problem is that the outdrives have not gone on the bearings "straight". So its like the inside of the bearings you pt on the outdrives are not straight and therefore the whole spur assembly mounts off true.

Could this be the shims, as these bent as they went on? Other than that, anyone know why I'd have duff bearings!?

DaveG28 · #34 24-03-2008

Haha, talking to myself here but this may come in useful for anyone else building the car:

Ok, found the problem, it was how I had assembled the slipper mount with the two nuts at the bottom which have a screw in each side of them. I had tightened them all up with one side of the mount offset compared to the other, which is what then put the bearings etc out of line. Just reassembled it and the problem has disappeared!

stuhurley · #35 24-03-2008

Glad to hear you've got it sorted

DaveG28 · #36 24-03-2008

Next Question!!

Not a biggy, haven't got calipers with me and was wondering about the ball cup size on the kit, for the shocks, are they 4 or 5 mm, or imperial, does anyone know? I want to get some spares!

DaveG28 · #37 24-03-2008

BTW, EASILY the nicest shocks to build I have ever had, certainly puts Tamiya to shame!!

Once there's some spares knocking about, may have to get another set and out them on my 501X!

Dan Cockill · #38 28-03-2008

yer i agree very nice shocks

its not really a build question but i thought it would help
also you might want to be careful when you put your batteries in because you might short them out if you touch them to theslipper mount i almost did it so me and kev put a peice of foam over it to stop that

DaveG28 · #39 06-04-2008

Ok, two more questions from the build (I have NEVER used a shaft drive car before so apologies if these are stupid questions!)

I've put the gearboxes together and on to the car and two things are apparent:

1. There are bad tight spots in the drivetrain, not knochy all the time but just tight spots. Will these improve with running?

2. The rear diff case overhangs at the back when attached to the chassis, meaning dirt can get in to it. Is there any reason for this? I'm pretty sure I have done front and back correctly, so it seems odd to me? I am planning to just tape over it but just can't see why its there?

KevLee · #40 06-04-2008

Depends how bad it is? there may be some tight spots that will go with running in. As long as its not notchy, if it is, it may be because the bevel gear is shimmed too far and is clipping the diff plate.

2. The rear diff case overhangs at the back when attached to the chassis, meaning dirt can get in to it. Is there any reason for this? I'm pretty sure I have done front and back correctly, so it seems odd to me? I am planning to just tape over it but just can't see why its there?

Have you fitted the rear brace yet? the brace locates in that gap and covers it

hope that helps
