Oh ok thanks Dus, I think I may have found the reason the car is going so slow, I took apart the transmission box and it all seems fine inside greased up etc, but now I have it all back together sat flat on the table I've noticed the big cog (above the motor) moves almost 180 degrees before it actually moves the motor round enough for both rear wheels to move, could this be whats making the car go so slow or is there supposed to be play like that? The cogs are aligned fine and they are close together so its not slipping.

no the gear isn't meant to move that much if you can find a set of the white upgraded speed gears it will improve the cars speed
can you remove the black gear and have a look to see why its slipping so much

I took apart the transmission & moved the outer gear by hand and the inside mechanism moves straight away all 3 cogs inside, maybe its the bar that comes out that the big cog clips to that is loose. Im at a loss as to what exactly it could be, The two parts that attach either side are on tight and the bars the go to the wheels are in place properly, so I'm baffled. Ill just get the upgraded transmission and rip this one out. At this rate all the Bycmo (HiTec) gear will be off the chassis lol. If anybody needs a resistor, throttle servo, msc original and a Kyosho 96435 and possibly a transmission box and a 540 silver can at this rate let me know. I've got a bunch of connector wires that go from the msc's to the motor and from the receiver to the msc etc all in a bag.

A caliper (I think) is something electrical you measure stuff with, like this; http://www.harborfreight.com/6-inch-...per-47257.html

Mine is the same as the one in the pic, I belive it is indeed the transmission I took it for a spin today and the motor and the cog in the pic are spinning but the wheels don't move at all. I took off the silver parts that are held on by Allenkey screws and put them back on tighter and it made no difference the motor and cog spins like mad but the car hardly moves. I'll supply pics to show you what I mean dus

That what my finger is touching is what I mean by "the silver things with Allenkey screws" they hardly spin when I accelerate on the floor but the motor and spur are spinning normal

they are cups
have a look inside the gearbox see if anything looks wrong and have a look inside the diff it could be the diff that's damaged
(it sounds that way to me)
its what happens when you go full speed forward then full speed backwards to make the car skid its why most of the bycmos
end up either in the bin, stripped for spares or sold on
if you pack out the diff with smurf poo (blue tack) it will give the car a locked diff
its a temporary fix that way you can order the upgraded diff i sent you the link to the other day and that will save you money trying to find a rear end that will fit and work

I thought that was the transmission lol I really do need to pay more attention, I opened up the black box on the rear of the car and all 3 cogs inside have all teeth intact and are greased up, what is the diff? Differential I'm guessing but where is it located exactly n what do I do jam blue tack in to stop it from moving? Also when the car moves forward briefly it make a horrible noise as off the teeth are slipping on the motor but I know for sure they aren't because I have the shell off and watch to see if they are.

Ah scratch that I had a look at the image break down on bay, it's the bottom big cog in the transmission box, funnily enough that is the area the noise comes from. I can't get into it to take pics to show you because who ever had the car before me has threaded the alen key screw on the left side the right comes off but the left is a challenge to get off, I shall try to get it off again without damaging the transmission and show you to see if you can see a problem. Would it be easier to upgrade to a new trans box completely or just to swap out the diff?

Here is the diff (differential) exploded I think your planet gears are damaged (3046) if you can unscrew the (0450) screws
then pack (3044)with blue tack then reassemble the diff and then the car it should improve the car speed

That's as far as I can get, If I remove the screw can I get in the diff to check it out or do I have to remove the other cup that the key is hanging from, that's the side with the threaded screw head. It's the right size but it spins once I apply pressure and the next size up don't fit so I'm kinda stuck if that has to come off :/

I would have a look in the diff
pack it with blue tack
try that if it's solves the problem then you have a car with a locked diff
you can get a new upgraded diff like one in the photo above
if packing it out still doesn't fix the problem then as a last resort I would look into a new gearbox
and back end and trying to make the car work

I can't seem to get into the diff. One side is loose but the other side won't come off so I'm guessing the other cup needs to come off to get inside the diff, but I can't remove the cup due to the threaded screw head this car is beginning to drive me insane lol

Really the cup needs to come off as from what I can remember there are two screws one each side of the diff if you hold the cup with a pair of pliers can you undo the grub screw in the cup if not then the cup might of been super glued on if thats the case hot water will soften the glue just be careful

I'm just going to get the diff upgrade off bay and get a new allenkey set and hopefully that will open up the locked cup and then I can swap over the diff as a unit rather than individual parts. Hopefully that will sort out the speed issues and the fact that the car hardly moves at all now lol. I'll let u know how I get on once I've got the part and fitted it. I'm going to get the diff sorted before I get the trans/rec set and fit those so hopefully it will be up and running with all the upgrades in a few weeks. Will I still need to tac the diff with the upgraded diff fitted? I'm asking because my esc (TEU-104BK) does not allow the car to go from forward to backwards straight away it has to stop still before the esc allows it to go into reverse would this stop the diff from messing up or should I still tac it maybe even epoxy glue it?

With the break function of the teu-104bk theres no need to pack out the upgraded diff

Did you get your hex's and wheels yet cant wait to see what they look like

Ah thats good news, that way I can just swap the full diff over as long as I can get that damn cup off . I haven't got the hex's wheels or batt yet they all came from the same seller. They was all supposed to arrive on wednesday but they haven't come yet the seller told me to wait until the upcoming tuesday and if I still haven't got them they will send out a replacement parcel. It was sent signed for and they supplied me with the tracking number but its still showing as being processed in the RM system, I thought it may have been down to the bank holiday but by the sounds of it the seller is having problems with RM not delivering parcels and them disappearing :/ Im looking forward to fitting the hex's and new wheels. They came with new tires the bycmo ones were practically new when i got them and the rear two are bald on the inside already lol WTH.

That sound about right
thats bycmo for you
I think the upgrades helped with the scrubbing
What tires do you have on it are they the super slippy ones (lots of little square blocks and hard)
Or the upgrade ones they have a great tread depth and are softer than the standard ones

Sorry for the long gap in replying dus I fell asleep. The tires are the ones with the block squares on them. I think everything on the car other than the spur on the motor was standard. The shocks are yellow the area behind the wheels is white plastic standard wheels and tires, It came with the yellow jetpakk battery pack the standard servos msc and trans/rec. I still haven't found the upgraded oil filled shocks the mags with the parts are on bay but there 8.99 each and the oil isn't in either of the packs i might just have to get some based on the measurements you gave me the other day. I've been looking online today at Tamiya TT-01 rolling chassis'. What would you say is a reasonable price for one there all coming up at about 70 for bare bones just shocks wheels and a fitted trans area no servos trans/rec batt packs or esc/msc. Some come with shell's.
