Stupid screws?
 

Hey i just sttted building my madrat kit but i have some huge problems with the screws. I cant tighten them all the way. Ive tried all my allen wrenches and hex drivers but they are just spinning around inside the screws.


Have you had any problems like this?

Hmm i think its only a problem with the 4 screws in the front bumper. I just dont know how to tighten them :(

Mad Rat kit screws are pretty bad, I found that over time I rounded off a lot of them and the only way to get them out was to dremmel a slot into them. These days I've upgraded the screws on the entire car with stainless steel and where possible use cap heads as these use a 2.5mm key instead of 2mm - helps no end and takes all the stress out of needing to replace bits and not being able to get the screws out.

i found that n i replaced pretty much all of the screws.......pain in the back side ..but the quality is just no there

Ok i gotta buy some new screws then :( but ive only had problems with 4 screws. Its just really annoying!

yeah i know ....my prb was the screws in the front bulk head same as every one elses from looks of things ......i also changed em all as some ppl have rounded theres off so i prevernted the prob befor it arose

My dad tryed using a torx screwdriver and it worked!

One question though. I just builded the diff but i dont know how tight its gonna be?

well i run mine a quarter of a turn off fully tight ..i dunno if that is correct but thats what i do

Okay thanks!

These screws are making me insane!!

If there is an interest i can supply full high quality stainless steel screw kits for a madrat?

My lhs has a lot of screws so its not gonna be a problem. Its just annoying that i have to buy screws!

Just bought some expensive titanium screws.

Oh my god what is going on!? These screws are just as crappy :(

it maybe that the screws are too thin or short for the holes in the car?

No thy are same size as the standard screws. Man this is annoying :( i also ordered an aluminum hex driver with the car but its not in stock

Are your hex drivers in good condition?

If they are worn you will strip the screws just as badly as if the screws are worn.

Always worth having quality tools to hand if you want to do a quality job.

PS A lot of the titanium screws sold for RC are pretty poor quality as well.

I dont think the tools are worn. Ive tried many allen wrenches and hex drivers. Its really annoying that. Didnt get the hex driver that i ordered :( im always unlucky

are the ones you are metric or imperial what do the say on them ie 2,5mm, 2.0mm or 1/16 5/64

The screws are called m3

what size driver are u using not screw size

Get yourself an EDS 2.0mm driver, you will have no problems, even with the standard screws

Im using 2mm drivers/wrenches.

Minke i have ordered a "high end" 2mm hex driver but its not in stock so it would be a little stupid to buy one more

buy some decent tools

Omg did you read what i just wrote?

I dont know what 'high end' tool you ordered. I just recommend the EDS range. I rounded a few allen keys off trying first time, this one takes the old screws out, even with damaged heads.

I just saying high end so you know its not a cheap crappy tool. Im gonna buy the hex driver my lhs has. 12 poundsnor something like that...

I just have a question about the a-arms. I can move the left arm up and down freely but the right can only move up and down a little bit. Know whats wrong?
(cvds and turnbuckles are installed)

sounds like the cvd may be hitting the nut from the diff screw, if it is all assembled (correctly assuming) then try taking the diff screw assembly out and put it in from the other side. Instructions are pretty vague in the manual

Okay thanks! Do i have to take the gearbox apart?

If the gearbox is all assembled and in the car, then no, you don't. You can take the whole screw out and re-insert from the other side. Just be careful.

again this is another common problem fella..........make sure you have the diff in the correct way [i made that mistake ] the screwhead should be on right hand side ..should solve it if not ..there is always the washer trick

The washer trick? But thanks im gonna try it :)

I think i did it right :) thanks

Oh no no no :( the plastic thing that holds the nut in the diff is broken :( dont know if it can be glued ?

you broke the diff nut ...howd you manage that ...

I've replaced all the screws on all mine because that's the worst part of the car. But you can build one without stripping them IF you use a torx driver for the entire build right from the start, if not then your sure to ruin at least a couple screws and a few allen keys also. The diff is not the same length on both sides so you have that in back to front

Wayne i have no idea :( but i think i could make one myself.

Nicefrog: okay but i think it could be my tools because i also broke the new screws i bought.

Sory but u got another question. When i put oil in the shocks and put the cap on they feel very good and responsive but after a few hours they a alot less responsive. Whats wrong?

are you using the kjit plastic shocks? .......they are not of the best quality putting it politly. ......i replaced my shocks with a set of ally ones ...depends on what your gonna use the car for bashing or racing?
bashing ..then the shocks in the kit will be ok ...but for racing id look at getting better ones when you can

I thought the only problem was the shock caps? Im only gonna be racing with it. Nothing serious though. Im gonna buy a hudy hexdriver today
