HI, new to 1/5 here. I got a used fg baja and the front disc brakes work great, but the rear main brake does not seem to do much at all? I can look through to the brake pads and see that they are clamping down but they do not seem to be clamping down enough to stop it? Ideas?
 
the stock rear brake is a bit pants. you can fiddle with the lever ratios by moving teh pullrod closer to the centre of teh servo horn, and the prake lever further out, but that's about your lot.

it's worth looking at the alloy brake upgrade.
 
The alloy brake upgrade is great. But try to drive it without the front, you might be surprised, if might hook up more than you thought. Don't drive it too fast at first though, just as a precaution.

Thanks for the input. How will a stronger radio tray help?
also any one have the link to the aluminum upgrade brakes? thanks for your help
 
With your radio and receiver on, but engine not started for safety, try accelerating, then braking.
At idle, there should be perhaps 1mm slack at the back of the rod adjuster - on the back brake. If there's more, then you may close this up, so the brake is not binding at idle / rest to approx 1mm.
Now try braking hard, and look at your (plastic?) radio tray - it bends to "£$%£"$% !!!!!!!!!!!!! :(
This is why the alloy radio tray, with good location, or as Voo says with at least more support posts making it's location much stiffer, is MUCH BETTER - a good solid, non flexing location of your throttle / brake servo.
If there's nothing on FleaBay currently, they're often popping up and are not expensive.
 
Do you think If I started to make them, they would sell good?
I have the contacts to have them made cheap.

you need to update your location:)

as for the alloy radio trays they are already being made cheap and on uk ebay

under the "race" logo:clown:

i just added an extra alloy post on my marder and that works just fine no flex

you can just make out the 10mm dia alloy post on this pic:clown:
 
What thickness is that Trebor? I was thinking of making 1 but wasnt sure what gauge to go for - was thinking either 2.5 or 3mm.
 
I got one custom made from 2mm ally sheet to my own design (for single steering servo) which is plenty stiff. It only cost me £8 from a guy called 'ProfileMan' (or maybe 'profilemen'?) on fleabay ,based somewhere in Redruth Cornwall.

If you wanted a double servo set up, 2.5mm or even 3mm alloy would be better because the cutouts are larger, so the tray needs a bit mor material to keep it rigid.

I posted my plans on an earlier thread, feel free to steel, copy, or change them
