I have never had to boil parts so please help me out here.
do you bring the water to boil and then put the parts in for 15 minutes? Or do you put parts and water in pot and then once boiling start timer for 15 minutes?

Do not over think it Put the plastic in slightly boiling water (simmering), and leave it there for some time (I usually do 30-45 min). Let the plastic cool down in the water.

Presto... dinner served

Mark I did boil them. Even though i did boil them the part was going to break due to impact on a pipe lol. I ordered 3 sets of arms now I hope they will be here before next weekend.

Hello,

i often red about setup to use 7-7-3 and i tried it but i have a lot of front tire wear.
In a final of 30 minutes the front tires have no profile after 20 minutes. Thetas not normal for me. It is the same on tracks with grip or with less grip. On less grip tracks a can drive 25 or 30 minutes but this tire wear is horrible for me.

Has anyone a solution for it ??

A fellow racer that works with plastics told me that to condition the parts just put them in a ziplock bag with distilled water. No need to boil them.

Default RB damping system setup

Ok, so the problem is that I have that new system in box waiting to put it on. But I like to first get some feedback from somebody who has been using/testing it with MBX7. What kind of springs/oil combos you have been trying and what to try next, In RB own pages they told to use 1000/850 oils but there was no mention about springs.

1. Be more gentle with the throttle
2. Softer clutch setup (does the same as 1)
3. Ticker center diff oil, but the rear will break out faster on throttle...

Use same springs as with standard dampers.

So now i have a problem :

1) i am gentle with the throttle cause of the loose rear
2) softer than 1.0 springs in the clutch ?
3) this the problem with the looser rear.

I donīt understand: i have a car and should drive fast but cause of tire wear i should drive slower You are right but this is horrible or the MBX-7 is not a good car in my eyes.

Thanks for the solutions but donīt help me cause i tried point 1 and 3 (

Try 10-7-5, put the rear hubs in the upper holes and put the rear hubs all the way forward.

If you are roasting front tires prematurely, one of two things is happening. Either:
1. You are diffing out excessively to the front wheels under acceleration and spinning the tires like doing burnouts in a full-size front wheel drive car. Morgoth's advice addresses this perfectly.
2. You may have excessive toe in or out, which is like dragging the tire sideways down the track. Set 0 toe to SLIGHTLY toed out like 1 degree and you will maximize tire wear.

The front tires normally wear faster on any buggy. If the difference is excessive, try what the others posted as they are good ideas. Going up in the front diff like Billy suggested should be your first step. It will not only reduce tire wear but will take some twitchiness out of the car.
