losi 2.0 shocks
just woundering how some of you guy's re-build process is with these big bore shocks .I have treid to do it the way the manual say's and it doesn't seem to work properly.I can't seem to get the matached properly i.e. same rebound and to extend to the same length .bert

I think he's talkin bout the rebound after pumping them up.
When you let go without the springs, how far the shaft comes back out.
They get a little back pressure.
Also when you put the two shock ends together and push them in they are supposed to collapse at the same time.
If one is stiffer than the other, I just crack the top on that shock and let it bleed just a tiny bit at a time til they do collapse at the same time.
I've also been told not to worry too much about it as long as there isn't too much oil in there to cause a "hydrolock" which will keep the shaft from it's full travel.
Of course too much air is also an issue. Just need to keep playin with em.

Here is a online video on how to rebuild your shocks. I've used this way to rebuild my shocks and have never had a problem. Try it out:

anyone had the problem with the rear diff pinon and main gear be extremely rough when rotated. I think its causing excess drag in the driveline. The 8ight nitro thread said it was a semi common problem and just to run it alot to get it to mesh right, but i dont know if thats the best idea

The heat sinks appear to both be from Integy:

They have several similar to the other one, but most of the ones that are closest to it, have fans on them:

They are still working very well. I charged up my battery to practice at the track. When I got there, it was still wet and muddy. So I left and ran the car out behind my shop(I like to store my Lipos 80% charged). So to burn off some charge I ran it around in the grass for several minutes. Normally, this is a surefire way get an electric powered vehicle very hot! After several minutes, I hit it with the temp gun. In 70 degree weather, the motor was about 105 degrees! That's pretty impressive. The heat sinks are working very well.

Yes, I found that reducing the drag brake to zero helps a lot. There is still a lot of drag in the drivetrain to overcome, which still must be compensated for during jumps. I have found that as I get used to the car, my jumps become more consistent and level. Braking is the same. My brake finger is becoming accustomed to the necessary throw to stop the car depending on the speed. Very slight movements are required for proper braking.
This thing really is blazing fast though once you begin to get a feel for it. I am going to try running a 16 pinion today. I will report back what i think. I have only run a 13 since getting the car.

I went ahead and ordered 2 of these
they were on the integy site that you listed. Im not taking any chances anymore with burning up electronics and missing races

Yes, with the losi 16 pinion the car ran much smoother and it felt it was easier to correct position in the air during jumps and get initial traction. I think this was a result of being able to get the tires greater RPM to correct position in the air. To me, it felt smoother and somewhat like a nitro. I really like the feel of the 16 pinion, I am just worried about temps. I don't really feel comfortable running the 16 because I was able to get 165 on it during a 45ish degree day. I am getting to the point though where I just want to say screw it to worrying about temps and throw the 16 back on and just go for it. I added a heatsink to the rear of the motor, so I'll see how that works. I haven't any problems with the losi system thus far.
