1) the ESC wire will not reach the stock receiver box.
2) the on/off switch will not reach the front box
3) what size and lenth screws are need to mount the Tekin to the losi mount.
4) can I rotate the front plate so the motor wires are are in a better position.
5) What pinions work best with the losi mount
6) What gearing should I start with running 5S ( I think stock is 18/46)

Thanks in advance

#3 If you go 5S drive several teeth in pinion or hang on

#4 From what you say above the ESC is NOT calibrated properly. The EPA must be set to 100% and then you can reduce EPA for either brake or throttle but not increase either. You say 90% which in your case could easily be 100%

#5 Is the ESC updated to the latest firmware?

#6 Brakes will eat run time and could lead to shorter times too

Hope something here helps you out...

I couldn't believe the defference on how the car felt just with that little bit of extra weight. It just felt lazy. Of corse my car was setup for 4S but if you don't need the power I would stay will 4S. If you are running a lower kv motor thats a little different. Running a lower kv motor and highier voltage is more efficent and will run cooler then a highier kv motor and lower voltage moving at the same RPM's. At that point you got to make the decison do you want more to be more efficent, or more balanced in the car. Of corse you can run a highier voltage and lower mah to get the same weight. This is just my opinon on the subject and it may differ from others.

I am running 16/44 and it feels awesome and it keeps up the 2650 on 4s that most of the other guys are running. Here is a vid of one of the local club races, mine is the one with the orange wheels.

This is very good info. I like the Drake setup a lot so I would like to stick with it. I think my problem is that I do not fill the shocks to allow for full rebound. I usually set mine to rebound about 3/8" as instructed in the Nitro manual--maybe that is my problem. I need to set the droop too and then worry about the ride height.

I have the 1.0 buggy with the Losi conversion kit. Just recently purchased used from here.

Here is my concern:

I have the 15t losi mod 1 pinion.

When I install that pinion, it sounds like the pinion and the spur is not meshing properly. When it runs, it sounds quite loud, and it has a rough feel to it.

The roller itself is smooth (without the motor), and the pinion and spur it not loose or too tight together. So I don't know how to make it sound like the gear meshes together better.

(Someone else also pointed out that the losi pinion comes loose, and it happened to me too on a test run)

Any suggestions would be great, and thank you.

are you running a metal spur or a plastic ? is the spur touching the mount ? i used a .1 shim on the flanged bearing to keep the spur from rubbing on the mount.

FWIW i had my first issue with the new RX8 System today....it's workable for now but tekin will be getting a call on monday for sure.

Hi Integra,

Should the spur be plastic or metal? It would have been the spur from the losi conversion kit.

The spur that is with the conversion is plastic. Mine is also a little on the loud side, but not too bad.

I have losi 8ight E 2.0 with 45t on stock center diff. Got the center smart diff(losa3601) and it has 48t and rubs on the chassis. Looks like 43t, 44t, & 45t are the correct spur gears for my car. Its says its a dirrect drop in then why would it come with a gear thats to big to fit in the car?

direct drop in for the nitro buggy, not for the electric.


just change your 45 spur out for the 48, as it is a direct swap. just becareful when you take the spur off the smart diff that the guts dont spring out everywhere

If you post in the busy hours you'll normally get a response within the hr....also PM'ing a user who's all about that 1 brand would work very well.

Sounds like your gear mesh is too tight.
