SC10 4x4 Thread
So after doing a bit of running around away from the track I noticed that my Pro4 was sounding and feeling a bit gritty. After disassembling sure enough it was filled with dirt. Luckily it does not appear as though there is any damage so after some TLC it is back together. I have spun the motor so the tabs and the open slot associated with them is facing the rear of the truck in hopes that it will help. Anyone else had this problem and what they have done to try and fix it? I am thinking about a small bead of silicon along the slot but do not know if that is there for airflow purposes. Thoughts?

...I have been testing o-ring seal for the center diff (my own design) and it seems to be holding up very well. Grease stays in dirt stays out, and the gear runs true.
Not sure about making this yet for others.
I also have come up with a hardened steel bushing for the diff out drives. I need more testing time with this idea but I can tell you there is zero slop and you still have the full support of the out drive bearings.

Congratulations on good race times and deveopment!

Regular old electrical tape works good to tape off slot on the Pro4 motors as well. I highly suggest to remove and disassemble your motor after every race(weekend) to clean and inspect for smooth bearings, sensor board tightness, and stator winding inspection. If you don't you are asking for a motor failure and I don't know about you guys, but $140 to $160 for backup motor is out of the question for myself. I would rather hit the track knowing what I have and knowing it has all been serviced. Do not forget to loctite the screws holding the sensor board as that is one of the leading causes of failure on these motors so I have been told. Avid also has some nice ceramics for this motor to those interested. One of the most simple motors I have ever had apart for service and bearing replacement.
I'm not sure if blasted is the corect word.."didn't work for me".."gave me the wrong pistons" would be much more like it..and if I thought all your products were junk..why'd I just buy a V2 diff? and I'm getting ready to order some discs..in my opinion it's done..after all if I'm selling products for ya..what's the problem..

Also weather you like it or not i am sending another set of SCTE pistons with your order, do what you want to with them! I dont remember your name so mention it in the comment please.yes, it will
If you lock the slipper so it cannot slip ?
*off power the truck will be darty entering the corner.
*on-power makes wheel spin accelerating out of turns.
adjust the VTS so 1mm to 1 1/2 mm of thread shows on top on lock nut .
Then go fast with ...
VTS slipper performs great , more traction & smoother acceleration .
Tip :
Lack of rear traction can be cause by many things .
tires
ride height
oil
piston
spring
rear toe
wheel base
slipper adjustment
radio
ESC
Tip

Yeah, I thought the same thing too which is why I bought it. Excited to try it out.
Would even like to see Wild Cherry try it out and see what he thinks. Maybe AE will make one in the future so he can

I'd be interested in seeing pics of the o-ring mod (CraigMBA?) is doing for the Center diff.
The spur using the center diff sure has a bit of wobble to it. Suppose it really can't be prevented due to the size of the diff balls (which are a good thing).
I'm guessing that the o-ring is used between the spur and diff ring (outside the diffballs? Which would help keep the diff lube in, and the crud out as well as help keep the spur running true. Am I close?

From my lawn dart fest on the first practice day at the new track the screw holding the front skid plate on has ripped out of the chassis. Is there anyway to get it to stay in or do I have to buy a new front chassis?
Also forgot to add that after the installation of my center diff I am noticing that my motor temps have dropped about 10-20 degrees. Im guessing that my motor revs are staying down now because of the lack of the slipper(aka using only the amount of power as I need now) and the extra heat from the slipper is gone now.
