Dremel with a drill bit lol
I just made the hole big enough to put the whole plug through

Hey guys! I'll be running my B4.2 on a medium sized indoor track. I'm going to run a 13.5 motor on it. What would be a good start on gearing for it?

The track is more technical with smaller jumps.

Thanks in advance for your help!

All of the small diameter drill bits that I break, gets used in my Dremel. Drill bits chucked in a Dremel makes a great cutting tool for plastic!

I haven't cut the holes in my chassis yet, but I'm sure I'll use a Dremel with an old broken drill bit to slot it out for the plugs to go through.

Well the Jconcepts ones look good and im guessing they work pretty well. Im a big jconcepts fan and havnt been let down yet.


Last questions, if i go over to BB springs do i need to change out my shock towers to b4.2 ones or are my current ones fine?

Thanks for the info guys[/QUOTE]

will need to add 2mm spacers if using 12 mm shock & old b4 tower.

check out the info for installing the 12mm shock on www.rc10.com

mip top shaft vs avid top shaft?

i have heard that the mip one is the best one, also its exactly 4.0g and i have it i like it a lot reduce motor temp 10 deg

the avid one is 4 grams

well i remember reading somewhere on here that a couple of guys have gotten a few bent ones but at this point i think its your preference

What do you guys think about the MIP puck stytem?

well sorry for "over" posting but i also know about that haha. The sponsored guy at my track his buddy tested it for 2 months and said it was good an it should aprox remove 30g of weight from your car, however 90 bucks i think not, however if you got that kind of money go for it

People say the parts wear out a lot faster is it true, and what if you use it in a mod vehicle?

Not sure why people keep saying $90 for the Pucks system...MSRP maybe? AMain has it at $68...which still isn't cheap but it isn't $90 either.

It's not for mod racing...don't use it in a mod car, the mod car has plenty of power to spin up the drivetrain, the 17.5 being "power limited" gains a benefit from the lighter drivetrain.

I wonder if you HAVE to use their "grooved" thrust washers in the diff?
