Limitless The Budget Limitless Drag Build

[RedondoBeachRC]

This is a drag build I quickly built using some spare parts.

Includes:
- Used Limitless Roller
- Stock Diffs (3.308 or 43/13)
- 46t Infraction Diff (1 mill diff fluid... I think?)
- Spektrum 2050kv motor w/ 25t pinion
- MMX8S ESC
- CHNL 90C 6000mAh gplus 4S LiPo
- Radiolink RC6GS v2 w/ R7FG receiver
- Yokomo Drify Gyro V4
- ProteK 130T servo @ 7.5v BEC
- BSR foam wheels (Pink)

Unfortunately, after a couple of using some prep (corn syrup based sticky goop) for traction I ran into some diff issues. I forgot to shim them up. Rookie mistake. Especially when using prep on foam wheels your diffs need to be solid, because you'll be putting a ton of load through it.

Impressive CC logs.
Work your gearing now for PB's.
Keep an eye on your G's for Dragging

I finally pulled outta limitless for some drag hits.132’
Stock gearing on bar pink foams.
My PB was 2.1s @ 67+mph
Today I tried some of my sticky sauce I made.
1st pass was 1.9 @ 72 mph.
Someone above mentioned something about shimming your differential if using prep.
Can anyone elaborate on this.
I’m a total newb to this stuff.
Thanks

My diffs had too much play in them. So it ended up just grinding through gears. Shimming it allows you get it a bit tighter for a better mesh.
