That's probably what I'll do then, is get a 6 pack and try the different ratios!

I've had a break through lol! Its kind of dumb but oh well, I was just messing around with the crawler while its apart and I noticed that when you turn the driveshaft it takes about 10 ( not 100% sure) turns for the actual wheels to turn on the axle....... now do most of you hard core guys change the gearing in your axles to make this 1 to 1??

It's more like 21 or 25 turns of the driveshaft, depending on two things, the spool's teeth count.

What's your thinking that you want 1 to 1?

Well, I don't know, I mean is that what most people do? Maybe not 1 to 1 though.....

Here's what I have right now sitting on the desk.

*Integy 35t brushed
*Tekin FXR, with BEC
*Lithium palmer battery
*losi night crawler
*And a bunch of other crap.

All this works together bc a buddy of mine had it on his crawler and then gave it to me and he had a 1 to 1 ratio on his axles which was a good crawler. That's how I got all this stuff! hahaha

Okay so with that being said, if use those three things and a stock 20t pinion or 15t and the axles being 1 to 1 or something close I should be able to get what I want without spending a lot of money right now in the beginning on an esc and motor...?

The most important factor in gearing is the motor to wheel ratio.
Crawlers are typically run at around 70:1, and that ratio is spread between pinion:spur, tranny and at the axles. (By comparison my drift car is 4.25:1, running the same motor...)
The result of running 1:1 at the axles is a monstrous torque twist. Having >20:1 at the axle means having as good as no torque twist at all!

If you mounted your buddy's tranny in your crawler the truck would be extremely slow even at full speed. The LNC tranny is optimised to deliver higher speeds (and less torque) on the drive shaft.

Axials and Bergs are usually closer to 40:1 total. From motor pinion to axle spool.

Okay, I just found a 14t pinion gear and I put it on with all that stuff and a 7.2 v NiCad battery it still doesn't have to wheel speed I want.... so adding the 2s lipo 7.4v and the 13.5t motor or a Holmes hobbies will give me that speed?

Are you looking to go faster than 5 miles an hour?

You'll want something like the Homes brushless 540 outrunner or maybe Tekin's ROC or something with a lot of kick and a 3 cell lipo. Maybe a Brood Axlebuster. Losi's worms eat power.

That was an Axial truck, yes. It's helhedded's. He's here on RCC. Can't really compare the two.

You'll also need to shave a few pounds off the weight if you want to do wheelies.

Exactly what you need to do depends on what you currently have.

You can start simple and get an idea what it's all about by reading up on why worm drive crawlers are slow and how to reduce the friction.

Do you still run the hardware shown here?

You will need, somewhat in order of importance:
* ~$400 to spend on the upgrades will be a good starter...
* Good ESC (MMP or Tekin RS) combined with a powerful BL motor. ($200+)
* 3S or 4S LiPo battery, 1,000mAh or less. ($20+)
* (Probably) Strengthened drive line parts to handle the power? ($?)
* Servo and battery plate for the front axle. (DIY?)
* Light weight CF wheels. ($100+)
* Lighter competition body. (~$25)
* CF chassis, to reduce weight. ($100+)
* Heavy knuckles and/or knuckle weights. To get COG where you want it. (~$100)

I have done some of this, but not gone crazy on power, no carbon fibre and no plate on the front axle. I'm very happy with the parts I have and now it's a matter of tuning the gearing (with the new motor), getting driving experience and trying out different suspension setups.

Why spending money on expensive CF rims? Buy some DE Racing Borrego front rims or TLR Buggy 22 front rims and do the SLW mod... saving around 80$!

Durability. Assuming your slow crawler has a top speed at about 50kph (which seems to be what Murli12 is after) the wheels will take quite a beating.
CF rims do provide the best performance/weight ratio.

Right now my crawler is heavy! Ive also got Sedona tires with weights in the front. Img gonna slowly get these upgrades and work on it.
