Solid axles help

[arelee]

I have a thread started= DAVE'S BELLY TANKER BUILD, and I've run into a problem.

I will be building this1/8 scale as a rear wheel drive car. I want to use a solid axles in both front and rear. I will modify the front so it will be "free=wheeling". The rear axle will be connected directly to the motor, as is shown in the drawing provided by @LibertyMKiii . I picked-out a set of nice looking, aluminum axles from "RC 4WD" to buy, (I included photos on the thread), but I am afraid that they are for off-road use, and won't handle high speeds. I know zilch about gearing, and could really use some advice. Will you please tell me if the gearing in the axles I chose will handle a speed of 70 mph or more? If not, do you know of a solid rear axle that will?

Many thank's!

For the front I would look into a different solution for the correct look.

For the rear anything RC and solid axle will be designed as either a crawler (low power and speed) or it will be a scale desert Baja truck.

I believe the key will be looking at axles that are rated for 6s or 8s use so it will actually take the abuse of a powerful motor.
My #1 thought for low price and parts availability would be the Traxxas UDR. It appears they make a chrome plated axle for the UDR at a reasonable price.

Jenny's RC has axle shafts at a good price.
The rear diff goes for around 49 ish on eBay

The rear diff is the same ratio again as the Typhon 43/13 making it a 3.3 ratio.

Hey Liberty. Good to hear from you.

I looked at the Traxxis UDR Unlimited Desert Racer, Traxxis La Trax the Losi Super Baja Rey, and others. Since all are built for speed, I figured that they would work. However, I cannot find a complete, diff., diff case, axles etc... anywhere. Somebody must sell the whole package?

To build this car, using your design,(which is perfect), it seems that I will need to start with the axle units, and plan the rest of the project around them.

Thank's for the information Buddy

You may have to piece it together which wouldn't be too bad...

39.95​	TRA8540x	axle housing rear diff carier chrome plated
49.95​	TRA8576	Rear diff fully assebled and pinion plus bearings
27.47​	85076-4	Rear axle shafts (best deal was on Jenny's rc and you could sell the front shafts that come with the rears)
15?		axle shaft bearings

+ shipping
You may want to email a breaker like Jennys RC or there was a new one that joined this forum and ask them directly about getting a full rear axle.... Probably would save you some trouble!

Great, I'll try Jenny's RC, (I've heard of them, but never bought anything). If that doesn't pan-out, thank's for the parts list. That really helps!
