Retro Scaler Star Monster

I am currently building a retro Star Monster using Juggernaut II axles, a custom frame and a modded Clodbuster body.

In an attempt to make a extremely scale version I took some cues from the crawler guys. The frame rails are bent 1/2" square tubing resembling a Chevy truck frame. The real truck had a sub frame built from 4" x 4" square tube, very similar to the way the Hawk Chevy was built. I used 3/8" key stock for this portion.

Weight of the frame is a little heavy at just under 2 pounds, but I hope to mount everything else low in the chassis to counter the high center of gravity.

My question for everyone is on the transmission. I like the Axial Ridgecrest size and cost, there is also the Traxxas 3908, 3905, 3906... as well as others.

What should I choose?

This is going to be neat, I dont get how you guys bend the curves into the channel like that, but one day i'll figure it out

As for trans I would go axial, simply because you can build a bomb proof one for under $100 pretty easily.

Agree, on ebay hotracing has some built all metal under 100.00, they work well have a couple myself.

The extended out drive is so guys can run a MASSIVE spur. In the crawler/scale comp world it's all about volt up, gear down. Thats how they get maximum torque. You can easily use a regular output shaft version because you'll be using a smaller spur I imagine. Well, if you want any sort of wheel speed that is haha.

I dont know the gear ratio in a jugg axle, but the axial trans are geared pretty low. you'll probably end up mid-high 50's on the spur and mid - high teens on the pinion. If you use that included spur you're going to need a pretty darn big pinion to get anything above a brisk walking pace. This is all motor dependent of course. You could stuff in a high KV brushless and then end up using that big spur with a 12T pinion or something haha

same shafts just listed differently :)

Just have a 5mm drill bit handy and a dremel or sander to adjust the end as needed as sometimes you need to clearance it a bit so not to rub

Well all of the parts are here, next step is to get the dropped spring and shackle perches made. Then I will tackle the transmission cross member. I want to make it bolt in and have the mounting tabs for the front and rear traction bars.

I did get time to make my jack stands if you will. 3/4" particle board, top is notched to allow the axle screws to engage on it. Height is just high enough to allow the tires to clear by a 1/16".

awesome build will be watching for sure

I think the jugg2 gear ratio's 34:1 not sure if that's just the diffs or everything from motors to diffs...
