Default loudest slowest crawler ever

This things belongs to 63comet. I'll let him give the full break down, but I'll list off what I know.

Sportsman Truck
Black widow chassis (I think)
Losi Worm Axles
MOA Conversion kit
Custom made pinion holders
4S Lipo
Brushless Motor

This is straight up, one of the best sportsman trucks I've seen. This thing works wonders.

Assumed gear reduction with spur, tranny, pinions, and axles is around 150. LOL

Different, but I don't see the point in loosing so much wheel speed

I can tell you it was NO disadvantage. This truck actually held lines better then other ones because tires weren't slipping on everything.

The slowing it down wasnt the point the point was changing pinions at the axle to change the front and rear wheel speed. To improve climbing and turning. The slowness is something we are trying to get rid of but the truck does stick like glue those boss claws do work at super slow speeds i was amazed.

I just got this truck running as the comp started, first time it was on the rocks. Something a few of us have wanted to try. I machined some holders to use my traxxas 4x4 slash axles and stubs. Turned down the stubs a little so i could mount the pinions on them. I have a 16 tooth pinion on the front and a 12 on the rear. On the axial tranny im running a 24 tooth pinion. For a motor a 5700 kv castle brushless. A mamba max esc and a 1350 4s lipo. And as you can see its still geared way too low!! With the moa conversion on the losi axles there is alot of room for adjustment so id like to try maybe a 24t on the front and an 18t on the rear . Wanted to overdrive the front while using shaft drive for sportsman. I have a huge range of gearing adjustment seperatly on front and rear axles. It still needs tuning but i liked how it crawled today.
