Tonka Jeep On WPL B-1 Chassis

The banggood drive shafts and the stock pinion gear shafts don't like each other. These are the shafts that are splined and have to be filed down to accept the metal shafts. I should have done a better job putting a flat spot on them for the set screws. It will be getting a full drive-train upgrade over the next week or so.
 
I keep losing drive shafts and the low hanging transfer case gets stuck on a lot of stuff. This project is going back into the shop for a drive train swap.
 
Motor And Transmission Swap

I swapped in the new motor, planetary transmission, and transfer case. The Jeep is much slower now but the torque is noticeably better. I think this is a 370 motor but I am really not sure. If anybody knows for sure, please let me know.

The rear driveshaft is the stock length. The front driveshaft was shortened a lot. I am going to build an angled skid for the transfer case to allow it to slide over obstacles. I have one on the rear diff of my 1:1 rig and it works great. This case does sit quite a bit higher than my initial attempt.

The motor, indeed, looks like a 370, aka “400-type” Makes for easy upgrades. *ponders* Hmm..400-size BL outrunner in JJRC MAN Kat1... Got a few small outrunners laying about from my airboats..Get me a metal gearbox like Yours..... *shuffles off to workshop, softly, incoherently, mumbling to self*
 
Where did you get the transfercase?
TIA

It is from aliexpress.com

Sorry, wrong link. The planetary gearbox that came with this transfer case made the rig way too slow. I ended up buying a faster planetary gearbox off of amazon.

I only used the 400 RPM gearbox from the amazon purchase, I installed the motor that came with the transfer case.
