HI!... Well it's been a while but I started working on the "BIGWIG" again. Now I swapped out the TEKIN brushless motor and TEKIN ESC. They were junk. Had all kinds of problems with them. I swapped in a HobbyWing 6000KV brushless motor and 60 AMP ESC. Runs good on 2S lipo. Installed a 3S, 5000 mAh lipo this morning and it's crazy fast. Half throttle you punch it and it gets right up on the rear wheels. This is with the lowest setting on punch control. lol!
I started hearing a fun noise and pulled it in. I took the body off and put it on a stand so all 4 wheels were free wheeling. I hit the throttle and I realized the funny noise was the 4X4 driveshaft was getting the "SKIPPING ROPE" effect and arching so much that it was hitting the top of my LIPO battery. Glad I caught it when I did or it would of sliced through my LIPO and caused a good fire.
So I swapped out the differential out drives for some hex shaped ones. Can't remember what Tamiya RC vehicle they came from. lol! I slit them down the middle with a zip blade. I then took a old E-REVO steel center drive shaft and cut it in half and shortened it and re-welded it back together. I have a Kyosho 140MM driveshaft on order. It's 3 times as thick as the stock BIGWIG driveshaft. Hopefully that will cure the problem.

HI!... This is as far as I have gotten so far. I have since bought some TAMIYA "Dark Impact" after market T-BONE front/rear bumpers and will be modding them to fit on the "BIG WIG". This way I can lose the large aluminum stock bumper clone. Then I'll be tearing it down and going to get the chassis powder coated.

Wow, this is an impressive project. You must really want a bullet proof speed demon BigWig. Once you're done the only BigWig part will be the body.

Pretty cool undertaking.
