Chengxin Wang's HG-P407 All Weather Cross Country Built-to-last Metal 4x4 Toyato Pickup

Small Factory

Running and driving chassis. With the taller shock towers, and higher arch leaf springs, the required shock length was 110mm. This length shock isn't my thing, so I went on the ebays and found these fabulous units. $15 for 4, so I got 8, and used 7. They are only aesthetic, no oil or springs were used inside. Wheels are RC4WD, which are aluminum, and have a wider front offset. This compensates for the different axle widths, and it make such a big difference. Tires are the same size and tread pattern as the Tamiya units, but are a much softer compound. These popped up on ebay about 12ish years ago, and then disappeared shortly afterwards. Really glad I got them. They have some proline foams inside, because without foams the rims would be on the ground.


Still have to paint the battery tray but it works a treat.


Similar to the steering, I just made up my own shifting link-bar with some rod ends and a link from the link collection.


Went for the best: the $18 'Zoskay' servo for the shiftings.


I was initially going to get an inexpensive hobbywing 1060, but the small price jump to the 1080 buys so many benefits I couldn't say no. With this unit, I can run the servos at 3S since the BEC supports it, as well as the servos. I also have the ability to program using the simple and sleek programming card that I already own. I have channel 4 tied to the dial switch on my fabulously advanced futaba 4PL, which I have the drag brake accessory wire tied into: Now I can drive it with freewheel, some brake, or if I decide to partake in some EXTREME (guitar wales in distance) crawling, I can not have it roll down a hill and crash into oblivion.



In case you were wondering why there was a missing shock on the front passengers side...




Why a 299 Low Profile servo? Because I prefer to keep a low profile.


With the additional lift, the OEM front drive shaft would not reach, so I found this metal one in the bag-o-shafts.


Angled the rear axle up a smidge.



I am happy to report that it does indeed function forward backward turn left turn right as advertised. I did not test the all weather fun or built-to-last-ness. I did drive it around the driveway though, and it shifts into all 3 gears properly. It runs smoothly, and is really fast with the included 20-tooth pinion (on 3S). I found a Tamiya 16-tooth pinion and installed that, which made driving it in high-2 less sketchy. I believe I will be able to fit a 14-tooth pinion in there, so I will try that in the future. Honestly, I see no reason to drive this in high-2 ever, as low-2 is more suitable.

Man, even if it had none of that function, that's a fantastic looking chassis!
Nice build!
It is a good looking truck just for shelf duty.

I feel like they have the high-2 gear just for bragging rights!
Pretty much: back in the 80's the electric motors were very limited, so multiple speeds would be necessary for a truck like this to drive at a 'normal' speed but also be able to climb a hill. Today, with brushless motors (and higher voltage batteries), multiple speed transmissions aren't. I think that the most important thing in a bruiser is the ability to switch from 2wd and 4wd.

Seeing as it's winter, the body will have to wait. I just quickly assembled it for pictures and shelf duty for a few months until warmer painting-friendly weather arrives.






Weirdly, the front body mounting hole was way off. I filled it, then moved it back. Then I decided it wasn't far back enough, filled that, and moved it back again.
