TF38 greetings the 90-120 degree version can, the 180 would be running into the endstops of the steering hubs K.

TF38 3mm or close to it, the axles are strong but they are not fully machined, hence the slight difference in holes and straightness

TF38 not using a conventional plug in, maybe by "hacking" and overwriting the memory chip, but i suggest looking at a benidini or dasmikro sound system in stead, they are programmable using a usb key and special connector.

TF38 these tires are slightly bigger in diameter then wpl or jjrc 1:16 truck tires and are wider the wheels take the hexagonal 6mm adapter the wheels would give more speed and more traction, they will also increase the load on the motor so be aware of this. if they fit a wltoys a959b i do not know as i do not have a wltoys a959b

TF38 no, and only a few places sell the cable set. you could use the wire set that comes with a wpl truck, but you still need to change the servo and some wiring.

TF38 yes it does, i suggest setting the gearbox servo up so its normally in high gear (fast drive) and switches to low gear (slow but torque) upon demand, if there is no 3rd channel then for rock crawling fixing it in low gear (torque) is best, this can be done with a simple servo, or even a rubber band. don't forget metal driveshafts, the extra torque in this gearbox will quickly turn standard plastic driveshafts into garbage..

TF38 label clearly states 24 volt (upper right corner)

TF38 single tap, decent quality for soft materials, don't even think about steel or other hard materials
