pmis's trx4 build

[pourMoneyIntoSea]

hello everyone. i'm new here. just bought a trx4 kit. still in progress of building. let's start



the packing is convenient. you poured everything out in a bag for a part and left nothing after the completion of that part



i turned the bearing by hand and found them quite viscous



the inside of the gearbox



the shift mechanism



installed and greased



the outputs (to the front and rear axles)



the slipper. i didn't follow the instruction in manual as i thought it would make the slipper too tight



now for the shift servo. traxxas labelled each servo



gear box part completed



diffs, exploded view



diffs gears



diffs completed



rear axle



as you know the diffs can toggle lock/unlock mode. this is the locked mode



this is the unlocked mode



the portal part, exploded view



portal part finished



rear axle completed



now for the front axle. similar to the rear one



the (pseudo) cv joint, exploded view



with one of them built, for comparison



front axle finished



now these parts completed



the main frames of the chassis



building the chassis



the frames, inner fenders and cross members assembled



to be continued

Fantastic post! As someone who bought the RTR the quality build pics are appreciated. I’m sure mine will need servicing in the not too distant future and these give great insight. :-)

let's continue. time for electronics. motor and gearbox first



it is necessary for the receiver to stay horizontal otherwise the gyro inside would not function properly



the diffs locking servos



all electronics installed. spaghetti near receiver would be hidden later



traxxas did a great job in designing the radio box which effectively organize the wires



it's neat and tidy now



you can flip the battery tray cover to adape different thicknesses



i found it impossible to insert the battery tray into its position unless i remove the LR and RR wire mounts first. the manual didn't mention that



electronics part finished



now the time for shocks



the packing of electronics is a good place for the shocks to wait for bubbles releasing



shocks finished



shocks and linkages on front axle



front axle installed



shocks and linkages on rear axle



rear axle installed



it's disappointing that propeller shafts are made of plastic



one of them assembled, for comparison



it is necessary to align the pins otherwise the universal joints would introduce fluctuation



no need to use thread lock during the whole building process. traxxas added thread-locking material on some of the screws



chassis basically finished



traxxas lipo fits the tray certainly. i like the traxxas plug which integrates with its parallel charging wire



wheels and rims are ready



building process halts here as the body, proline 1985 hilux which was ordered in ebay, is not yet arrived. to be continue
