This is the 10th scale my beloved pre wife gifted me for christmas.

Review

I like it a lot. It has proven so far to be durable wether it be -18 and in snow or +5 through mud and tall grass. It looks quite scale and the oil shocks result in quite nice and satisfying suspension movement. The engine provides a ton of torque for its very decent and soft tires, which becomes apparrent when you sit down and try to make this 5kg car climb up yourself. I am running it off a 5600mah 2s which gives it a top speed of a fast jog and battery life of around 2 hours in -10c weather through snow.

It is not a crawler but it can go up surprisingly steep terrain. It's main limiting factor are stock wheels that are too big - the wheels get stuck on the bumper, and upon trimming the bumper you'll find them getting stuck on the body at full flex(which is impressive)
The lights and lightbar can provide good light for driving in the dark but I replaced them with hellas to make the car look more era-approperiate. Lights are 3 stage- off, low beam, high beam and high with lightbar. The blinkers and brake lights work and IIRC it has reverse lights too. One thing that drove me nuts was the car would go into hazard light mode randomly. I assumed it meant some kind of error or low battery, but turned out turning left or right 3 times in a row turns on the hazards. I found the answer in some random indonesian fb video comment section.
I reccomend this car easily as your first 10th scale. It is solid. There are only a few things to bear in mind: Portal axles mean all 1.9" wheels won't fit, but its fine since stock tires and wheels are plenty good for trailing. The front bumper, however needs to be trimmed as It will catch the wheel and that is a tremendous amount of force your diffs have to deal with. Also the body locking mechanism SUCKS as it is a thumb screw that, we discovered, gets lost fast and easily. But it is no problem as you can leave the body unlocked and never know the difference, or 3d print a simple magnetic lock. I use this one. I also opened up my axles and added some lithium AEG gearbox grease to it. The tank turn is often critisized but I find it very useful when crawling - when adjusted properly(and it isn't from factory) it does indeed provide very tight turning radious. Not to mention it is mechanically NEAT!. To adjust it, remove rear wheels and tighten the caliper bolts until the disk is just a hair away from having light resistance. I find no need in replacing the steering servo with tank turn as 15kg is plenty to steer a 5kg vehicle that is used mainly as a trailing truck. I'd rather not do a 25 point turn than have a 25kg servo up front.
The Good:
  • Dirt cheap for what you get
  • Reliable*
  • Unique body that looks good
  • Capable of light crawling
  • Cheap spares off ali

Maintenance

After each drive I hose it down if it's dirty and apply a dab of universal oil to metal joints. Bearings at the wheel and u-joints get lithium grease. And I keep my lithium battery at around half-charge and discconnected. At least twice a year dissass

  • Detailing
  • The car has some scale detail: 3d printed gas can that is hand painted, aliexpress accessories affixed with belts and elastic hooks and a tiny mirror. Rear spare tire is just circular foam held in place on a 3d printed adapter
  • Hella lights
  • I designed and 3d printed my own adapter but this concrete file is unshareable cause I did it while learning freecad
  • cut bumper
  • Front bumper was cut to prevent tires from getting stuck on the car.
  • Magnetic body clamp
  • Since the screw is a pain to install and running with a loose body makes no difference I opted for a weaker but easier to use version.
  • 5600mah battery
  • After an hour of driving at -8 through snow it has around 40-50% charge.
  • Window seals around wheel arches
  • I have put D shaped window seals all around the inside of the car to prevent dirt being thrown into the interior.
  • TODO: strut bars
  • the car is quite heavy and strut bars are quite soft. I assume this factors into the tire rubbing.
