Introduction
Chassis suspension (suspension) system is the general name of all force transfer devices between the frame and the axle or wheel. The main function of suspension is to transfer all forces and moments between the wheel and the body, such as supporting force, braking force and driving force, and ease the impact load transmitted to the body from uneven road surface, and attenuate the vibration caused by it Ensure the comfort of passengers, reduce the dynamic load of cargo and vehicle itself.

Although build quality seems ok, kit was completely missing crucial parts (springs nuts, bolts). Disappointed that I could not build the kit and wasted my money. I doubt the seller will send the required parts. Would not recommend this kit from this seller.

While the printed instructions included in the kit are vague, the website offers a very good tutorial and terrific instructions.Very impressive and performing tank chassis when fully built.The shock absorbing suspension is simple and should allow a load capacity of 5-7lbs and allow for sufficient articulated movement.

I must admit that I have not completed this project. Since I can add to the basic structure, I consider this be one of the challenges that I most crave in building these machines.

I can get over the damaged parts or the missing screws that I can locally source but this becomes completely useless when critical machines parts are omitted from the kit. Save your money and avoid this money pit.

Don't expect thorough instructions. I had to stop and think it through a couple times but I got the chassis assembled in about 2 hrs. It did not include the 2mm retainer screws needed to keep the wheels on the axle, so consider ordering a set (10 total). They'll need to have a wide head or washers. Other than the missing screws, I was pleasantly surprised that everything went together well.As far as durability, I think the frame is a bit on the flimsy side - I plan to add some bracing to keep the track frames rigid. The tracks are some kind of plastic/ABS and they are decently strong, although time will tell if they hold up, and they have zero traction on smooth floors. It is not fast at all but it has reasonable torque. The spring suspension is very firm - unless you have a heavy payload, it's going to be a bumpy ride.

Video is not of actual product and zero instructions on how the non drive idler wheel is installed. One motor kept shorting out internally and took out both of my 70A esc's. Also while disassembling I realized the sprocket on one side doesn't even line up! What a garbage cheap item

I put this together pretty easily. And am super satisfied with how it runs. It is a great project for price and if you're trying to work with PWM signals / a drivable device this is perfect.Cons: the directions could use some work but it wasn't too difficult to figure out some parts.Pros: when you're done you have sturdy tank body that is surprisingly agile.

Kit was missing two critical parts. I have been in contact with the seller who says that they will send parts 'soon.' Additionally 3 of the 10 of the axel shafts were over-bored causing the machine screws required to retain them to strip the threads. I was able to re-bore/re-thread the shafts and use larger screws to solve the problem. Overall I like the design and think it will meet my needs once I cure the manufacturing/packaging defects. Sell has been prompt to respond, but as of this time has not informed me that parts have been shipped. We will see.
