Professional TS300 Shock Absorption Robot Tank Chassis with Suspension Supporting Holder for Arduino Raspberry Pie, RC Tracked Model with 2pcs DC Encoder Motor for STEAM Teaching

It's alright, it's meh. Better have YouTube available and find a tutorial. The battery pack that's included (2 x 18650) is actually not enough to fully power the two 12V DC motors LOL. The Mac output fully charged is about 7V, if you run these motors with this setup it will result in two outcomes. #1 the most noticeable is the lack of power, the treads will spin but it's slower than a snail. #2 actually extended use of undervoltage will permanently damage the motors! They need to add at least a 3 x 18650 case.If you plan of using this with a robot arm it will be quite top heavy and due to the rounded curve of the treads it will tip over as soon as the arm reach for something. I am going to resolve this by 3D printing a front tread wheel stabilizer but it's besides the point. Just keep the shape in mind if you are looking to build up.I got this when it was on sell it looks to have gone up now but the quality did not change... Just the price. LolI would say do not buy this but I also would not recommend it to someone either... It's just meh.Good luck.

Not for the casual DIY'er. Great chassis if you have properly machined metric hardware laying around. Included hardware is way out of spec and will strip or not catch at all when tightened. Use proper size metric screws when assembling, provided screws are way undersize. Their M2 is like M1.8. Also several parts are missing, standoffs for wheels, screws, and lock nuts. You have to get creative to finish the build.Included motors are loud and inefficient. Had one short itself after ~6Hrs. No signs of overheating, just limited output. Use different motors, 25GA-370 work very well. I'm using the 300rpm model in the video.Shocks are useless unless you have several pounds of weight on chassis, but work if installed loosely. I suggest using lighter springs, or ones appropriate for your load.Using mini pix flight controller, AT10 radio, and R12DS receiver. Motor controllers are 10A Bustophedon.

Takes a tinkerer to assemble this. Instructions are useless due to tiny black and white images. End quality is good though. See video.Seller: feel free to use this video to help your customers assemble this thing.

The instructions for this chassis is garbage. With the parts provided the "Suspension" does not function as the part that is supposed to swivel presses against the frame and doesn't move at all. Additional washers are needed for the bearings in order to make space for the suspension actually work. I will post a follow up with pictures.
