Chassis rail made by something like aluminium or alloy in CNC cutting then went to anodising.

Those pictures could be misleading? See the video on YouTube.. I think they are optional parts for future upgrades??

Looks like slightly better thought out than average chinesium. Axle shafts are questionable at best. I'd bet they break easily just looking at the design and have terrible angle.

Chassis looks nicer than most coming from that segment but the geometry still sucks. Again, better than average but that don't mean good.

Axles smell like traxxas photocopies from here but the toner is low so the resolution is off a bit. They did "borrow" the knuckle design from whichever chinese company that came up with it. I'd guess they're affiliated on some level.


Doesn't look like the worst rig ever but I'm guessing it'll be expensive for what it is. Like a cross rc but less suck.

Dual triangulated 4 link AND a track bar? Easily solved, but WTF? I do like the c-hub/knuckle configuration though, much like the GRC parts.

I questioned the 4 link with pan hard myself lol. Then got me to thinkin... Wonder how well a 3 link/pan hard setup would work on the rear vs a regular 4 link? Anybody tryed it?

LOL Ryan I would say heartily the Chinese should hire you as a chief engineer

Agreed with you here. That is the most weird design I have ever seen.

If I ever had a chance, I will certainly ask them Why??

In the real world, Land Cruiser rear suspension with 4 links + a panhard bar design.

Parallel 4 link requires a panhard bar. Single or dual triangulated 4 links do not require a panhard bar. Mixing the two makes for a suspension that binds.

Having bearings on the diff-lock actuators seems a bit like overkill and what is going on with the shock absorber style steering servo saver? The motor mount looks okay and separating the screws holding the motor from those used to adjust the mesh looks like a good idea. Battery tray at the rear isn't so good.

In the picture of the gears I'm having trouble working out what four of the six bevel gears shown above the diff spider gears are for. Looks like the center two are separate diff pinions but the other four?

Steering angles look okay if the picture is correct and approach angle looks good. I actually like the idea of aluminum frame rails, I've repainted my TRX-4 frame rails twice as my best rocks are by a beach and my second best has a stream running through the middle.

If decent quality materials are used this might be worth more than just a look but I would be using a normal drag link and changing out the steering servo.
