It is not new, it is the product in 2019. I would say, the "mother" of modern TC as since then, all the brand all the chassis are going that direction ...
I wanted to start this project for long, and I got this car since it is released. But my mind stop me - I do not understand the modern TC setup and how it is supposed to be setup. I would not be able to enjoy the build, the tuning, and perhaps, waste the kit too.
Therefore, I picked up BD11 in 2023, spent lot of time to understand it, build slowly, drive and tune, and learn. Followed by BD12, which is similar, and then Xray X4 22' which I got the first batch during Covid time ... I even build a TA08R just in case I missed something from Tamiya, followed by the Infinity IF-14-2 with mid conversion kit.
I have drove BD11, BD12 and TA08R so far, and also learn how to the use ArrowMax 4D setup tool.
Now, I believe, I am ready for the MMX.
Read the manual, rear online material on building tips .... and I decided to buy the alloy chassis too - mine was MMX which comes with 2.2mm carbon graphite chassis.
Build started with steering kunckles, front spool, rear gear diff, bulkheads, motor mount, universals ...
Parts are small, and packaging is clear but no label or order, require to look for bags and bags to find the right parts or screws. But once you accept this, nothing really messy. Screws type are limited, shims type are limited, build is smooth indeed, and just very different in term of how it is constructed compared to other modern TC, eg, its universal joints, there is no use of grab screw at all, it has a different mechanism to secured all the parts together. Another example is the shocks, it is completely different than any other shocks I have built from 1/27 to 1/5.
Look at its lower arm and compared to BD11/12, A800 MMX arm are much thinner, there is no metal part to add on to it, a single plastic part was to add which serve 3 purposes - to connect the ball from steering kunckle, to connect the shock, to connect the anti-roll bar. I lost count how many plastic and metal parts I have to installed on the BD11/12 arms ....
Another interesting design - the gear diff - it was designed to have an exit hole for the diff oil to bleed out, like how we bleed traditional shock oil. and then use a simple mechanism to seal the exit and make a perfectly oil filled gear diff.
Nice and clear engineering.
I am not sure how this car run, even only building it, I think it is an fulfilling journey.
If you love RC and somehow you are an engineer, you would truely appreciate this kit.
There is no regret.
