First of all: the overall final (static) result is amazing, but…
It is impossible in my view to drive this via remote control: there is way too much drag on the “moving parts” to steer te car or move it. I finally got it to move, but this took me about 16 extra hours of tinkering, 3D-printing (hours not counted) and simplyfying.
Also at least one rare part was missing from the box.
The manual is a real mess : quite often just following a different assembly order can save you a LOT of annoyance and stress. Furthermore a lot of the drawings are quite small and despite having 2 big manuals to your disposal building the car remains difficult and annoying to build.

Très bon Technic mais quelques défauts à corriger et quelques pièces manquantes .manque une aile avant dans mon set....par contre deux fois l'autre !!
