As a educational for combustion engine basics knowledge it’s perfect.
However model have some assembly flow’s.
Drive train including clutch efficiency and and engaging of it remains to be improved.
Cove box should have option for NiMh batteries as well, due to the fact that lithium doesn’t have luxury of long shelf life and model could sit on shelf untouched for year.
I misunderstood purpose of generator because wires was cut off.
Belts settings remained to be improved.
Optimal canopy for already cool car model be nice.
Make me think that’s the original idea was different.
Maybe tiny cool remote better than WiFi(just guessing)
On scale of ten I wold put rating nine overall it’s great and I enjoyed the assembly.
