I chose a model with metal parts for reliability.
However, on the very first evening, the car broke down in three places - the lower deck broke in half, the upper deck broke in half, the rear wheel was torn off (the rear hub was broken).
Ordered from basic:
- new bottom deck (P2501)
- new top deck (P2502)
Ordered from tuning:
- nylon rear hub (RP2513)
- dural reinforcement plate on the bottom (DB-A2501)
- duralumin stiffening frame on the top deck (DB-A2502)
- aluminum rods adjustable in length (A2510)
- front and rear lights
It took about 3,000 for everything, while the cost of the machine itself was 3,900.
When I was dismantling the car, but I had to completely disassemble it in order to replace the lower deck, I paid attention to the symbolic amount of grease between the gears, differential, etc. In general, I bought Litol lubricant for 80 and lubricated everything additionally.
But now I'm happy as an elephant. Also, the headlights are turned on from the remote control (there is a button on the remote control).
By the way, I ordered adjustable aluminum rods due to the fact that initially the front wheels were not parallel, but slightly at a degree to each other, and this cannot be fixed in any way, since the plastic rods are unregulated. Actually, just to align the wheels, I bought new traction, but this is not at all a mandatory purchase, you can live without it, just like without headlights.
