My turn :
1. Easy access to diff , and the differential units are easy to rebuild. ***
2. Using less screws design. Preferably populated by 4mm screws and 3mm screws with 2.5mm hex.
3. Strong, straight forward and easy access plastic parts design.
4. Easy to build and rebuild design car ( therefore the number of steps to build the car become less )
5. High quality plastic and metal parts.
6. 4mm shock shafts and 16mm big bores shocks.
That's it !!! I hope Mugen Seiki, Kyosho, Xray, O'donnell, Traxxas, Hobao, etc. are reading this.
*** Example of stupid design : I hate the pin and the little grub screw on Hyper8's gear diff housing unit. In order to replace the bearings, I have to open the grub screw, slide the pin out, and pull out the outdrive cup ?? .... dammit !!
