We've finished some simple mods to make the dnano
much more fun for kids and non-racers. The Mario Kart below is a blast to drive.
Some notes on what was done:
1) The bumper system works great; the cars bounce off the rails and slide around the track very easily without getting hung up or needing reverse. The bumper is very flexible PVC sheet that is cut to shape and flexes on impact. Figure 8 tracks and "bumper cars" would also be possible with this type of bumper wrapping the entire car.
2) the two red objects outboard the sides are 1/2 OZ. weights that compensate (somewhat) for Mario's big head being so high up. The extra weight really settles the car and slows it a down (both great for kids).
3) In the end, we have Kyosho's initial great quality, extreme durability from the bumper system and still enough performance to make it a blast. I'm impressed on how well this all works.
4) The Mario Kart body comes from 1/43 Carerra slot car. It's simply dremeled out and velcroed to the top. I hope to add slightly larger wheels to make it look more like a mario kart. Donor chassis is the shortest wheelbase Porsche.
