The idea is great, but I didn't like how the shroud was designed in two ways.
1. Didn't cover the front on the chassis.
They have now improved that.
2. The second thing I didn't like about it:
It's attached to the underside of the chassis. Don't think that's durable. I know how my chassis look like underneath...
It might not be a big issue if you just drive on hard flat surface. But then you might not need a shroud, and it's not a rally if you are just running on asphalt...
Doesn't seem to be the smoothest way to attach it.
