Oscar, are you going to build these topdecks in carbon?
I didn't pick the 3racing chassis due the 2 piece topdeck, but at the end it seems a better platfom than the xenon... nevertheless, your topdeck seems mean ....
@ Rampal:
First i will make the top and lower deck in epoxy ( glass epoxy composite )
that is cheap an stronger than carbon.
This project also managed to get the battery 4 mm closer to the center of the car.
When all parts fit , I will testdrive the car for a few weeks on an outside track.
When that works well there wil be a carbon version to save weight.
By the way, the topdeck will not fit the standard lower deck from 3 racing.
