Lipo chassis.....why not?

I'm working on a new design lipo spec chassis.
The project is based on a symmetrical drawing to alow same stiffnes on both side......more details very soon.....stay tuned:




Different Materials lipo holder for better balance Left-Right




For better balancing weights left/right side and front /rear i'm thinking to adopt a modulae brass lipo brackets:


Balncing test made using 3Dsmax Reactor :
45g lipo rear bracket and 12g on front seems to be a good starting point to have a nice balance.



Final revision: the rear lipo bracket could take some fixed weights to alow a fully , simple, balancing method....now the cahssis has 4 additional holes on the both longitudinal and crossing axes to make fine balancing adjustments.
Soon avaible at Fibre Lyte Composites..
