Only just seen this! Fantastic craftmanship & thinking outside the box! *big applause*
To me the A-C carbon tub shells are the coolest & most impressive pieces of RC components I've ever seen in my entire life. I just love my S2 and S44!
Yours looks to be of the same standard!
AND - you've thinked outside of the box making that totally "alien/organic" top brace! Never seen anything like that!
Made me think... why not try to mold the whole shell out of thin carbon fibre, and attaching it firmly to the chassis, making it a part of the main construction itself? Then painting some of it, leaving some nude carbon...
Would be like today's top skis and surfboards, where you can see parts of the internal carbon (or wooden) core
PORN!!!
