lutach,
is that MBX5T a custom fab job or some kit? looks good. 8s?! wow. the thing must fly. how is it to drive? i am building a new RC8T right now and custom fabricating the chassis. i have alum and cf and not sure which to use. i want to use the CF but some think it will not be strong enough. what are your thoughts? how has your mbx5t chassis held up? is it cf or alum? looks like cf under there.
