I took a look at your other pics and since we're discussing brakes I thought I throw out my 2 cents. I see you are using a full size servo for both front and rear brakes and was wondering if you have considered using a hybrid configuration of both motor brakes and mechanical brakes.
I have installed a mini servo (such as the crt.5 servo) to only activate the rear mechanical brakes while utilizing minimal motor braking power for brake bias. I've found that using rear mech brakes along with ~10% to 15% motor brakes provides a very nice bias. Small steps in motor brake power is all you need to find the right amount of bias. This configuration also reduces the amount of power needed from a brake servo so you will not need such a large/heavy servo. The size and weight savings of this setup may be something to consider in the future.

thanks Star,
i have some carbon at the machine shop right now being CNC'd. i am making a carbon chassis for the RC8t, 8ight-T, and MBX5T with kickup. if the prototypes survive my severe testing i am going to produce them. my website is modifiedrc.com and will be up soon. these chassis' are going to be sick and i am talking with some highly-respected companies in hopes of being able to sell these as a complete conversion kit. my goal is to not compete with other companies out there but work with them and provide a means for everyone to be involved to make a little money but more importantly to just have fun and provide a kit that is not yet available to the 1/8 brushless customer. it will be more expensive than the normal conversion kits obviously due to the carbon fiber but i think there are a few people out there that this product will cater to. myself being one of them. if the venture doesnt work out i still get custom carbon 1/8 truggies for myself which is what this started out as anyway.
so as far as the brake thing that is a good idea. i will have to try the micro server. i actually have my esc set to 15% brakes with my current setup, to kind of act like down-shifting when i brake. i really like my setup but i do have my bias set more to rear so doing the rear/hybrid setup might work. just wondering though, do you have to use a bunch of spacers to get the micro server to be tall enough to be the right heighth for the center diff? i hate using spacers to achieve optimal setup. monster Mike told me about also making your own center diff top plate to extend out and mount the micro server in that. that is an option i guess. for now i will probably stick with what i have as that is how my chassis are being made. plus, the carbon chassis will save me more weight than switching to a micro server will. thanks for the tip though. i am sure i will try it out in the near future on another project or something.
