Ive been out of the loop for a while, guess ill have to do some searching. Seems there is plenty of room to mount the esc behind the glue joint unless thats too far back.
I edited my previous post because going back and looking at the pics it seems to have plenty of room to mount the speedo. When I did mine I used a FT B4 carbon battery strap, cut it up and used that for the bracing along the side of the battery compartment and chassis, followed this up with a little bit of glue and some screws...came out pretty good. I didnt mean to come off harsh its just that i am a bit of a perfectionist and like to have my stuff looking its best. My chassis isnt as good as the one BK made but i think its pretty darn good (It is amazing what BK can make with a dremel and some carbon sheet). I am at work right now and will post a pic of it tomorrow morning / afternoon when i wake up.
