No instructions pissed me off it was very anoying, and the mounting for the servo plate made absolutley no sense. There's the little aluminum cross brace which screws to the chassis side plates using the larger 4mm screws then the two holes in the middle of the brace which line up with the two steering posts are threaded for 3mm which clearly can't work...they have to be drilled out to allow the 4mm screws to drop through and screw right into the steering posts in order to brace the thing and to mount the servo plate. Now that that's done how does the genuis who designed this thing propose to brace the other end of the plate to keep the thing from flexing up and down (which I'm guessing was what mtbikertim was refering to). And the battery hold down is not gonna cut it...I will have to use a velcro strap of some sort. Other than those issues the kit is kick ass and is a good deal for the price.
the kit comes with a velcro strap, as for the lack of protection for the battery i made a case out of plexiglass for it. the servo mount is a little weird, the plate should be thick enough as to not flex though. but i suppose anything is possible with a big enough servo. ill update with pics of my battery thingy later
