Hitec replacements for stock km.

[Johnston.jer]

What mods need to be done to install hitec servos in my new km baja? Do I need to buy a hpi stock radio box to use these? They are pretty cheap. Would consider it if there are heavy mods needed to the km box.

only mod i had to do was for front steering servo, i used the 5755 servo, and went with a PA mount and servo mount tab clamps, all got from DDM

Lol, yeah I know but with so many options out there I just want to make sure I order the right stuff. I hate buying things that don't work.

a reference pic for you I am using the same servo and clamps on my KM as well they went on after drilling out the holes slightly and grinding off the nubs, they have held up to some heavy abuse..

yah i knew you could do the drill out thing and grind nubs off deal, but for me, i went with the metal bracket over the stock plastic cuz i knew the servo was gonna be a bit more torquey than stocker. i wanted the extra strength, and other than drilling out the radio boxes front servo brace mount holes to run a larger provided bolt into the pa brace, there wasnt anything else i had to do. the clamps worked perfect, the servo mounted perfect. only issue i discovered tho, was if pa mount is placed as they say too, it puts the servo arm off to one side a lil, enough that the original geometry setup would not let steering work well on one side. fix was to flip the pa brace around opposite of what it says, wide part of pa brace on other side, with servo mounted in correctly. this put the servo arm only a miniscule amount off from original position. and then worked perfect. one other thing i will tell ya too on this servo setup, make sure after you turn everything on for first time, do not turn the steering at all, until you go in radio and set the side to side sweep less than the 100% something like 75% on each side, then work it out lil at a time till its just at full left or right turn. if you don't, it will blow the servo. i made that mistake, and blew the first one. and hitec sent me a new one.
