	Take these parts.
	According to the manual we have to mount the servos without rubber grommets directly to the radio tray. If you like to mount your expensive servo's this way use the black plastic parts the 3x15 mm counter sunk screws with the blue aluminum countersunk washers. The black plastic servo mounting blocks are factory drilled with 2.8 mm holes to accept 3 mm screws only. It would have been nice if the kit has also 8 extra black plastic servo mounting blocks with 1.5 mm holes drilled!
	This is how the manual suggests to mount the servo. We will go an other way to save our expensive servo from unnecessary vibrations.
	Take the rubber mounting grommets that come with every servo! If you do not have them any more go to the hobby shop and buy the original ones that come with the brand and type of servo you are going to use. Every servo brand has different rubber grommet and bronze bushing dimensions!
	Place the bronze bushings that come with the servo from the bottom up through the rubber grommets.
	Cut from a plastic tree a scrap part of plastic. If it flat it is easier to drill holes.
	Cut a piece of plastic that is a little wider as the servo mountings ears. Drill two holes of 1.5 mm according to the distance of the servo mounting ears.
	Place the servo and use the original servo screws that comes with the servo. They are mostly 2 or 2.5 mm self tapping screws. Tight the screws with normal force. The bronze bushings will prevent over tighten of these screws and the squeezing of the rubber grommets..
	Here you see the simple new servo mounting plastic with the smaller original servo mounting screws used.
	Due to the bronze bushings the servo rubber grommets can not be over tighten and so the rubber grommets can absorb the vibrations of the car and save our expensive >100 Euro servo's.
	Here both servo's seen from the bottom.
	Mount the steering servo and throttle servo as the picture shows.
	Place the four bleu aluminum radio posts.
	Use 3x6 mm round head screws at the red marked spots and use some medium strength thread lock.
	Mount the transponder holder with 3x10 mm round head self tapping screws at the red marled spots.
	Open the radio box and remove the receiver battery and receiver temporarly.
	Slide the servo leads and in my case also an extra battery connector wire trough the wire holes of the radio box.
	Place the radio tray at its mounting position. Pull the servo leads as much as possible through into the radio box. Exception for the receiver connector wire I use. Put back the receiver battery.
	Secure the radio tray at the red marked spot with 3x15 mm round head self tapping screws.
	Now connect the servo and receiver battery leads in the right spot of the receiver. If you do not know where to put them read the manual that comes with the radio system.
	Fit the receiver in the radio box and put all wires on top of it. Close the radio box of the receiver part.
	Put on top of the receiver battery an extra layer of foam to prevent it from moving in the radio box.
	Close both boxes and replace the small body clips to secure the radio box covers.
	Fit at the red marked spots 3x10 mm counter sunk screws using some medium strength thread lock.
	The car with the radio tray installed.
	Ashame that a company like KYOSHO suggests to mount the servo's directly to the radio tray without the use of rubber grommets and or bushings. Also 4 extra servo mounting blocks with smaller holes should be standard in every model car so the original servo mounting grommets, bushings and screws can be used.
