Tips and descriptions from David’s father and mechanic Pierre Ronnefalk.

1. Servos

David are using KOs RSx Power servo for gas/brake and Response for steering.
On the picture you can se that he use KOs steel bushings (option) to the RSx to fix then hard to the servo plate.
Servo saver are also tighten as much as possible so the only flex are the plastic arm on the servosaver it self, and that´s the reason we cant use the new alu servo sever as i guess it will damage the servo with this configuration.

2. Front

As we use the alu caster it will be more power/flex on tha lower arm. One thing to make the arm stronger is to replace the lower hinge pin with “IS119-41” from the truggy to go thru the arm and locked by a nut.

Note that i dremel the lower shock pin flat on the upper side to easy know that i have turned the pin correct.

To prevent too much play on the ackerman i place a 8x10mm shim on the steel bushing before i put the bushing on the ackerman.

3. Middle

I have the fuel tubing on the same way Cody King have/had it. The holder for the Original fuel tube are from TLR.

We always use the ventilated brake disks IF415.

Normaly we have the transponder under the KO Switch, but at EC i putted it in where the standard switch are, just to make it possible to change it fast.

For pipe holder i use 3mm piano wire, and secure the pipe with a holder to the swaybar with the round part removed.

David always use the long white antenna that make it easy for me to find/see the car on the track fast.

Regarding stock vs front cab body we always have both to the race and rest them as different tracks uses different bodys.

For the rest it´s no special things. We use titanium screws on some places, and some other options are used on some cars, but not always.
One thing we try to use are the replacement chassi (hard) as we normal use the cars for long time we want to have the same feeling on the chassi all the time.
