..They are the thorn in the Spurgear of the 'Dirt Lot Basher'.
When not racing on the nice, clean, pebble-free, clay based surface of an official raceway, keeping foreign objects from lodging themselves between the pinion and spur gear has proven to be a bit challenging. My initial versions of the 'Homemade Pebble Sheild'..

..worked fine on 'Black' (modified blue truck body).
'Red' (modified red propulse body), seems to be more of a 'pebble collector' and managed to defeat the sheild. Well, I wasn't about to put up with any of that nonsense..
This is my Half-Eight..(currently parked till I rebuild the central diff and make a chassis brace to stop it from twisting)
Some of you may remember it from an earlier thread of mine. It's a Kyosho Mini-Inferno/ST. When you pop the lid off you are left with what I call the 'base shroud'..
Pop that shroud off and you are left with the bare chassis and the Central Diff/Slipper Clutch sheild..
Pop that off and you reveal the Evil Central Diff/Slipper Clutch..
My idea for the pebble sheild derived from that inner sheild . But I have revisited this approach and thought about Kyosho's Shroud. They seem to not be concerned with heat since the batteries and the motor are enclosed in it. So I figured I would make something similar for 'Red'.
Here's Red..
Here is Red with the lid off revealing the new 'full shroud'.
Popping off the shroud you can see how I pieced together four corners of packaging. I assembled it on the chassis, cutting and trimming each piece and then taping them together to form the shroud on the vehicle.
It is a snug fit. The bottom edge tucks inside the chassis pan. It's a bit of a tussle to install but once it is on, it is on tight and requires no screws to hold it in place.
Red is no longer a pebble collector, thanks to my Half-Eight and Kyosho..
