Well, these next few posts are a bit overdue – my last post was in June, and the car has been built and raced 3 times since then. Still, I kept some photos from the chassis build and from assembling the car to be ‘race-ready’ so I’ll show you them and try to give a little information as to how it went together.
The first thing I did after stripping the car down, was to give all the plastic Tamiya chassis parts a really good clean. Coming from “grubby” Nitro racing, I always have some cleaning gum lying around. Cleaning gum is a fantastic product, it allows you to press the gum into all the nooks and crannies and quickly remove all the dirt and grease that builds up from racing. With this being a (fairly hard driven!) second-hand car, there was quite a lot of dirt and grime to get off the chassis.
Next up was to start building up the chass, part by part. I’ve built one or two Tamiya RC kits before, and the thing that I remember about them is that you shouldn’t over-tighten any screws when building the chassis. Because the parts are plastic, they bend if you over-tighten the screws, not only are you risking the possibility of stripping the screw thread, but you’re tweaking the chassis at the same time. So I took my time, and built it up slowly a piece at a time.
Chassis build about to start!
Chassis build under way!
Make sure you get the rear chassis parts the right way around for your chosen wheelbase - this one is MWB..
Make sure that the spur and idler gears are clean and free to rotate when installing them into the transmission housing
Added M-05 Ball Diff - This has since been replaced with a 3Racing Gear Diff (M06-06) using Fastrax #5000 silicone diff oil
Once the transmission is built join the two chassis halves together and screw together
Make sure that when you attach the lower wishbones, that they are able to swing freely. I also replaced all the ball-joints and ball cups/links to minimise slop in the suspension.
Front-end built up, the steering knuckles were not a standard M-05 fit so have now been replaced with official Tamiya parts
Chassis & Front-End Built - Rear end next!
The rear end went together very easily – one of the things about the Taimya M-05 is that being FWD, there is hardly any rear end to speak of – just something to hang the rear suspension components off and two axles sticking out of the rear hubs.
The principles I kept in mind whilst building the chassis were:
1) Don’t overtighten screws
2) Let all suspension and steering components swing and rotate freely with minimum slop.
3) Clean all the components before building
Next post is the Yeah Racing Aluminium Steering Rack for the Tamiya M-05.
