A few pics of the Tamiya TA05-R – Part II


Close up of the centre of the drivetrain. Switched from the Tamiya 0.4 module spur to a Kawada 76T 48dp spur – I’m told that the largest you can fit is a 78T. Pinion is RW Racing steel jobbie, these are well suited to the car as the design means that they can be put on the motor without having to loosen or remove it. Some other pinions need more messing about with the motor screws to get on. Otherwise everything is a nice snug fit. Aluminium bulkhead top is unique to the TA05-R and very “bling”!


Front suspension. Kit is supplied with “Milky Yellow” springs, I have gone to the standard Tamiya option springs (#53440 for the set), simply because they are easier to tell apart! The car also comes with arguably the nicest version of TRF shocks yet.


Underside of the chassis. One slight disappointment for me is that the moulded chassis is not as true and tweak-free as I have become accustomed to with woven plate carbon chassis. Also, the rounded edges make it a shade trickier to measure ride height. However, this is not really an issue when you run the car. At our track the extra flex is a benefit, generating grip to keep the car planted. Also the moulded chassis is dirt cheap to replace – UK price is about £10, whereas most carbon chassis go for £50 or more! I already picked up a spare after I messed up with the threadlock and ended up having to cut slots in a few screws – fortunately the original chassis was only slightly affected so it is staying on for the time being.


Rear suspension – car comes with the optional Lightweight suspension setup from some of the TB Evo and TRF cars, seems to work well! One of the things about Tamiya is that they offer so many different suspension parts that you can get totally confused about what the best setup is. To my mind if the car drives well that is 99% of the battle won, changing parts on a whim makes for a pretty costly hobby. My only criticism of the LW suspension is that the plastic rear hub mouldings are made of a slightly softer material than the arms, proabbly to absorb impacts, but there is a shade too much play in the wheel axle. A little 5mm shim helps but is not the perfect solution. Tamiya alloy hubs are available but are expensive and have less toe in so you would need to change setup to compensate.


Last pic for now is trying to get a view of the steering setup. Pretty tight fit and the high-torque servo saver needs a lot of careful trimming to get right. More annoying is that the servo case needs to have an ear cut off to fit the car, again take time over this to get it as low as possible without weakening the ear. I also fitted some thin sticky back foam on the chassis to give the servo a little bit more support.
