Blue is most definitely more bling when it comes to this upgraded TT-01. Witha full package of alloy from the guys at Yeah Racing, Racer treats the Tamiya chassis to one hell of a makeover
Tamiya’s TT-01 is a 1:10 scale shaft-driven RC chassis featuring independent double wishbone suspension, with proven handling and performance. Since its release in 2003,Tamiya’s TT-01 has become a very popular entry-level chassis for on-road, drift and rally applications. The bathtub molded chassis combined with the central driveshaft makes it a durable four-wheel drive car for everyday surfaces, and the relatively light weight plastic chassis and mounting positions for the battery and motor gives it a low centre of gravity.
Yeah It’s Blue
Out of the box it’s an adequate introduction to the RC hobby but many owners wish to upgrade it’s potential soon after purchase. There’s been a wealth of models based on this chassis and a glut of after market upgrades from Tamiya’s own Hop Up Options series through to many specialist companies offering aluminium components in all colours and qualities which are available to further improve it’s performance.
Such a company specialising in this area is Yeah Racing. Based in Hong Kong, their ever-increasing range of conversion kits and option parts covers many manufacturers including of course Tamiya. We received their blue anodised set CK-TT01/E to add to Tamiya’s latest release the Toyota GT86. The full-size model features two-litre Boxer engine and has been produced in a joint collaboration with Subaru that has just been released into the market. So the package includes a comprehensive set of replacement parts and we recommend some care is taken familiarising the correct part applicable to the TT-01E as there’s some extra items that only fit the
original TT-01 model. An instruction manual is included which is very useful if retro fitting the parts or indeed assembling the chassis instead of using the Tamiya kit supplied parts.
First up are the prop shaft couplings and the very lightweight centre shaft and just these three parts alone transform the standard black look dramatically. Next come the rear wishbones and uprights which are simple to fit and extremely well made. Blue anodising is not everyone’s favourite (although most of even the TRF Option parts are this colour) so Yeah Racing offer a pink set as an alternative. Replacement dampers are supplied fully assembled and ready to fit and these alternative pistons offer even more fine-tuning and these are complimented by three spring options– hard, medium and soft. Certain parts are fixed with cap head screws rather than self-tapping so care must be taken to ensure they are not over-tightened. Other Tamiya hardware gets used throughout the build and occasionally some screws need longer versions particularly if retro fitting as the plastic has already been stressed on initial assembly. Some Tamiya TT-01E kits benefit from overseas bonus parts in certain countries and ball races are an important addition for smooth running and long life. The Toyota GT86 doesn’t – this kits bonus parts are a set of plated wheels! Fortunately in the Yeah conversion set, they have covered this point and include a fullest of bearings for the transmission and steering parts.
Faster and Smoother
The rotating mass of the standard kit drive train parts is quite high so it was interesting to compare with the conversion alloy parts. The alloy options were a tighter fit all round and with less weight, there will be some improvement in efficiency as well as in addition to the ‘bling’ look! Make sure you fit the front uprights the right way up else you will have to take them all apart to rectify – no, we got them right first time. All of the location points for axle pins and shafts are bushed and spacers make for a very close tolerance on the important areas. The C-clips retain them which is a big improvement over the standard self tapping pins which can pull out with repeated maintenance or repair.
Overall the combination of the latest Tamiya TT-01E and it’s finery of swanky blue alloy parts certainly makes an impressive ‘Shelf Queen’ which we are going to finish with the sleek Toyota GT86 body set. Finish off with electrics and radio and you’re nearly there. The kit includes an electronic speed controller (TEU 105BK) so just a reasonable steering servo, receiver and NiMH battery are required. Recent Tamiya saloons have had the facility to incorporate fashionable LED lighting units but are not compatible with this Toyota. An inner Lexan light bucket (molding)is supplied for both front and rear light clusters but LEDs just don’t fit! For racing you could opt to omit them and just use the decal on the outside of the body. Yes, we know it doesn’t look perfect scale but saves keep sticking the innards back on! Separately molded wing mirrors need to be finished in the body colour too.
Race Spec GT86
Real cars are already in competition use and I’m sure it wont be long before a JGTC version appears complete with oversized rear wing. The Toyota GT86 is quite a bland shape in road going form but of course most of Tamiya’s 1:10 bodies (and others) can be mated to theTT-01E chassis. We found a reasonable good looking touring car wing in the spares box to give the GT86 a moreracey look to complement the racing chassis parts! The conversion is manufactured by Yeah Racing but is sold and distributed by RC Mart (www.rcmart.com).
