Default TA05 M Four

The TA05 chassis has been a perennial favorite of the 4WD R/C touring car scene. Tamiya's designers have now incorporated its proven components into a new, unique 1/12 scale R/C chassis design. This chassis combines the TA05's 2-belt driven 4WD drivetrain with a 210mm wheelbase (overall chassis length: 292mm) and has a carbon-fiber double deck layout. It also features an aluminum motor mount which holds the front midship motor and spur gear. The TA05 gearboxes are equipped with gear differential units (37T) and the suspension uses M-chassis components such as suspension arms, universal shafts, and aluminum dampers. Separate suspension mounts are used to enable easy suspension toe-angle adjustments. The steering setup features durable aluminum components for precise control. This chassis is designed for use with Item 55105 Tamiya LF Battery LF1100-6.6V Racing Pack (M-Size) and it will be compatible with new 1/12 scale R/C car bodies that are under development (existing M-Chassis bodies are also compatible).

Features:
  • M-chassis suspension arms and front uprights are used for smooth steering response.
  • Separate suspension mounts enable toe-angle adjustment.
  • Universal drive shafts are also incorporated.
  • TA05 gear differential units allow a range of diff settings.
  • Aluminum dampers are mounted to a durable 3mm thick carbon-fiber damper stay.
  • TA05 front oneway and direct coupling can also be installed.
  • Blue-anodized aluminum motor mount holds a compact type 380 motor.
  • 2-belt drivetrain utilizes an 18T center pulley and efficiently transmits the motor power to the front & rear wheels.
  • Carbon-fiber double deck layout includes a 2mm thick 2-piece upper and a 2.25mm thick lower deck.
  • Battery pack and R/C unit positions are interchangeable to enable different chassis weight distributions.

Separately Required Items

●2-channel R/C unit with ESC. 
●R6/AA/UM3 batteries for transmitter
●Body and Tires 
●Item 55105 Tamiya LF Battery LF1100-6.6V Racing Pack (M-Size) & compatible charger.

Item No:84255

I've been waiting for Tamiya to release a 4wd mini and now that they have, I'm severely disappointed.

1. Wheelbase is not adjustable so you can't run 225 mm M-Chassis bodies.

2. M chassis arms?? They're junk, For a kit that retails for $600 kit / $360.00 street price, they should have designed one piece arms that are strong and light weight, reversible to allow for both m chassis wheel bases as HPI did on the cup racer. Or allow the arms to be moved forward and back as on the TRF416.

3. 380 motor???? From the Picts I have seen, looks like that 380 is tightly seated in there, so a 540 is questionable. If that the case, you can't race this against the ABC Genetic, cup racer, or Atomic VM2. So it's a $600 kit strictly for Tamiya TCS races?*

4. Bizarre shape LiFe battery pack that's not being imported.*

Tamiya, you can do much better!

maybe it's possible to mount a short lipo like xcelorin type or maybe 1-cell lipo pack.

There are many 2c lipos you can buy that probably would work. It is not like you need a 5000 battery, probably could get by with a 1800 to 2200 mah.

The street price is pretty scary, looks like it will have many hopups.

Now, is this running in the mini class or the GT2 class. Now that is the million dollar question.

I downloaded the manual for this last night. There's a motor plate that attaches to the motor, which attaches to the centre bulhead. The bulkhead looks like it has enough room to fit a 540 can. I think the 380 and 540 front holes have the same distance, if that's the case, it greatly improves the potential for this chassis

meh, this car is useless outside TCS. They designed this with high-end parts, but using entry level power source.

I realize these are vastly heavier than a 1/12 pan car, even a 1/10 pan-car. But what type of performance would we see from a 1s lipo?

You'd have to get a really high kv 380 motor.

I've got Thunder Power 2s and 3s 1320mah 13C softcase batteries I used to use in some heli's. I have no idea how they would transfer over to an onroad mini, but it would be great to be able to use them again as I've gotten rid of all the heli's. Size wise they'd fit no problem, while I know the 3s might be overkill would the 2s packs provide enough amperage at only 17 or so amps max? Thanks, Joe
