Tamiya gears are metric 48 pitch. You need to buy a metric 48 pitch gears standard 48 pitch won't work right.

"metric 48 pitch" is like saying metric inches. Metric gear pitch is expressed in module. The gears in the TT02, TT01, and Mini's are .6module. Smaller numbers mean smaller teeth. Module 0.6 is "close" to 48 pitch. Which sucks, becuase you ~can run them~ but it's ugly.

Robinson Racing makes .6 mod gears.

Metric 48 and .6 are the same thing I've heard them as both.

Gonna be painting my TT-02 Subaru Impreza body soon

How did you guys paint yours? Black on the underside? Clear windows? Black windows? Silver underlay?

I have no idea what to do

Had to grind away some material off the cover to make room for the longer shaft of the 550.
19 tooth tamiya pinion....and she's hot,super smooth.

What base colour are you going with?

If it's meant to be bright and metallic, back the base colour with silver. If it's a dark colour, back it with black, light colour; white or silver.

For the windows, you can leave them clear, or dust them with some Tamiya PS 'Smoke' for that tinted look.

The only company in the world that seems to use the term "metric 48 pitch" is Robinson Racing and frankly the term is an oxymoron. 0.6 module is the correct name and the gears can be easily found if you search for them using the correct name or "0.6 mod" for short.

Fun fact: 0.6mod is ~42.33DP and 48DP is ~0.53mod, just as 1cm is ~0.394" and 1" is 2.54cm
If someone sold you 'imperial' 42DP gears, they would indeed mesh properly with 0.6mod gears.

I’m going with the classic Subaru metallic blue

So I should do silver on the underside?

Yes, not to be confused with 48 pitch. Meshing a 48 pitch pinion with Metric 48 (Mod 0.6) spur will produce sounds your ears will not forgive you for :D

My primary concern with painting Subaru blue is matching the rear wing. Tamiya’s released TS-50 Mica Blue specifically for the Subaru WRC cars but that paint is for the styrene plastic parts, not polycarbonate.

The instructions call for PS-16 Metallic Blue but I think it ends up being too light or too green of a tint. I’ve used PS-59 Dark Metallic Blue with about a couple of coats, then finally backing it with silver. Let me look at my stash at home and I’ll know what I used. I tested the layers on spare polycarbonate to get the layers right. Use the wheel cutouts.

You can see in this photo it looks kinda greenish blue towards the front, but the rear fender where the light hits it is a deep metallic blue. The car is actually one uniform color, the light and shadows is what’s giving that effect.

So does PS-16 or PS-59 look better?

I like the one on the bottom, looks like original color. I just bought the Cusco Subaru kit that I would like to do like yours.

Hoyle33 04-22-2019 04:23 AM

I keep hearing people talk about how the Tamiya connectors aren’t made for 2S LiPo batteries and should be cut off and new connectors should be added

Is this easy to do? Should I just go ahead and replace the motor and ESC as well with new style connectors installed instead? Or is the stock brushed motor and ESC with Tamiya connectors fine to use until the motor inevitably fails?

Or am I just being a worry ward and keeping the Tamiya connectors with an adapter for 2S LiPo batteries will work just fine?
