Hoyle, Tamiya connectors are not "tamiya". They're a locking 2 pin molex connector that's only good for something like 20amps.

I wonder why people say "lipo" as I melted tamiya connectors on a 7.2v 1500mah pack.

You don't HAVE to replace anything. Even melted, while inconvenient, it wasn't a safety issue. you'll just see much better acceleration, and some higher top speed with good connectors.

Well I’d rather not melt anything.

What do you suggest? Can I just chop those “Tamiya” connectors off and solder new style connectors on and solve that problem?

Deans plugs is what we all used to use back in the day. They are very good and can handle lots of power. Soldering wires on tabs requires shrink tube.

A good more modern alternative are the HXT .. they have piece that covers the tabs so you don’t need to use shrink tube.

these two are best, especially if you’re new to hobby.

For racing we use bullet plugs straight into battery. Issue there is you can reverse polarity and fry ESC. Work around is to make one wire shorter so it can’t reach the wrong terminal. Issue here still can be that some batteries have + on left and - on right others vice versa.

stick with the connectors lol :D

I use Deans, when I need connectors. The asian companies call them "T-Connectors." But the Quadcopter people use XT60 and XT30. they're good choices too. A lot of your gear will have XT60 connectors on them too.

I have paint pens. I paint the positive side of my batteries, top and bottom, with red paint. I also put red shrink tube on the positive connection of my ESC. It's hard to screw it up when you have the colors screaming at you like that. Short versus long isn't good enough for me ;-)

Are the set screws on 64 pitch pinion gears usually 1.5 mm or 1/16"?

Depends on the vendor. Robinson racing tends to do 1/16, because their setscrews are 4-40. Other companies, tend to be 1.5mm, becuase they're using m3.

i paint the + terminal red and use red shrink tube as well.. yet still managed when I was in a rush to make a heat. So now I make one wire shorter. Also new batteries have terminals that go through to other side which makes it easier to have +/- where you want it by flipping it over

I swapped mine to XT60, because that's what my charger was fitted with. Oh and the standard Tamiya connector was junk. I could tell just by looking at it.

proliteandsc 04-22-2019 06:16 PM
Had a few Dean connecters fail on me. Go with xt60 if you can't plug it directly into battery. Definitely get rid of that Tamiya plug.

I finally received my TT-02 Subaru Impreza Kit, and realized it doesn’t come with an ESC. I saw a few unboxing videos and people had an ESC included, so it was a definite bummer finding out mine didn’t come with one.

The sellers online advertised the ESC being included, but the box says right on it that the ESC is not included. I complained to Tamiya and they said that what the box says is king. Stupid but whatever.

With that being said, what ESC should I buy? Is the Tamiya the only one that will work with this kit? It would be nice to buy an ESC without the undesirable “Tamiya” battery connectors.

Most ESCs will have no plug for the battery, just wires that you'll need to strip and solder a plug to.

There are no restrictions to what ESC you want to use. Entry level to high amp racing ESC, brushed or brushless, depends on what you want.

This is also a good option

I hear you can load the HobbyWing software on it

Does anybody know what tires came with the TT02-R kit? I am trying to figure out if it is an A, B or C.

Thanks
