Did I just buy an unnecessary part?

I don't know much about what a Torque Splitter is, but I won an auction for my Manta Ray. Not sure what it is for. Hehe...

I have bags of stuff…. “Oh that might work for xxx”. Lo and behold it doesn’t…

Dude, if I had a nickel for every part i bought that wasn't strictly necessary, I'd have a stack of nickels to the stratosphere.

Hehe... I'm sure you can make it work somehow....at least this particular part I think is a hopup for the Manta Ray/Df01. I might eventually use it for the Top Force...

it doesn't matter if you need it, as long as you got it for a good price!

It’s a racer’s hop up

I would like to believe so... upon searching it seems to be a discontinued part... it is a used part but complete. Got it for about the same price a bnew one if it can be found in stock...

I concur!     Gotta love the vanity favor.

I just bought a Blitzer Beetle partly because years ago I bought spare arms and gearbox parts.  Felt like if I had the parts, might as well get the kit!

dont sweat the small stuff, if you can afford it then dont worry. i got 6 sets of tires and rims for 1 TT02 and i have enough parts to start the build on my Manta when i get some time off. i dont know how fast it will go with 15T brushed motor but i occasionally look up TA-02 high speed gear set once in a while "out of fun"...

If you want a technical explanation what you've bought is a one way roller bearing for your centre drive shaft. When a 4wd car corners, due to the geometries of the paths the wheels follow, the front wheels want to turn faster than the rear wheels. However, at least one of them can't as they are mechanically linked to the rear wheels via the transmission (The front diff has to rotate at the same speed as the rear diff). The one way bearing allows the front diff, and therefore the front wheels,  to turn faster than the rears, improving the cornering by reducing understeer. The downside is that you will only get 2wd (rear) when you reverse. 

In my view, it's a worse technical solution than fitting a one way unit to replace the front differential. This is because the front diff will still allow loss of tractive force on the front end if one wheel comes off the ground. On other hand, fitting a one way unit instead of the front diff always supplies power to the remaining front wheel on the ground, should one front wheel lose traction. I had one fitted in my DF-02, and when cornering on tarmac the inner front wheel would lift off the ground, but the car still cornered well as the outer front wheel was still being driven.

Thank you. Yeah I can picture how it goes based on your explanation. Tbh, for a basher and low use rc, I don't really think this hop up is necessary/essential for me but I just thought I couldn't pass the opportunity given that the part appears to be discontinued already by Tamiya.

Realistically, I reckon 60-70%  of my purchases are unnecessary, and usually come about from a mix of bored browsing, reading build threads and thinking "oooh, that looks nice! or "I'd better get that now because it might become discontinued" or "I'm sure that'll come in handy for.....something"

And then I forget I bought the thing in the first place. Six months later I rediscover it and wonder whatever did i buy that for.

It's like Christmas morning every time I fumble through my parts box.
