Just a short questions off topic: as this will be my first brushless 2WD buggy i was wondering what turn it should be? I currently run a LRP Vector X12 7.5 turn motor in my DB01R and it feels pretty good on my hometrack. Should i go for the same on 2WD or do you normally go a little up or down in turn numbers? Sorry for being o.t.

[Fredrik Emilsson]

In that case, go for a 8.5 in your TRF201.

[muratti]

Thanks for your advice, Fredrik. Is there a special reason for going up in turns? The gearing of the 2WD in general?

[MRD]

I generally go 6.5t in 4wd and 8.5t in 2wd. The 8.5 can still be a beast tho, even with an old Vector x11 the car will wheely off the line if the slipper's too tight

By the looks of the Hopup list I'll be getting the imperial bearing axles and the motor plate straight away, and probably all the DB01/501 parts that will fit, like shock bushings and Ti Shock shafts. Not sure about the black shocks either, I think I'll get some HL ones

[muratti]

Thanks MRD, will surely buy the motor plate and imperial bearing axles straight away too.

Looks like front shock shafts may be different lengths by the new springs, unless they are just different rate to the 4wd!?

Putting together my order at the moment!!

Most likely different rates due to the very different weight distribution of 2WD...

its a metric car, keep it all metric

I wouldnt get imperial bearing axles unless b4 front rims would fit, which I doubt.

Thats kind of the point of releasing an imperial axel set, so b4 and Jconcepts wheels will fit. What did you think it would be for .

Same thing I was thinking a 8.5 in this car should be about right.
7.5 is still a tad too much motor in a 2wd.
I know people who run a 5.5 in a 2wd and it's overkill.

That is soooo up to the track you race at! On our outdoor track an 8.5 is a tad on the slow side...

heard nothing about b4 front rims fitting. The axles need to be the same width too for them to fit.

the axle set could be possibly cos imperial bearings are easier to purchase in the US for replacement.


personally, tamiya should have went hex's on the fronts, like the rb5's and CR's, heaps better in my opinion.

It says here: 54220 TRF201 Front Axle (For 3/16” x 3/8” Bearings)

And B4 Front wheel bearings are......... yep 3/16” x 3/8”

And as these axles are made to take B4 front wheel bearings Im pretty sure theyre gonna be the right width to take B4 front wheels.

The reason they picked that method is probably because there are less parts involved and the hub can be alot smaller as it doesn't have to accomodate the bearings, and with the option axles all the people that are swapping from a B4 can use all their wheels and tyres without having to buy all new fronts.

Its a very clever move by Tamiya .

Sure its a smart move if thats the way it works out, but it doesnt say it in the part description, which is all people are saying, this is a problem tamiya have, their parts descriptions are often very poor, at least on the kyosho, they have a proline axel conversion, which means theres no ambiguity, you are probably correct, but its an assumption you have made, theres nothing for sure that the axels are set up to make the front end width correct with b4 rims

So, what other reason would they make Imperial bearing axles available as an option?





None.

Pretty easy assumption to make, if you ask me.

I agree, its an assumption that can be made based on having imperial axels as an option, but i dont think the smugness of other posts was required

On a happy note, the Tamiya 2wd in the hands of Lee Martin at the first BRCA nationals on the weekend, good stuff!!

Hupo says otherwise :P

Clicky

Not sure whether you'd class the 2009 Euros track as slow though.
