rear world conversion for rb5

[ongbenghui]

Hi,

Does anyone has a pic for rear "world" conversion for rb5 ?

I know that the arm is 2mm longer. However, does the overall width of the rear wheel increase by 4mm ? if so, will I get the same effect by having a wider rear hex.

Just curious.

no you won't have the same effect at all since the longer arms change the suspension geometry, there are also new rear hubs.

What difference do the longer arms make?

The main effect of the longer arms is, by the resulting geometry changes, to actually reduce the pressure at the contact patch of the tires as the car rolls through the corners. This in turn helps the rear end rotate progessively and consistently through the turns.

The reason Kyosho have gone longer arms on the rear of the RB5 and shorter on the ZX5-SP / FS is that the RB5 had such a locked in rear end that it was hard to get the back end to rotate at all without setting the car up generally loose where as the ZX5 had little rear end and would try and turn up it's own wing mounts!


I've tried lots of different combinations of rear arms & hubs and found that it is not really possible to improve (using off the shelf Kyosho parts) over where the cars have currently ended up.

It is a shame that the rear arms and hubs are not common between the two cars though as obviously that means you need to carry twice as many spares!

You coming over to the red corner the G'????? It's nice here!!!

Nah just interested Roger, though I don't have a 2wd car at the moment. Never had a go with an RB5, could be interested.

I just bought the UMW510-kit, and put it on the car. just curious about the rear hubs that was included "um519" what difference does they make compared to the kit-ones ?

I saw on the factorysupport on kyoshoamerica.com that the um519hubs are not listed if you want to buy your parts lose.

and........damn, the velvet rearshocks are....porn-ish

UM519 IS available ..... I have some and have had them ages!!!

They are a slightly different grade of plastic and only have the one lower mounting hole ..... basically they took a part that broke VERY rarely and mad sure it wouldn't break at all ... ever.

The Kyosho cars are built like brick-5h1t houses these days!!!
