2wd mid or rear motor

[slow coach]

As the title says whats the best set up for dirt mid motor or rear mounted motor, tracks not groomed or smooth its normally bumpy with a nice layer of fine dirt sitting on the top, if you can get through the dusty layer it is quite hard packed underneath, a few jumps nothing major and quite rough rutted all over.

Rear for sure

lipo as well obviously as this does make a difference to handling

For those sort of tracks rear all day long mate. That is the reason you won't see any of the "big global manufactures" (like kyosho, Tamiya, Associated etc.) making a mid motored 2wd any time soon. Those are the bread-and-butter tracks in the major markets (USA, Japan etc.) so that is what the cars are designed for.
In this part of the world (UK / northern Europe) where we race on surfaces like grass and astroturf the dynamics are different and normally the mid motor cars often have the upper hand for a given driver level .... why I have been doing a rain dance before every 2wd meeting this year (but probably not next)

[slow coach]

ok so we are looking at either

Kyosho RB5 SP or SP2 ??
Associated B4.1
Tamiya TRF201

out of these which are designed more with lipo in mind and wont need bits added to make the car work, or will any of them work fine as they arrive lipo or not.

out of interest heres the jargon on the X-Factory

The X – 6² is the most proven mid-motor buggy in the world. In 2009 the X - 6² won 9 different National Championships, and 2010 is continuing that tradition. Ellis Stafford won the U.K. National Championship in 2009 for the second year in a row and TQ’ed the European Championship. Think it's only in Europe? Mike Ciresi won the 2009 Michigan Off-Road Series with his X – 6² on some of the most blown-out outdoor ‘gas tracks', and Yuichi Ajishi finished 5th at the 2009 All-Japan Championship Race. X Factory’s buggies are winning races all over the world.

The concept of moving the motor inboard just makes sense. Tires can only offer so much traction, and with the motor hanging off the back of the chassis, there is a inherit pendulum effect in corners, causing the driver to dance on the edge of control waiting for the rear end to step out. With more concentrated mass, the X – 6 Squared eliminates the pendulum effect, allowing the car to carry more corner speed and drive much more predictably. The mid-motor design also handles bumps better and is more stable in the air. Simply put, it’s easier to drive fast. The X - 6² makes 2wd buggy racing fun again!

be good to get some input from the mid motor section hear what they think

If there's lots of grip then mid motor. You can drive harder. If the grip isn't up or its wet like roger said then definately rear motor. My cougar is the best 2wd I've had but quality is poor. The b4.1 and trf201 are both excellent buggys and probably the least hassle. Just need to carry your own spares with tamiya.

I have just switched to Cougar from B4 as I will only be racing indoors this winter. The problem with the rear motor cars is lack of steering in the fast tight sections, power on understeer and the pendulm effect when braking hard (rear trying to overtake the front).

My last regional meeting on Astro was pefect to show the place for Rear and MID motor cars, the track was wet in the morning and dried by the afternoon. In rounds 1 and 2 it was all about traction and the B4 was way faster, as the grip came up it was about steering and the Cougar took over.

I used to race at the Proline Dirt Arena on clay so similar to your surface and rear motor was the way to go for sure.

For me the B4 was a stunning car, very well made and great value. I'm already finding out just how fragile the Cougar is and the price of spares are double.

RB5 obviously!! Loads of steering AND rear end, ultimate compromise for rear motored car IMHO. Tamiya looks pretty good as well it has to be said.

Seriously, Nick Caro runs his with next to no weight in (Ghea front bulkhead and about 5g to balance electrics I think) and I will be doing the same.

What you really want is a mid motored car that with a few quick changes can be reversed to give the RB5's rear motored characteristics .... holy grail I'd say! Now if only there was such a car in development that might be available in the next month you would be sorted wouldn't you

Might be worth a PM mate

Oh dear roger what creation you hiding?

In all seriousness alec springer had his cr2 going very well on the dirt the trick seemed to be running very soft and with the hydradrive in it

Talk about a teaser!

PM sent

[alexb4]

for me its got to be the b4, most places stock spares and need very little add ons and easy to drive + strong car
