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)

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.
