SX-3 Chassis medium wheel base
2009 with again
extended equipment
The SX-3 Medium Chassis with a wheel base of 515 mm completes the Chassis Serie 4. The medium wheel base fits the new Porsche 997 GT3 body available with FG Modelsport as well as the Mini Cooper, which will be available in short time.
Therefore H.A.R.M. Racing seems to be the only manufacturer who offers a competition chassis in three different wheel bases.
Of course the Medium Chassis is also available in the Standard and Works-Edition version as well.
These pictures show the difference between the long and the medium wheel base. Beside a shorter chassis plate also shorter chassis reinforcements are needed.
The receiver battery is fixed laterally.
You find further detail pictures of the construction of the SX-3 Chassis Serie 4 within the different equipment packages of the long wheel base version.
As there are just some significant parts different also a conversion kit is available, ref: 1515906.
