NSR 997 chassiebilder och teknisk information

CHASSIS:

NSR introduces completely new high-tech chassis and new anglewinder motor support with some solutions for best performance on all kind of tracks:

The chassis is completely new, it is nylon made “flat” design of 1 to 1,5 mm. thickness for maximum grip when cornering whilst capable to withstand crashes.

The one piece front axle can move vertically and there are  4 x 4/40 screws for front axle ground clearance adjustments to suit any different track surface .

As innovative concept there is a “V” shaped drop arm 64 mm. long which by meaning of two screws can be fixed rigidly at a required height (from 0 to 4 mm. ground clearance with an M2 x 6mm. screw positioned in the forehead hole) to the main frame chassis or either be set for a certain free drop (with an M2 x 8/10 mm. screw in the other hole).  Further more you can install a spring (like the ones used for the chassis suspension system) to enforce the “drop” effect.

Anglewinder motor support is totally new! We have optimised all the fixed dimension so much to grant the possibility to produce narrower cars. The side screw pods are now closer to the centre and specifically are symmetric to guaranty the best car balance. 

The sideway movements it has also being reduced by different support profile.

New triangular design; motor support is  held in position to main chassis –according to our usual construction philosophy- by three screws (one in front and two at the side) which are only crossing it to screw into an independent ring. This allows the motor support to move independently from the chassis and in the desired amount (which can be set by simply unscrewing the screws from underneath).                                                                                                                         

The motor is of an anglewinder configuration now reduced from 19 to  15 degrees only, from the rear axle! This is a new record!

There are new standard plastic cups and new cups for suspension springs.

The  motor weight is now exactly “balanced” with  50% on both side of the chassis .

It means that performance is better than previous motor supports.

The chassis comes with a removable traction magnet, located just ahead of the motor; the neodymium magnet is round, 4mm high and 8mm diameter with 3 different mounting positions.

The guide is counter-sunk well inside the drop arm guide to allow desired ground clearance by the use of  thin spacers to be placed in between the guide itself and the drop arm.

Rear pillow block height allows the gear to protrude only 0.5mm under the chassis level thus leaving 1.5 mm. gear/track clearance.

PICK-UP GUIDE

The guide is similar to that of current offerings, but it is low-profile (only 1mm thickness); exclusive adjustable height using .005” , .010" or .020” new spacers, to cater for racing on all types of plastic tracks, as well as wooden tracks with raised, flush or recessed braid/copper tape to optimise the braids contact. The pivoting shaft is 8mm. high for a free vertical movement (12mm for rally version).

The brass connectors used to fix the wires to the guide are newly made, slightly bigger, chosen to guarantee a tough contact with our smallest thickness braids.

MOTOR

The motor for the Porsche 997 is the King EVO 21K, fully developed by triple World Champion Salvatore Noviello, made always by the same NSR philosophy: to realize high performance product without compromises!

King EVO 21K motor has 21400 RPM at 12Volts with an excellent torque value of 322 gr/cm.

The motor can is opened from both sides, it has cooling oval holes and the magnets are ceramics.
