GTO-EVO "CF" chassis

Some cool new carbon fiber chassis from GTO-EVO soon. They will be available in various configurations including for rally applications and will be AWD, which is very chic these days in the slot car world!

The AWD chassis looks like it should be fast. I've contacted Angel to try and get further details about US release/distribution and price.

I noticed a few interesting things about the CF chassis:

1) Two belts are used, to equalize forces, and perhaps divide the load to avoid rubber band stretch and springback (energy storing and release).

2) One of the chassis has a gear drive front axle, with power carried by rubber bands to the rear axle; the other has a gear drive rear axle, with power tramsmitted by bands to the front. I wonder why?

3) There are tire tread-cleaning pads on one chassism, to clean the cocoa or dirt or snow off the tires. These are obviously rally chassis.

Hello to all! to use one or two strap is not used to balance forces, the election of one or two strap go in function, if you want much front traction two strap, or one strap light traction but, in the case of wrc 4x4 of photo nº the 5 and nº 6, are two strap by the necessity to both give traction to two back semiaxes in types, since the back axis, of these two types of chassis is of semiaxes, is not whole a rigid axis like in any car of slot, in the other two models photo nº 2 and 3 are wrc with the motor in angle, in these two chassis prime the good back traction in damage of the front traction, usually put a single strap, since by the other side of the chassis, it locates to us outside the lateral one of the car since it obstructs the mall pillow of the motor, in photo n º 4 in this case we spoke of a prepared group To 4x4, in this type of chassis and had that is a commercialized plastic chassis and modified adapted within carbon an artisan fiber frame, between both chassis, a point of basculacion among them exists, facilitating therefore the adaptation from the 4 wheels to grazing track in changes of and unevennesses, by to explain it of some way the chassis if we underneath raised it of the center, the back axis and the front axis the chassis by the point of basculacion simultaneously approaches in the direction of the track, bending commented, in the case of the photo nº 1, we spoke of a prepared group SK traction here 4x2, in this case also the chassis is a double chassis one within the other, but without front traction and indeed the sponges that restrain the wheels, act of cleaners in the cases of rally of flour and to kill a little the shock of the motor when restraining. Not to doubt in doing but consultations or questions to me of your doubts. Greetings and thank you very much. Angel.

I get it! Thanks for the explanation.

One belt with full axles transmits less torque than two belts with full axles.

With half axles at the rear, you need a belt on each side.

Hello! in the case of the photo nº 4, that the chassis tilts in two parts, until recently time, were used rubber of meetings of the hydraulic systems like strap, this rubber is of rubber, or also it was used rubbers of transmission of wallkman them, these rubbers with the dust and the operation caused brightness to them and to lose traction with the pulleys, the strap slips, aside from being very hard in its tension, last are used strap you throw with silicone thread, which they are those that you see in the other photo nº 2, this rubber thread we located it in fishing article stores, are them of several thicknesses, go by meters, so we must look for the thickness and the length to him that better works to us or that but we like, are very elastic, the tension is very smooth and even so the transmission of forces is very good. Of course to the thread being by meters, we must cut it and beat with cyano.
Greetings and thank you very much.
