 Back at 2011 we decided to lunch a car and engine project - called “TX” - where the engine has an CNC machined crankcase and it is structural part of the car. The main idea behind this project was to make the engine as low positioned as possible to reduce the center of gravity of the car and to make the car 100% symmetrical.
The first test showed huge potential of this concept, by winning the 2011 European Championship by Martin Bayer. After the victory we decided to work more and more on this concept before we put it on the market, to be sure that everything was perfect. We decided not to use this concept in 2012 and 2013 at Big Races, where we run the T series cars (T12 and T13) instead of the Tx series car. But our development continued in the background and specially in the second half of 2014 and during 2015 we redesigned several time the engine and the chassis until it got its final shape. The 2015 European Championship was the last big test of the completely redesigned Beast engine and the Tx chassis, where it showed its potential against the best drivers, cars and engines all over the world in an sweltering heat (35+ degrees). The Tx chassis and the Beast engine proved their power during this event by making track record and winning the 2015 European Championship by Ales Bayer. The Beast engine was one of a few engine in the Austrian summer heat that had no problem with overheating and had no problem with fuel economy.

 

Features of the Tx chassis and the Beast engine 

 

 
Tx16-430-06

Perfect symmetricity of the car

 

The side part of the Beast crankcase are made of 7075-T6 aluminium and has same bottom mounting points as the left side engine bracket, to make the engine structural part of the car. All the bottom mounting holes of the Tx chassis are 100% symmetrical. The standard Zenoah engine has a mass-produced mold cast aluminum crankcase and its tolerances are high. Sometimes these slight tolerance issues generates bending, so owners have to re-tweak the chassis after mounting the engine.

The CNC machined 7075-T6 alloy crankcase is a way stiffer than a mold cast aluminum and provides symmetrical mounting points, which leads to an "easy to drive" chassis.

Engine fixing
 
You can fix the Beast engine at three points to the chassis with two screws at each point. All fixing points are adjustable to make your car totally tweak free. At the front fixing point are two adjustment screws with hexagon head. With this two hexagon head screws you can adjust the gap between the engine and the engine fixture. The chassis and the rear engine fixture has oval holes to let align the engine perfectly.

Lower center of gravity

 

The Beast engine sits 6mm lower on the Tx series chassis than the standard Zenoah engine on the T series chassis. This means the Tx car has lower center of gravity and this gives you advantages at fast direction changes and the car has less tendency of grip rolling at high grip conditions. Because of the low center of gravity you can use softer springs and anti roll bar setup because the car roll less. With the softer suspension you can use more the curbs and the car is easier to drive on bumpy tracks.

Tx16-430-45
Complete servo tray change

The complete servo tray can also dismounted easily by removing the middle and front top deck (all in all 5 screws and 2 nuts if the middle top deck used) (if the middle top deck was not used then only 3 or 5 screws), disconnecting the steering and throttle/brake linkages, unscrewing the 6pcs. fixing bolts of the servo tray (4 from top and 2 from bottom) and the servo tray is out.
 
Tx16-430-46
High quality servo arms
 
Our ultra-strong servo arms made of aluminum and they have perfect fit because of the small tightening screws. The brakes are pulled by a special double ball-joined linkage, that can slide in when throttle move is underway.
 
Tx16-430-54
Power Supply Tray
(New in 2016)
 
Our new 2016 version carbon fiber Power Supply tray is designed to support the Beast engine’s Ignition Coil and the battery on a single plate. The upper battery support plate is the holder of the transponder. This tray is mounted as close as possible to the center line of the car, next to chassis. The weight of the tray, the ignition coil and the battery balances the weight of the other side mounted exhaust.

Front wheel hubs
(New in 2016)
 
New 2016 version front wheel hubs with 4 different offset positions on the top. The back inside hole was the basic hole on the T15 and earlier cars. The holes are 6-6 mm offset from each other. The different offset has effect to the rear traction and the steering characteristic of the car.  The hubs are made of  CNC machined 7075-T6 alloy. They have high quality, small and low friction bearings. The front steering arm has 4 ackerman positions which allows you to find the best steering characteristic that fits to your driving style.

Front wishbone
(New in 2016)
 
New 2016 version of front wishbones with center axis ball anti-roll bar. We moved the front anti-roll bar in the centerline of the wishbone to reduce dynamic droop change during suspension movement. If the anti-roll bar mounted on the top of the wishbone (like on the T15 and many other brands car), during suspension movements left and right side droops are changing and making the car not the same in left and right hand corners. When the anti-roll bar mounted in center line of the wishbone (center of rotation) then the left and right side droops stay equal. The wishbone made of 7075-T6 alloy and has zero play Steel/Brass hybrid ball joints.

Rear wishbone
 
The rear wishbone made of 7075-T6 alloy and has zero play Steel/Brass hybrid ball joints. The rear roll-bar holder has a plastic ball insert to reduce vibration and to avoid breaking. This holder also allows you an easy and precise adjustment. The rear anti-roll bar mounted in center line of the wishbone (center of rotation) so the left and right side droops stay equal during suspension movements.

Front suspension geometry
 
The unique features of the RS5 cars are unlimited adjustability of the suspension geometry. We use spacers under and over the wishbone ball joints and with the height of them you can adjust the roll center of the car. You can change the spacers inside and outside of the front lower and upper wishbones to adjust the front roll center. We have roll center spacers from 2mm to 10mm height.
 
Tx16-430-26
Rear suspension geometry
(New in 2016)
 
New 2016 version rear shock tower and upper wishbone mount with oval plastic insert allows you to change the position of the rear upper wishbone up and down by twisting or changing them. We have two types of inserts and you can change the height of the rear upper wishbone by 1,5mm increments. You can adjust the rest of the suspension with the thickness of the spacers, they are under and above wishbone ball joints. You can change the spacers inside and outside of the rear lower wishbone and outside of the rear upper wishbones to adjust the rear roll center. We have roll center spacers from 2mm to 10mm height.

Tx16-430-42
Controled-Flex design
 
Our three pieces top deck design is the key part of our controlled-flex design and allows you easy access to the servos. The RS5 T-series touring cars are the only ones on the market which give you the possibility to adjust the car from a 100% stiff to a very flexible setup by opening different flex windows. The middle top deck should be used only when the car is adjusted to 100% stiff configuration. Remounting it, you have to unscrew three screws and two nuts. Without the middle top deck, each servo can be changed easily.

Brake master cylinder

 

Our bottom mounted brake master cylinders are also supports the servo plate. This setup minimalize the flexing between the servo > servo plate > brake cylinder, so it makes the barking as precise as possible. The push-rod arm of the cylinder is long and has high level arm ratio to make the brake-force and brake-balance adjustment more precise. The brake master cylinder mounted directly to the chassis to reduce the center of gravity.

Tx16-430-35

Brake calipers

 

Our Brake caliper has small piston to make the brake less drastically, to make the tires lock-up as late as possible at the barking zone to allow you to brake into the apex of the corner. A spring pushes the piston directly back to its original position, instead of pushing the brake pads and then the pistons. With this solution the brake deflate quicker. To reduce the bending of the outside pad we mount an alloy stiffener plate behind its back, fixed by three screws to increase the brake efficiency and avoid bending of the pads.

Tx16-430-36

Drivetrain gears

 

Hard coated fine teeth (module 1) steel gears for clutch bell, lay shaft and differential to make the drivetrain more efficient. Standard clutch gear is 35t (34 and 36 optional), lay shaft big gear 62t, standard lay shaft small gear has 24 teeth (23 and 25 optional) and 72t diff gear (possible to mount to any RS5, FG and SCS diffs).

Carbon Monocoque chassis

 

The RS5 cars are well known about the robust construction, as the German nickname “The Panzer” shows. Thanks for our unique Carbon-Alloy hybrid chassis concept we can make a robust car without having overweight or without the need to under dimension some parts of the car. Our actual Carbon Monocoque chassis is the result of long years development and research to find the optimal number and angle between the different carbon layers to make the chassis strong, durable and with a right amount of sideways torsion to support our unique controlled-flex concept.

Tx16-430-40

Front bumper

 

CNC machined two piece plastic front bumper. The bottom part is designed to protect the front end of the carbon chassis from a damage, the bumper loll under the line of the carbon chassis to protect it and it is also angled to allow lower front ride height.  The top part of the bumper will help to protect the car during an impact. With the new clips system remounting the foam during adjustment of the car is very easy.

Tx16-430-41

Big-Bore shock absorber

 

Our shock absorber has polished, hard coated shaft. Its main body, upper and bottom closing caps made of aluminum. The volume compensator membrane has reinforcement ribs. The Conical pistons are CNC machined from Derlin and has four holes as standard and two and three holes as optional.

 

-          New brake Calipers (same as the F14) to improve brake efficiency. The new caliper has smaller piston to bake the brake less drastically. With the new brake the tires lock-up later at the barking zone and allow You to brake in to the apex of the corner. On the new brake the spring push the piston directly instead of pushing the brake pads and then the pistons, with this solution the brake deflate quicker. To reduce the bending of the outside pad we mount an alloy stiffener plate mounted with 3 screws, to increase the brake efficiency.
