- Awesomatix A800FX Build by Max Machler -

During the build up of my A800FXC I took some photos which I wanted to share with you. I didn't follow exactly the steps of the manual. Every picture of the album has its own comments with some infos and tips.

The minimalistic but noble looking car kit box is the same as for all other known Awesomatix models.


First up i started with the front hubs and drive shafts. The kit is equipped with the AM06WL hubs and also the innovative IFJ drive-shaft system which is same as the A800X Evo kits.
Only difference at the front hubs are the AM14FX steering arms which are specially designed for the use with the all new linear steering of the A800FX.


The rear hub assembling is also similar to the A800X Evo with the only difference in the wheel hex. As the FX do not use any drive shafts in rear a new wheel hex (AT13FX) was needed.
SB3x4F flanged button head screws will hold all in position and secure the bearings plus hex in the wheel hub.


The thread to screw the wheel nut and the hex itself is now one single part. A bit unusual but genius


This is how the full assembled rear hub should look from inside. Make sure to tight the SB3x4F.


Next up I assembled the shocks.
The kit dampers are filled with 500cst oil which is a very good base setup for all conditions.
At this step you need to take care about following points:
- Do not overtight the SS3x3 set screws to secure SPR02X, otherwise you will destroy the thread inside AT41-2 damper vane.


After the wheel hubs and shocks, i took the chassis and added the P12X swaybar mounts as well as the AT21+P03 to mount the C04M1-LA suspension arms.


In front should be the C04M1+9.0 which can be recognized at the different outer shape.
The +9 arms have a more detailed shape there compared to the +8 arms.


At the rear end the C04M1+8.0 took place.
Please note here the different outer shape of the arms for identification.


A view from the lowerside of the chassis.
The rear end is very narrow and slim to offer the needed flex characteristics, as well to minimize chassis scrubbing.


The motormount and also the pulley are completely new designed for the FX.
All is well manufactured and the pulley is now full alloy including the pulley flange.
The motormount offer different flex options, same as all other known Awesomatix models.


The BANDO front belt need to be installed together with the AT120FX pulley. Otherwise you will be not able to get the belt over the pulley.


For the radical new FWD car design it was needed to place all weight as far as possible in front of the car. A normal bell crank steering would need to much space in total. This leaded to the super slim linear steering design.


TIP: Add a bit of grease/soap/oil in the holes of P49 before you screw the ballstuds.
The ST152 steering holders are made out of high grade steel to add more weight up front in the car. The whole system slides super free on the ST70 guide bars. The "free play" is impressive, as its close to not existing, which leads to very precise feedback on the track.


Make sure to place the belt under the steering at assembling. Otherwise you will run into trouble at later stages at building


Stunning view from top with the motormount and steering installed.


Front bulkheads and shock holders are same as from the A800X Evo.


I recommend to not tight the screws of AM88L/R fully at this stage ! Otherwise its possible you are not able to install the shocks later.


Spur gear change is super easy and fast. Only one single nut (AT55M) need to be removed and you can change the spur in less than 20 seconds. As the FX use the same internal drive train ratio like the A800 AWD, you are able to use you Stock class spur gears here as well.
In my case I installed a 100T 64DP AXON inc. TCS spur gear.


The single pcs. floating alloy servo mount is also a compatible part to the A800 AWD car range. Strong, reliable and perfect!


Close fit between motormount and servo mount
All to keep the left/right balance as best as possible.


Time to install the front shock units.


After the shock unit is in position all the screws can be tighten of AM88L/R. Otherwise its very easy to add tweak into the chassis which cause bad handling and performance at track.


At the rear end of this car are no real "bulkheads" are needed, as we do not have any drive train here.


Four AT157 uprights in combination with the C34 strut and the C105 rear bodyholder build the rear "bulkheads". Make sure to follow the instructions about the tightening sequence for the screws here to eliminate any tweak.
The AM08L-FX may remind some long time Awesomatix users on the A700 times.


A closer look from the back of the car. The conventional solution to have 10cm long vertical bodyposts which are wobbling all the time were not an option for us. The horizontal mounts offer a more solid body mounting which help to keep the hatchback bodyshells in position more accurate.


Installation of the rear shocks are very easy.


Not much to see at the rear end. But enough to be fast


Time to install the top decks!
This design offer different flex settings via ST019 top deck screws to match your driving style and track conditions.


Take car at the front C107 topdeck to install it with the correct side up. There is a recess area for the ST019 screw.


In rear the topdeck is fixed by the ball studs for the rear upper links. On the motormount are holes for two ST019 screws which offer different flex options. Both screws = stiff flex. More precise and stable rear end. Only one screw = more flex. More rotation and steering in corners.


Just beautiful with the top decks installed!


Swaybars are the same as in the A800X/Evo. Ballbearing operated for smooth and precise action.


Remind to use the small hole in P05 swaybar joint for 1.0 and 1.1 swaybar and the bigger hole for the 1.2mm swaybar only !


The full alloy case gear diff is the well proven version which is used long time in the A800 AWD already. Take your time at assembling with heavy silicon oils! I choosed 200.000cst as initial setup. After some track time on asphalt, i would recommend 100.000cst
Upper link holders are new designed for this car.
They are optimiced for the use with the C04M1-LA arms.


After the gear diff is installed, the whole drive train is finished. During the same size of both pulleys as used in the AWD cars, we are able to set the belt tension same easy and free as always. This leads to a free and efficient operation.


One of the "biggest work" is always the turnbuckles. BUT for this i have great tip for you.
A drop of ball bearing oil in every ballcup will make it A LOT easier. Also the future changes of the parameters will be more enjoyable with this tip ;-)


Take care at installing of the wheel hubs in the suspension arms to not overtight the screws in P04 arm hasp. The hubs need to move free by their own weight ! An important step which can influence the overall car handling a lot.
Nobody wants additional friction in the suspension!


Closer look to the rear end with full suspension installed.


Just stunning ! Beauty of production.


One of the most important features of the A800FX is the special designed bumper weight.


The P15FX foam bumper has a special recess area to fit ST265 inside.


ST265 bumper plate weight is ~65g.


With the possibility of adding another 5x ST110 10g weights the overall weight can be raised to ~110-115g. (depending on the tolerance of my cheap china scaled :-P)


Easy installing of the ST265 plate on the std. P14X bumper plate.


The full assembled bumper unit.
With the possibility of changing the weight inside the bumper its very easy to adjust the overall weight balance of the car which is the MAIN INFLUENCE at setup on a FWD car.


P15FX foam bumper is a bit bigger to support the FWD shells better without need of additional foam inside the bodyshell.
For some bodyshells it can be needed to cut the front bumper a bit!


The last step ! Installation of the bumper and rear bodyposts, battery mounts and antenna holder.


Remind, the battery should have some free play to not influence on the flex of the chassis!
Very important info!


You can cut the rear body posts easily to you needs after you fitted your bodyshell.
TIP: Place the inner bodyclips 3-4 holes more inside to allow the bodyshell some movement in case of "close racing" from the racer behind you.


FINISH ! The A800FXC build is done. Another high class build of a unique designed rc car from Awesomatix!
