Awesomatix A700 Presentation

The AWESOMATIX A700

I had the opportunity through the kind gesture of the designer and overall creator of this car , Mr. Oleg Babich, to receive a kit and make a photo presentation.

Through the positive feedback of the current owners and some impressive results by privateer racers at big events such as the famous European Touring car Series, I was aware that Οleg was on to something good and the kit should be impressive.

Nothing had prepared me for what I experienced during the assembly of this kit.

Viewing Tip: Some photos are much larger in size so you can enjoy in HD. Right click and open in a new tab or new window.
1. Front and rear wheel hubs
The housing is made of aluminum. The finish is great and the fit is spot on. I am very impressed by the choice of anodized color on all aluminum parts, and Oleg's attention to detail went as far as providing some beautiful high quality dark shiny black fasteners.



2. Axles
In front is a double joint axle and at the rear a more standard axle. By standard I am referring to the concept because the actual design is again unique, getting rid of any set screws which may come off during racing and also 'bind' the action of the axle. The design consists of some extremely small parts, all with the goal to minimize rotating mass. The risk when making such small parts is the dimensional tolerances. They have to be absolutely perfect and this is exactly how they are, perfect! Once assembled the front axles with the double joint have the smoothest action I've ever seen. The rear axles are a bit tight, but this will later disappear once installed on the aluminum wheel hubs and are tightened against the wheel.





3. Suspension Arms.
These are made of carbon fiber sheet, they are thick and look quite robust, so they should survive most type of crashes. The wheel hubs with the axles fit on the arms with a smart way so as to be able for the user to adjust the pressure on the ball end, thus achieving the least possible friction with no slop.




 4. Suspension Arms installed on the chassis
In the past I 've had some bad experience with cars that secured their suspension arms with ball joints and not shafts. The reason is that if the tolerances are not perfect then in most cases the suspension would bind and in order to fix that you'd need to enlarge the hole were the ball end nests, and this will require a lot of handwork and in the end some slop will be visible. The A700’s suspension arms manage to achieve perfectly free movement without any slop and that is possible because of the tight tolerances (how many times am I going to say this word in this report?) and because of the smart, two piece system where between the Pivot ball and the suspension arm there is low friction ball cup which eliminates any gaps between the arm and the pivot ball while providing frictionless movement.




5. Now a short demonstration of the quality, fit and finish of the aluminum parts.
Gearbox, steering rack, diff, spool, damper, battery holder and a few more..




6. Dampers.

This is I believe the biggest innovation on the A700.  It is hard to explain how they work so I made a short video showing the motion of the suspension arm when pressed under load.  The result is very impressive with a nice smooth movement. Through this system you have the ability to adjust independently the ride height,  the spring load, the damping effect or both of them combined. Adjustment is easy and quick, by moving inwards or outwards the damper or by adjusting the Spring Rating Screw that sits on the shock spring.

7. Steering
Not much to describe here.  A steering rack that sits on three ball bearings the outer one being adjustable thus you can achieve better balance between minimal slop and friction.  Also the whole steering assembly has adjustable position on the chassis for better allignment with the ackerman positon on the steering blocks and the servo.


8. Gearbox
The gearbox houses the gears and in the front the steering rack as well.  The gear shafts are supported by double bearings in front and a single bearing at the rear. The rear will be further supported when the spur gear holder is installed. The fit is again incredibly precise with absolutely no movement at all of the bevel gear once installed.




9. Gear diff
The gear diff is a work of art. Aluminum art that is. The housing is paper thin, thus minimizing the weight and the outdrives are made of hard steel, the color of which resembles that of our familiar spring steel. The internals are made by Spec-R and as I had in my possession the optional carbon gears I installed these.  What is impressive is that the small carbon gears that I used from the Spec-R optional kit require some resizing in order to fit in the tight space inside the gearbox and the standard gears that are included in the kit have already been resized to the required dimensions for a perfect fit.



10. Upper camber links and turnbuckles
A testament to the high quality of this kit is that such simple parts can look so nice. The turnbuckles are very lightweight aluminum and have a beautiful gun-metal color. The plastic ball ends are of high quality material that fits perfectly to the thread of the turnbuckle. They are not too tight nor too loose.
 
I initially installed the gearboxes without their covers in order to show how the drivetrain looks installed.





11. Middle shaft holder to eliminate any vibrations on the main centrla shaft that connects the front to the rear gearbox. Very smart!
12. Spur gear installation. Another very smart design which results in super quick spur gear changes. The spur gear holder has two small pins which feet snugly in the holes of the spur gear and then the whole assembly is secured by a very light nut. It takes no more than 2 minutes to make a spur gear change.



13. Front bumper, body posts, battery holder
The front end is similar to most current designs with a foam bumper that houses the body posts. The rear end on the other hand has some very unique body post holders which also have the option to hold horizontal body posts, a common feature in the cars of most top pro drivers who want to avoid the body being tucked in when hit from behind. Super nice finish again, with dark gun metal anodizing and a small M2.5 screw to secure the body post.

15. Final thoughts.
This is by far the highest quality kit that I’ve ever assembled, and I have assembled quite a few ‘high end’ kits, from Xray to Tamiya, HB, Yokomo, CRC and a few more. The most impressive thing is of course the innovative design which would have been a complete failure if the quality did not match the demands of this design. Oleg and his team have succeeded perfectly in supplying a kit of the highest standards.
This kit is for the expert only and requires good knowledge of assembling technics. It does not require any hand fitting or corrective action, it is just that some parts are so tiny and require finesse to install that the inexperience hobbyist may find it very hard to succeed and may damage the kit before it is even used on the track.
Positive
*--- Design and innovation
*--- Quality
*--- Fit and finish
*--- Looks, visual appeal
*--- Unlimited tuning options
*--- Optional & additonal parts included for:
        a) drive train orientation
        b) upper link position (long or short)
        c) parts that may be lost or damaged during assembly
*--- Manual presentation, graph on suspesnion settings and gear ratios
*--- Description of all possible electronic installation orientation / layout
*--- Support from the designer himself on rctech and company website

Negative:
*--- Packing not as nice, box quite simple.

*--- Bags inside are not labeled / numbered.
*--- Manual could have a bit more detail on some assembly stages
*--- I received the kit for presentation purposes only but now I want to keep it and not return it so I'm in trouble!

Expect more updates really soon with electronics installation (this will be epic) and should the weather allow, first test impressions.
