Awesomatix MMCX - Mid Motor Conversion

Actually it is not mid motor. The motor is moved forward by some margin but still is located rearward. The point of interest here is the mid-spur location and the equal length belts front / rear. In theory this layout should provide a better and smoother power delivery than the unequal length belts of the current traditional layout.


In practice, it seems to deliver as it showed great pace in the hands of Freddy Sudhoff at the recent IFMAR World Championships in South Africa.

AWESOMATIX was the highest placed team without a professional driver and the margin of speed from the top performing cars was very small, if any.
In fact on his Q2 run Freddy was on course for top qualifying until he had contact with a board on the very last lap.

I have not tried it yet but I cannot doubt much the designer's Oleg Babich ideas as so far most of the upgrades he introduces seem to produce better pace.

This new design calls for a re-arrangement of the electronics layout. So far the most common and the proposed installation is to place the speedo behind the motor, and keep the receiver and cooling fan in front of the motor. This keeps the balance of the chassis at the desired point and also cooling of the motor is aided since the airflow of the fan follows the airflow of the car running.

Here is the suggested motor / speedo installation:

Me being me.. I tried the other way around. Why? well I did not enjoy seeing the speedo so far back.
Since I had long leads from the servo and speedo I could place the receiver way back and with some carbon spare pieces I made a fixing point for the antenna.
I did not place any weights up front and added 20gr of weight at the back which seems to have worked in achieving the desired center of gravity being a few mm behind the spur. I cannot say how much mm as this is top secret info and if I tell you I will then have to make you disappear!

Long story short.. here is my car: 


  1. Do you have any better pictures of your rear ars inner connections? How are those attached? I ran the mmcx last week here at ASR and love it.

  2. well, I cannot post photo in comments.
    Got an email?

  3. How cool was that having a full Car diversion System best 6x9 speakers Through this I really makes the most of my ride each time uniquely while out and about with a few companions. So amazing!

  4. I can set up my new idea from this post. It gives in depth information. Thanks for this valuable information for all,.. Wohnmobil kaufen Elmshorn
